Alpine Authorized Online Dealer

Thanks to impressive power output, affordable pricing, and exceptional reliability, Alpine's V-Power amps are consistently among our best-selling models. The MRP-M350 mono amplifier gives you awesome bang for your buck, and sports some "extras" that you'd usually find only on higher-priced amps!

Hook up the MRP-M350 to one 4-ohm sub, and you get 200 watts RMS; connect a second 4-ohm subwoofer and the power output increases to 350 watts! All that juice means that your subs won't just be loud, they'll sound clean and musical, too. A variable low-pass crossover lets you tune the output to match your particular sub setup.

The 15 Hz subsonic filter eliminates very low notes (those that are too low to hear) from your system, so your bass won't sound muddy. Plus, you'll want to take advantage of the BassEQ — an adjustable bass boost of up to 12 dB at 50 Hz! Speaker-level inputs allow you the flexibility to hook up the MRP-M350 to just about any system, and gold-plated terminals ensure that you get clean signal transfer both into and out of the amp.

Product Highlights:

  • 200 watts RMS x 1 at 4 ohms (350 watts RMS x 1 at 2 ohms)
  • low-pass filter (50-200 Hz, 24 dB/octave)
  • variable Bass EQ bass boost (0-12 dB at 50 Hz)
  • subsonic filter (15 Hz)
  • MOSFET power supply
  • preamp- and speaker-level inputs
  • blue power LED
  • extra-large gold-plated terminals
  • 8-gauge power and ground leads recommended — wiring and hardware not included with amplifier
  • 9-3/16"W x 2-7/16"H x 9-9/16"D
  • warranty: 1 year
  • Our 60-day money-back guarantee

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.

Powerful little guy, and well worth it.

Written By Jacob, SE Idaho on Saturday, January 19, 2013

I bought this amp used on craigslist, not expecting much since I didn't pay much being that it was already a few years old. I was pleasantly surprised. I have had it pushing 1 Memphis 15" at 4ohm for the last year and man does it hit hard. It fits perfectly under my rear seat in my SUV, and has performed beautifully. I'd recommend this to anyone looking for one.

Pros: Compact, Efficient, Powerful

Cons: None yet.

After 8 years of faithful service...

Written By Grogel, Lake Charles, LA on Sunday, November 04, 2012

I received this amplifier as a gift for my 17th birthday 8 years ago. In that time I've had to replace two subwoofers and transplant the entire system to a new vehicle. This amplifier has greatly exceeded my initial expectations and I could not be happier with Alpine's quality engineering.

The folicile eradicating power this amp outputs is impressive for its small form factor. It packs a massive punch when wired to a Type-R 10" 4 ohm dual voice coil wire in parallel. The single sub is all I have ever needed in both of my extended cab trucks. The sound quality is superb all around.

This amp has solidified my future business with Alpine. I am very happy with this product.

Pros: Lifetime++ Exceeded the warranty by 7 years and still going strong.

Cons: Does not drive the vehicle for me (I'm just kidding here).

This amp is a Monster

Written By Nicc_Cajun, Compton, California on Thursday, October 04, 2012

This amp is a sleeper. They say good things come in small packages, this amp proves that. I've got it pushing 1 15' Kicker Cvr. This amp amazed me , clean low bass. Didn't even have to max out the Gain. A definite Best Seller.

SICKEST AMP EVER!!!!!! i've had lots of different amps and subs and by far this one would shut those down in a split second, right now i have it hooked up to an MTX thunder 10inch in my pick-up and it rattles windows when i drive by and had it hooked up to 3 subs in a civic at one point and it would make your dentures fall out more then happy with it buy it!!!

Crutchfield Customer Review (What's this?)

This amp is awesome... I couldn't be happier. I'm pushing a single 12" Alpine Type S DVC (4 ohm), wired in parrell dropping it to 2 ohm. The amp is pushing 350w RMS and it packs a punch. Excellent clean sound quality, minimal space can't beat this amp. Try to find a high quality amp with this much power for anywhere near this price - you can't do it. Another great thing about is that its small enough to fit underneath my seat and never once has it gotten hot. Great job Alpine. Thanks Crutchfield

Best quality & power-to-price ratio you'll find

Crutchfield Customer Review (What's this?)

