Our take on the Alpine MRP-F300

by Buck Pomerantz
Alpine

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Alpine Authorized Online Dealer

V-Power amplifiers deliver the sound quality that made Alpine famous. Highly efficient power supplies housed in sleek black casings guarantee that these amps stand out in performance and appearance. The thermal management system dissipates heat and saves power, so your V-Power amp will run reliably for years to come.

The MRP-F300 4-channel amplifier sends 50 watts RMS to each of your front and rear speakers, or switches to 2-channel mode to power a pair of subwoofers. You can also switch to 3-channel mode, then power a subwoofer with 150 watts RMS while the other two channels power a pair of full-range speakers.

High- and low-pass filters put you in command of the frequencies that reach your speakers, while the bass boost is armed with plenty of low-end punch. Preamp- and speaker-level inputs allow you to connect this amp in almost any vehicle. Let a V-Power amplifier transform the sound of your car's audio system.

Highlights:

  • 4-channel car amplifier
  • 50 watts RMS x 4 at 4 ohms (75 watts RMS x 4 at 2 ohms)
  • 150 watts RMS x 2 bridged output at 4 ohms (4-ohm stable in bridged mode)

  • variable high-pass/low-pass filters (50-400 Hz, 12 dB/octave)
  • selectable bass boost (12 dB at 50 Hz)

Features

Power Supply: The MRP-F300 amplifier's power supply uses MOSFETs to convert DC battery voltage to the higher DC voltages needed for high power. It supplies positive and negative voltages around 0V, rather than around 6V as with conventional single-polarity power supplies. The result is higher power levels and a dynamic range wider by as much as 10dB.

Inputs: The amplifier offers both line-level and speaker-level inputs for 4 channels. The supplied speaker-level input harness allows you to connect this amplifier to a receiver without preamp outputs; aftermarket or factory.

Line Outputs: This amplifier has a pair of non-fading stereo RCA line outputs. You can use these outputs to daisy-chain another amplifier without having to run additional signal cables from the receiver.

Terminal Covers: The amp comes with two plastic covers that protect and insulate the RCA, power, and speaker connections. Four supplied machine screws attach the covers to the amplifier.

Controls

Gain Controls: This amp has independent front and rear channel gain controls.

Crossovers: Both front and rear channels have independent high-pass and low-pass crossovers. The crossover points are continuously variable from 50-400 Hz and the slope of both is 12dB/octave. Each set of channels has a high-pass/low-pass/off switch.

Subsonic Filter: This amp utilizes a subsonic filter at 15Hz to eliminate super low frequencies that can rob power and damage speakers. The subsonic filter operates at all times; it cannot be turned off.

Bass EQ: The Bass EQ circuit provides a fixed boost of 12dB at 50 Hz for the rear channels only. The Bass EQ can be turned off and does not function when the amp's rear-channel crossover is set to high-pass operation.

Connections

Left Side Of Amplifier:

  • GND (ground): gold-plated screw terminal, 0.33" wide
  • Battery: gold-plated screw terminal, 0.33" wide
  • Remote: gold-plated screw terminal, 0.33" wide
  • Speaker Outputs: gold-plated screw terminals (8), 0.33" wide

Note: Alpine recommends 8 gauge power and ground wire (minimum).

Right Side Of Amplifier:

  • Line Inputs: 2 pair of gold-plated stereo RCA jacks
  • Line Output: 1 pair of gold-plated stereo RCA jacks
  • Speaker Level Input: Molex plug input for supplied 4-pin harness

A solid reliable choice in power, great price

Written By flyguy, TN on Wednesday, April 09, 2014
Crutchfield Customer Review (What's this?)
 
I have always had a crush on the smaller Alpine amps. I have used these through the years in a lot of my systems. The key to this or any amp performance is a quality installation with quality wires. I bought this amp b/c it has H/L x-overs on both the front and rear channels. This amp does feature a bass boost function on channels 3 & 4. After some tuning, I decided not to use bass boost on the amp on the kicker 6x9's and use the more adjustable audio functions in the radio, and set the x-overs on the amp as back up if the radio ever got reset. The end caps hide/protect the connections on both sides of the amp. This amp was a good size , but easily fit under the pass seat of my 04 Ram quad cab.
Pros:
Reliable Alpine quality, great features for the price. the gains came preset at 50%. After getting the new radio, amp & speakers installed, i tweaked on it for a while and decided to turn off the bass boost in the amp, and set the gains at 50%. This should be plenty of power for most 4 channel mids/highs set up. This amp could provide a reasonable amount of power in a 3 channel setup, (small sub, a pair of separates)
Cons:
Be careful when installing them on a uneven truck floor through carpet etc, one of my screws was too short, thus breaking the little plastic mounting tab on one corner of the amp. no big deal, you never know it because of the end caps covering up the mounting screws and connections.

Are you serious?

Written By Impressed in CA, California on Wednesday, April 02, 2014
Crutchfield Customer Review (What's this?)
 
I have Alpine SPS 610 C component speakers in the front doors and Alpine SPS 610 Coaxial speakers in the rear of my 1996 Tacoma pickup. The speakers are rated 80 Watts RMS. My 22 Watt RMS Kenwood head unit was just not up to the task of bringing out the best in these speakers. I decided to look for an Amp to help these speakers sing. I talked to several of the extremely helpful CSRs at Crutchfiled before making my choice. Some of them suggested the the Alpine MRP-F300. My biggest concern was that the Amp have enough power to push the 80 Watt RMS Alpine speakers. I am not talking about blowing out my neighbors but giving me strong, clear sound. I was not sure the Alpine MRP-F300 at 50 Watts RMS would have enough UUUMPH. I finally talked to Marshall who listened very intently to what I wanted. After a thorough discussion of my system and what I was trying to accomplish both now and as I add a sub he agreed the Alpine MRP-F300 Amp was a good fit. So I tore everything out of my truck cab and wired it for the amp with great anticipation. The moment of truth came when I fired up my system with Joe Walsh's Funk #49. I was BLOWN AWAY! I have been listening to this song since it was first cut and I was now hearing nuisances I had never heard before, not just loud but clear. Are you serious? I would have never thought that this 50 Watt Amp would make these 80 Watt speakers sing so beautifully. But it overwhelmingly does. Get one of these amps while they are still available!
Pros:
Strong, Clear sound. Well built. It's an Alpine...
Cons:
Are you serious?

I drive a 50 year old car as my daily driver. It's a 1963 VW Beetle. From the factory it had a radio delete plate, and I didn't want to change the dash or have to listen to commercials or dj chatter .... So I bought this little amp and was able to hide it and the speakers and just plug it up to my Iphone when I'm in the car.... Works great..!!! If your going for some record breaking db level, this may not be the amp for you...., but it's plenty loud for me. My wife and kids all keep telling me to turn it down... This amp small = great Plenty of power = great Since I've been running it it's been cool or warm to the touch, not hot at all...= great Price = great I could not be happier !!!!
Pros:
Small, cheap, Quality brand, works great,
Cons:
I have nothing bad to say about this amp or the service from Crutchfield....

Within all honesty alpine has blown me away with this one. They are able to pack so much power into such a small amp thats its amazing. I was running a r300-4 by rockford and let me tell you this one beats it out of the water. This thing took 6 hours of abuse and still ran pretty cool. This is a bargain for the price!
Pros:
Compact design. Really puts out stated power. Price is unbeatable.

Mighty Amp, Small Size

Written By DayGuy J, Washington, DC on Tuesday, February 25, 2014
Crutchfield Customer Review (What's this?)
 
I purchased this amp to replace an aging Orion 5 channel that had served it's purpose after 10 years and two different cars. I was replacing the complete sound system and wanted a reliable amp to power my separates front and rear. My old amp was monster in size, and always ran hot. I know of Alpine's reputation as a leader in this field. I reviewed the amp extensively at a local vendor and read review after review before making a final decision. I ordered it and had free 2 day shipping, giving me enough time to prep my vehicle for the install. Install was a breeze, setting it up alongside the 2 Alpine MRV-M500 amps for my subs.

Overall I am very satisfied with my experience with Crutchfield, prices are competitive. They are very knowledgeable in providing full details of products.

As for the amp, I am currently waiting on sound deadening for my car, and going to do a similar install on my brother' car in the coming week(end).
Pros:
Price, size, performance
Cons:
None noted

4-Channel Use

Written By Chris M., Massachusetts on Tuesday, February 25, 2014
Crutchfield Customer Review (What's this?)
 
Recommended by the Crutchfield staff. Absolutely no clue how to upgrade my sound. Kept my factory HU, upgraded door speakers and added a mono amp/sub. Powers my speakers amazingly. Max volume before speakers, 33. I can actually surpass that volume at 15. A very noticeable cleaner and more quality sound. Would recommend to any person wanting to add power to their speakers at a very reasonable price.

Received the amp DOA with the front channel. Crutchfield's service team sent a replacement right a way. "Thank you Crutchield". The replacement works like a charm. I have always used Alpine amps without hesitation due to their performance. This amp delivers for the low price. I am an audiophile listener at home. And this amp does just fine.
Pros:
Easy to set and the power is perfect for my situation.

Well built unit would have come with a 5 star rating if there had been a wiring kit available mainly a 70 amp fuse, a remote cable and grounding strap
Pros:
Excellent value. discount on manufacturers retail price , excellent customer service which then recommended a full price replacement. Not really in my budget so will have to wait and see if the recommended unit goes on sale or the customer service will discount the recommended replacement.

Good amp for the money

Written By Josh, Tn on Wednesday, January 08, 2014
 
Purchased this amp to run my infinity kappa compinetns in the front and kappa coaxials in the rear of my 06 tacoma. Running it off of a premier head unit with 4 volt output with internal MOSFET amp. This amp is clean with no noise no pops or thumps of any kind. I can crank it further than what my ears can handle. It also fit Nicole under my driver seat of my tacoma access cab with no trouble at all and isn't even visible. I was nervous about buying this amp due to the cheap price but man am I glad I did.
Pros:
Great amp for the price and compact size.

This has been a great amp. I installed it in my wifes 2012 Hyundai Elantra to run some Infinity Reference series components in the front doors and Kicker coaxials in the rear. Sound is loud and clear. My wife listens to it pretty loud during her 45 minute commute and even during scorching summer temperatures it has never overheated.

Amazing clarity to aftermarket speakers!

Written By Joey P, Cincinnati, OH on Thursday, December 19, 2013
Crutchfield Customer Review (What's this?)
 
One of my door speakers blew in my 2002 Mustang GT with the Mach 460, so I just decided to replace the whole system since you can't find OEM replacement parts for the Mach 460 anymore. I replaced the 2 factory amps with just one of these amps and WOW did it really help wake up all 4 speakers. I also replaced all 4 speakers with Kicker CS68 speakers, and I also replaced the stock head unit with an Alpine HD137BT head unit. This amp went great with all the other new components. All the other 4 channel amps that I looked at were more expensive and I couldn't be happier with my purchase. Don't ever hesitate to buy anything Alpine, they're always #1 to me when choosing car audio products. My system now sounds 100 times better than the original Mach 460.
Pros:
Provides great power to all 4 speakers. Adds much more bass to all Speakers. Blends in well with the carpet in my trunk.
Cons:
NONE!

powering 4 JBL GTO 6.5 speakers

Written By mjberger, Phoenix, AZ on Wednesday, December 18, 2013
Crutchfield Customer Review (What's this?)
 
I recently updated my stock HU with a Kenwood and replaced my stock speakers with 4 JBL GTO 6.5 3-way speakers. They sounded really nice without the amp powering them, but WOW...when I installed the amp to all 4 speakers the sound really increased in quality. Everything is crystal clear and even the bass is much improved with the smaller speakers I don't think I'll put in any kind of sub. My speakers are 2 ohm so these actually put out 75 watts RMS to 2 ohm speakers which is perfect for the speakers that I have.

Great History

Written By Chris L, Richmond, VA on Wednesday, December 18, 2013
 
This is a great little amp and for the price is a steal! I purchased my first one a few years ago and had it driving two Alpine type R 12's in a 96 Landcruiser. It was waaay more than I needed but I didn't find myself downsizing the system. That same amp is driving 4 10" JL Subs now in the same vehicle driven and listened to everyday by my brother. Reliable.

This purchase was for my 4Runner and driving a 2-ohm JL W3 10" sub. It's a perfect match for power, small footprint and easy to tune. It would be nice if it had a parametric adjustment to the boost but that's pretty picky in the price range.
Pros:
Price, size, ease of installation, clean look - ALPINE
Cons:
None

Pros:
Great amp and great service

I do not know a whole lot about what makes a good amp for normal speakers. But i tell you the customer service they run here really know their stuff. So i gotta say when i plugged everything in which was a breeze~ i was really blown away by the fact it was clear sharp and loud. :) I have my amp Gaines turned Down to basically nothing when i crank my radio it really does shine.
Pros:
everything works perfect
Cons:
nothing!

Good, clean power

Written By Zack, Billerica, Massachusetts on Tuesday, October 01, 2013
Crutchfield Customer Review (What's this?)
 
Great amp for the money. Delivers more than enough power to my 4 Boston Acoustics 6x8's (each rated at 50 watts rms). The beauty in this amp is the ability to play at 75 watts x4 (2 ohms) or bridge it and get more power. High and low pass filters mean you get exactly the sound you want coming from each speaker. Cranking the gain results in crazy volumes, at least in my speakers. This amp makes me question whether or not my speakers can really handle 160 watts peak. I have to put the gain down a lot to be able to use the full volume range of my head unit without distortion. I ended up raising the gain and only using volumes 1-30 on the unit (goes to 50). Other than the great power, this amp transfers great quality as well. It also looks good, and is small enough to fit under a seat or anywhere else, really. Installation was a little tricky, considering i had to use connectors on every wire (may have been my fault for using too thick of speaker wire, though.
Pros:
Great power, clean signal, great look, small size, filters, bass eq, plenty of gain control, barely heats up
Cons:
installation was tricky, small wire terminals, can probably blow my speakers easily (not really a con, probably my own fault, again)

MRP-F300

Crutchfield Customer Review (What's this?)
 
Finally my speakers and amps are installed. I'm running 4 Polk 571's and 2 1001's through the MRP-F300 at 2 ohms. Infinity BassLink completes the ensemble. The Alpine powers those speakers with no issues. I'll spare any boring details as those that know Alpine, know quality. If your running speakers off just the head unit, the Alpine will provide quite a surprise in the boost of sound quality. The professional I had install the system had nothing but positive comments. Special thanks to CRUTCHFIELD for many hours of patience in answering ALL of my questions and providing advice on having a solid setup without breaking the bank. MY SYSTEM RIPS.
Pros:
No disappointments.
Cons:
None

sweet amp

Written By JodyD, Houma La on Wednesday, August 28, 2013
Crutchfield Customer Review (What's this?)
 
I have this amp installed in a 2012 ford f-150 super crew. Its mounted under my front passenger seat powering 4 memphis m-class 5x7" coax. speakers ( with the external crossovers). It is running off of my factory deck so i used some PAC line converters. This amp make my speakers scream clarity. The speakers are rated for 50w rms and that is what the amp pushes. I could not ask for better. There is not much room under my seats to mount an amp but it def. fit with a piece of painted black 3/4" mdf board that the amp is screwed down to (had to lift the amp a little for the speaker terminals to clear the seat mounts on the floor). Installs clean and neat. I also have a mrp-m500 pushing one 10" phoenix gold in a custom ported box that is under the driverside rear seat. There was just enough room to mount the amp on the passenger side under the rear seat. All in all the whole package is awsome. Oh and just to help, so you do not have a head ache if you decide to install an aftermarket amp on a factory deck, go and get yourself what is called add a circuit or add a fuse and install that inplace of a fuse in you panel that works with the ignition. There is a wire that comes off it that can be hooked up to the remote wire to turn that amp on and off, and you stab you previous fuse into that and if you would like you can install another fuse for the remote wire there are two slots. Thanks Crutchfield for that tip it helped out!!!
Pros:
sounds awsome, small size, plenty of power
Cons:
does not accept 4ga. power and ground wire you will have to somehow find some connectors or clip back the wire to fit in the terminal

Worth way more than I paid for it!

Written By Lew, Montana on Monday, August 26, 2013
Crutchfield Customer Review (What's this?)
 
I bought this on sale. I wasn't even going to buy an amp because I was just going to upgrade my stock deck to a low end Kenwood and run off deck power, but the deal was too good to pass up, so I bought them both. I initially just used this as a 4 channel amp to power four 6 1/2" Eclipse speakers that came with the car when I bought it. I only turned the gain knob up maybe an 1/8 of the way before it was too much power to the speakers, but the sound quality and volume was 100% better than the stock deck. Out of curiosity, and the search for just a little more low end, I picked up a pawn shop Kenwood 10" sub for $30. I put all four 6 1/2s on channels 1 and 2, and bridged the sub on to 3 and 4(after a call to Crutchfield to check and see if technically could, of course). WOW! The Eclipse speakers, that sounded like they were blown with the stock deck, got even clearer and louder and the sub pumps! I think this is the clearest, most balanced system I have ever put together in 20 years. Not the loudest, but for a total of $260 (deck, amp, sub), I could not be happier.
Pros:
Incredible value, easy install, crossovers and gain adjustments work wonderfully
Cons:
none yet

Alpine MRP-F300 - solid amp

Written By zlordraptor, program manager on Monday, June 17, 2013
Crutchfield Customer Review (What's this?)
 
If you are looking for a solid 4-channel amp, then the Alpine MRP-F300 is it. Don't be fooled by 50 watts RMS, the Alpine MRP-F300, tuned correctly, can max-out any set of speakers' dBs, mids and tweets, and turn'em into a gut wrenching, eardrum piercing experience. The adjustment features are perhaps one of the best things about the Alpine MRP-F300, with total control of filters, crossovers, and gain, there is no reason why you can't get the exact sound you're looking for, plus, spec-for-spec, you can't beat the price of this 4-channal amp. Need proof, take it from me, I ought to know, this is the second Alpine MRP-F300 I've purchased.
Pros:
clean, clear, and loud!
Cons:
nada!

This is a great little amp that fit nicely tucked away in my trunk. I am running 2 Pioneer 6x9s and 2 Pioneer 61/2s in my Honda Accord coupe and it sounds like I have a full blown system.

its been along time since i bought a amp i am 40 years young now had lots of amps when i was in high school but since i only always upgraded speakers an head units an they sound ok mutch better than stock and when i do somthing i do it right, this amp amazed me for the money! i have a 2012 suzuki equater crew cab truck (nissian frontier with zuk badging). installed a kenwood kdc-hd545u head unit got from crutchfield a few years ago great unit 4 single din. installed mtx 6 9 in front doors that i also had for about 7 years (was installed in my old honda suprised they were in as good cond as they were) also installed new polk audio dxi 650 in rear door got all mounting instructions and panel tool with order. instalation was a treamendous help would have never been able to do it as neat or as easy without crutchfields help. now when i first fired the amp up i was extreamly impressed then after i got the amps gain settings set WoW the clairity i was just amazed even when i faded rear new polks out and just listened to old setup with just amp installed was amazed and alot more punch than i expected for just 50 w per channel, with the polks sounded even better filled the cab with full sound but they a have little trouble handelin bass at loud volumes mtx 6 9 are a bassy speaker so works good for me till i can get a sub. not running crossover settings yet but did play with them they work very well alot better than the stuff i remember back in 90"s next step is getting a 10 sub.
Pros:
love the amp. amazing clarity!!!! best little amp 4 the money looked at alot of amps an and did alot of compairing could not come close to it unless i spent twice the money.also gonna get matching mrp-500. alpines 500 watt mono amp if it is as good as this one it will be all i need for my small truck. caint wait till i get rest of system in place will sound great thanks crutchfield for all the help...
Cons:
only thing i can say is i read some reviews the plastic monting feet seem to break off i had no problems yet but you got to be careful when mounting and can not hammer mechanic it.:) they seem durable to me and i screwed it right to the floor under rear seat and it was not a real flat surface just b careful i was easy on the mounting did not over torq but i can see why people might have problems . mine is very sturdy dont move or vibrate

After installing a Clarion 501 CD Reciever, a pair of Polk Db651s in the doors, and a pair of Polk Dxi460p plates in the pillars on my 2004 silverado, I was a little disappionted with the lack of depth and lack of volume of the music.I'm not one to write reviews but after installing the Alpine MRP-F300 to the system - WOW! - What a difference! The sound is much warmer and depth & detail is much improved along with more volume than I will ever need.If you are considering upgrading your system with a new mid-power amp, (50watts rms x4)I highly recommend this one.I plan on adding a sub later and this amp has a pair of line outputs to daisy chain another amp.
Pros:
Alpine quality build, solid sound

Alpine MRP-F300 - Watch out for stuck switches!

Written By FRECHA, Dallas, Texas on Monday, February 11, 2013
Crutchfield Customer Review (What's this?)
 
Sound output from this amp is good. it was easy to install but was disappointed that the covers were made of plastic instead of metal like the rest of the unit. Directions were easy to use. Only gripe I have with this unit is that I found the HARD way that the switches that control the channels for the front and back can sometimes get stuck. I tested the unit and was puzzled why sound was coming out only on one side of the vehicle. I thought the problem was wire based so i proceeded to troubleshoot the wiring and after an hour of going through the wiring and rechecking connections it ended up being a stuck switch setting that controlled the front 2 channels. The settings were set properly from the beginning but for some reason when the switch was set it didnt go all the way. This was after i had to call tech support for assistance. The person that assisted me told me that sometimes this happens to this unit and to always play with the switches to make sure they set to the right setting. Wish i knew that ahead of time....
Pros:
Great sound - no interference detected. Nothing but clean crispy producing sound. Supports various setups.
Cons:
Switches used to dial in settings are not dependable. Size of unit is also large and plastic housng cover was cheap looking.

Just installed this amp in my 2007 Tundra along with 4 Polk speakers. I usually don't take the time to post reviews on products but i like this amp so much I had to voice my opinion. This amp rocks! It may be only putting out 50W per channel but i can't even crank it half-way without my ears bleeding. Crisp clear sound even at high volume levels. I also installed a new Pioneer AVH 3500 which contributes to the high quality sound. Can't say enough about how pleased I am with this amp.

This amp made a world of a difference in sound, but the mounting feet are made of thin plastic and two of them broke off when screwing them down using very little pressure, but I was able to gorilla glue them back on stronger than ever.
Pros:
Very nice sound quality, I think you can mount the f500 mono amp on top of this one to save space.
Cons:
Frequency dials seem to be a little off, cheap plastic mounting feet, difficult to connect power and ground if you're using anything lower than 8 gauge.

Cost effective yet so powerful and clean, this amp rocks!

Written By Pete, Demarest on Friday, September 28, 2012
Crutchfield Customer Review (What's this?)
 
I purchased my 2012 Mazda5 Grand Touring last September and first thing I noticed was that the stock speakers sounded horrible. Thinking it was lacking bass, I installed a Kicker CVT 10" sub with JL JX250/1 mono amp. I had difficult time trying to find the right setting for the amp. Then realized that the car was too noisy on the highway so started to Dynamat the car. I then purchased the Focal Access speakers (component up front and 2 way in the rear); during which I discovered that the tweeters were basically bridged to the existing door speakers. I the replaced the factory speaker wires with Monster XP. Though it sounds okay after that with bass sounding much better but was now overpowering the mids as power was lacking. I then started looking and found the Alpine MRP-F300 both economical and attractive. On top of that, it had rave reviews on Crutchfield.com. So I went ahead and ordered the "Open Box" unit (which I trust Crutchfield wholeheartedly) which was delivered two days ago. This morning, I started the installation of the amp -- which I sort of knew that it would a lot of work -- and it was. Hardest part was trying to get to the wiring harness on back of the radio. But I endured and after about 6 hours later, I finished the install. I fiddled around with the settings on the amp played Vivaldi's Four Season by Janine Jensen. I was literally blown away, it was so clear, so punchy, and bass was there but no longer overpowering. I'd have to say, money well spend!
Pros:
Clean, punchy, compact, quality assembly throughout.
Cons:
None

Written By Brian, White Bear Lake, MN on Tuesday, September 11, 2012
Crutchfield Customer Review (What's this?)
 
Right after I purchased this amp I started thinking maybe I should of spent more, maybe 50 watts per channel would not be enough power to push my 2 Polk Audio MM5x7 and 2 Infinity Kappa 6x9's effectively. After installing this amp with the JVC Arsenal deck my worries were put to rest. This amp provides a lot of clean power. Enough to wreck your ear drums with Zero distortion. To the folks that say this amp doesn't provide enough power or bass to your 6x9's, get a good quality wire kit, make sure you have a good ground connection and turn off the bass boost unless you are running subs, it will make your bass sound horrible. This is a great amp.
Pros:
Great power and sound quality.

Crutchfield Customer Review (What's this?)
 
I'm giving this a 3 star review because I feel it does it's job fairly well. I used to really be into car stereo equipment. I spend a lot of time in the car, so decided it was time to update my system. I had an Alpine head unit, and added an old school RF Punch 75HD for the front, and another for the rear speakers. Bass was awesome with my 6x9s! For some reason, I decided to swap out the old school amps in favor of a single 4 channel, then hook up one of the RFs to my old school Kicker Competition 12s. I figured a NEWer 4 channel amp would be better than my 20 year old RFs. Boy was I wrong! I lost practically all of my bass(6x9s). (I do not have the Kickers hooked up because I didn't want to lose the trunk space.) The volume is no where near what I was getting out of the RFs, but I figured that would be the case since the RFs really pumped the power out. This thing still was louder than the stock Alpine unit, but again, no where near the RFs Bass output. I tried the different options for bass boost, but still nothing. The low end just falls off. I have since sold the RFs(my bad), and am considering buying a new one to replace this amp. I have read reviews on other amps, and just as others say, you get what you pay for. Bottom-of-the-line sucks, no matter what brand.
Pros:
4-channel amp that does it's job.
Cons:
lacking bass response

What I was missing...

Written By MonsterP, Colorado on Tuesday, May 01, 2012
Crutchfield Customer Review (What's this?)
 
It's all true - clean power, powerful. I'm running a KDCX996 head unit, Pioneer 6x9s in all four doors, and 10" JL Powerwedge sub in a supercab F250. Thought I could live without an amp on the speakers, but hey, I gave it a shot. After adding this amp, my system is complete, just doing all the final tweaking. Completely satisfied, highly recommend, and I'd buy it again.
Pros:
Clean, powerful
Cons:
Wish the ground and power inputs on the amp accommodate 8 gauge wire a little better

Alpine Amp hits the mark

Crutchfield Customer Review (What's this?)
 
I put this in my sons truck for Christmas along with an Alpine sub and I was impressed on the amount of punch the amp had. I used it to power 2 way Boston's in the doors and I bridged the amp to power the 10" sub. Worked out very well.

GREAT AMP

Written By C.M., Tampa, Fl on Thursday, January 12, 2012
Crutchfield Customer Review (What's this?)
 
I installed this amp in a 2003 Ford Ranger. It is powering (4) Infinity 6832cf 5x7/6x8 speakers using the factory head unit. It has more than enough power to push the Infinitys. Very clean power and sound with this amp. I have the gain turned up a quarter of the way and it provides plenty of power to the speakers at that level. I can turn the volume all the way up without the speakers distorting. The amp has a speaker level input connector that allows you to use a factory head unit without RCA outputs. If the head unit has RCA outputs there are RCA inputs on the amp as well. It also has Pre-Out Jacks (RCA) for connecting a separate subwoofer amp. Install time and difficulty depends on the location of the amp so that will vary. I put this one under the seat and it took about two and half hours. Set up is straight forward. Adjust the gain using a good clean sounding CD as a source, then adjust the crossover settings to your liking, more/less, high and low end and you are done. I do highly recommend using a CD for the source and not the radio because of the quality of a CD is much cleaner than a radio signal. Over the last 35 plus years I have owned and installed many brands of amps including Alpines before this one and have never had an Alpine that was properly installed fail. I am not saying that this is the best amp out there. There are certainly better and more expensive amps to be had. But I will say that given the quality and price of this amp it is hard to beat.

Bought this to run to my 6.5" Polk Audio DXi6500s components and Poik Audio DXI650s (in the soundbar). They do a great job making the speakers louder although it took me some time to find the right adjustments for my ears.

Exactly what I needed

Written By Adam, Baltimore, MD on Friday, July 29, 2011
 
I upgraded my base model 2010 Toyota Venza with a power amp, Sound Ordanance powered sub, 6.5" kickers in the rear and 6x9 Bostons in the front. What a great difference the overall system feels from the factory base model.

My goals included that I didn't want to spend a lot of money produce lots of high quality sound. I was going to buy a more expensive power amp that had a high wattage, but the installer recommended this one because of his positive experience with it. He said (and I have no reason to doubt him) that this amp produces the wattage it states it will while others will not actually produce the wattage advetised. It's extremely clean and really makes my bostons sound perfect. I kept my factory head unit and it works great!

Nice Amp!

Written By coates52, Sioux Falls on Monday, July 04, 2011
Crutchfield Customer Review (What's this?)
 
I didn't want to tackle installing this amp, the Polk Audio db6501 6-1/2" Component System speakers, and the JL Audio CL441dsp Factory Stereo Signal Processor myself, so I had a local shop install them. My 2011 Avalon base model had cheap speakers and a head that can't be upgraded (because of all the climate control electronics in the area). Crutchfield recommended the Signal Processor to clean up the head's output. They did a nice job installing the components, but a lousy job of tuning it.

After reading extensively online: I switched the Polk's passive crossover to -3db and recalibrated the Signal Processor with the head volume set to half of its maximum volume. That was the starting point to get the amp tuned correctly. With the head set completely flat I made sure the amp's channel switches were set to Full Range and then followed the directions for the amp: turn the amp channel volume up until the sound distorts and then turn it down a notch at a time until the distortion stops.

I now have a car sound system that works for me. Even though the components were installed by professionals there was no bottom and hardly any midrange. After taking the time to tune the system myself there is nice low end (enough for me), even though I don't have a subwoofer. The mids and highs are now smooth and balanced with the lows. For me the moral of the story is turn the amp up so it can deliver enough power to the speakers.

Thanks to Crutchfield!

Awesome Amp

Written By TBone97, Woodbridge, VA on Wednesday, September 22, 2010
 
I wanted to improve the sound in my wife's 08 Odyssey, therefore I called the experts.
Norman was very knowlegable and recommended the polk audio speakers (4) and the
Alpine amp for the power. The sound is amazing and a 200% improvement. The Tech
support was awesome and Adam entertained quite a few "Rookie" install questions,,
without laughing....at least not on the phone.
Thanks Crutchfield!

Alpine MRP-F300

Written By ZackB, Prescott, AZ on Tuesday, September 21, 2010
Crutchfield Customer Review (What's this?)
 
Like other reviewers here i didn't know what i was missing by not having this amp and
running only off the HU power.
The amp is currently powering two pairs of Alpine Type S
speakers, and now they sound incredible. Gains set at half with crossovers at 100Hz,
this amp delivers crystal clear sound, with no distortion (that is until the HU starts to clip).
Even after hours of hard use, the amp was still cool enough to touch! i would definitely
recommend to anyone that is looking for good, all around, solid sound.
Only one problem so far with this amp was the speaker level (line level) inputs seem to
have a lot of noise (hiss). so i switched over to the RCA inputs and the hiss disappeared
great amp!!

This amp made all the difference between having noise and having quality sound. I
didn't know just how much difference it would make. I have it in a 72 Duster, so besides
people just looking at the car, now they listen as well.

Small amp, great price, awesome sound

Written By Apollo, Sulphur, LA on Wednesday, September 08, 2010
 
Have this amp pushing 4 5x7/6x8 Infinity Kappas in the doors of my crew cab
truck and I'm very pleased with my decision on this amplifier. It handles the 2
ohm load of the Kappas extremely well. I have the gain one-third of the way up
and I can put my Pioneer DEH-3200UB on max volume and have zero distortion and
perfect clarity. Sounds just as good at low volumes as well as high volumes. I'd
recommend this amp to everyone.

Great amp for the price

Written By Joseph, Columbus, OH on Friday, August 27, 2010
Crutchfield Customer Review (What's this?)
 
I was always slightly skeptical about external amplifiers, wondering if there would really be that
much of a difference. Well, I can lay those doubts to rest. This thing sounds awesome. Pretty
small footprint for a 4 channel amp, sounds great, and good price. What else can you ask for?

I'm really glad that I upgraded. I thought my stereo already sounded pretty good just off HU
power, but this blows it out of the water. Well worth my time and money!

Nice Amp

Written By Tracy, Sandston, VA. on Monday, July 26, 2010
 
I have this hooked up with a Kenwood HU and (4) Polk db571 speakers and it drives the Polks perfectly. The amp is plenty loud even for 50 watts RMS and has a great compliment of adjustments to fine tune your sound. Very clean, clear, quiet power with quite a few ways to use it as far as 2-ch, 3-ch, or 4ch. It even has speaker-level inputs for use with a factory radio. Very nice amp and no other place to purchase it from than Crutchfield, you've got a life-long customer, I wouldn't buy my electronic gear anywhere else.