I bought this amp without hearing it too much based primarily on prior Alpine experience, but also because of the power it puts out and the low price. Buying Alpine products is a pretty safe bet considering their quality and history - and this amp is no exception. I have this pushing 2 JL Audio 10w1v2-4ohm subs (RMS of 150 each) wired in parallel (which is a 350w RMS 4ohm output) and let me tell you - this amp is worth every penny, especially compared to similar powered amps by other companies that cost two to three times as much. Excellent clean sound quality, minimal space can't beat this amp. Try to find a high quality amp with this much power for anywhere near this price - you can't do it.

Nice Power

Written By Scott, New Bern, NC on Tuesday, January 10, 2006

I have this amp, and it works great! I have it going to a 500w pair of Alpine 12"s in a box. It's a beast of an amp, great powerful sound for the size.

Excellent Amp!

Crutchfield Customer Review (What's this?)

This amplifier exceeded my expectations by a long shot! I have always been very careful to read all the reviews BEFORE I buy any product. When I read all the reviews for this amplifier they were great. I would recommend this product to anyone who needs a good punch of bass in their system but doesn't want to pay a bundle. I would definitely rate this amplifier up with the 'big boys'.

Alpine MRP-M350

Written By poppinwillys, Crestview Florida on Thursday, January 05, 2006

I purchased this amp because I was tired of dealing with cheap stuff for an example and I had always heard good stuff about alpine. Now I see why. This amp hits clean and hard. Really clean and Really hard. I have it hooked up to two mtx thunder 4000 12's. Im not exactly into blowing out my neighbors and everyong else on the road. But I can dang sure do it with that amp if I so desired. I've had it hooked up to a kenwood 12 and my friends 12's in a box, and it pushes eveything awsomely. In fact it hit so hard it makes his back window leak now. Why you would want something that loud I still dont understand, but I'll be the first to admit its really impressive. So you can go spend 500+ on a great amp or you can get this one for 179 and as long as its not were you can see it, You will never know the difference. So....go buy wont be sorry.

Take my word for it!

Written By mike, Slidell La on Thursday, December 29, 2005

Like another reviewer I also work in the car audio buisness and am also a MECP certified installer. And like him I sell ALOT of these amps where I work also. We use them on 2 type e subs or 1 type r and they push those speakers better than the P4004 (thats 400 rms!) Rockfords and at about $100 cheaper! Trust me this amp with 2 type e alpines and you are good 2 go. Customers that I recommend this amp to look at me crazy because its so small, then I take them outside to my co workers s-10 with it and 2 type e 10's and thats a wrap. SOLD! And unlike the v power amps (also very good amps) they dont need a 4 volt input to be at their best. I created an account just to let you all know just how BAAAD these amps are!

No disappointments for the money. Running it into 2 ohms on a sealed 10" in my trunk and only need about half of its gain or it overpowers the front speakers. Sounds clean and would definitely buy again.


Written By JPeabody, Rogers, AR on Friday, December 09, 2005

Just like everyone else who has this mini beast, I was a little skeptical before I hooked it up. I have it running to 2 10" JBL GT 100's, and it blew me away. The sound quality is uncomparable to what it sounded like before. I have it at 2 ohms and it is pushing somewhere around 350 watts. I can't believe how much louder it is! I would highly recommend this amp for the price. No dissappointments here!

Great amp

Written By Drew, c'ville on Tuesday, November 22, 2005

I got this amp to power my 12" Kicker L5 solo baric. I thought it wouldnt be enough power to push that sub to what i wanted but it came through with amazing power, and it has increased the accuracy of my sub. The digital controls definitley make it easier to fix your amp settings. This is all around just a great amp reccomended buy for everyone.

it will make your ears cry

Size doesnt matter

When i received this amp and i opened the box my uncle that helps me with all my car audio connections laughed at me. He said "that little amp aint gon thump nothin'" but when we were done and i turned on my head unit boy was he surprised. It was so powerfull it made my rearview mirror shake. This is a great amp.

What a steal

Written By mike, Antioch, IL on Thursday, September 29, 2005

this little monster is awesome. i have it installed in my protoge, and connected to my 12' alpine type E and by far the loudest sub/amp combo available for that price. this amp powers my sub like its a 1,000 dollar amp i love this thing what a great product at an awesome price!!!!! highly recomended

Best amp for $250 and under

I work in moble audio. i have this amp pushing 2 12" alpine type E in a sealed box. You deff get your money's worth. Great sound and even better size for the power. Just remember, "Its not the size that counts, Its the power behind it. Take my word for it. I sell many of these amps weekley.
I also have this amp in my 96 Vw GTI.

I got this amp runnin to my 10" 1,200 watt RE sub on a custum built ventilated box, It makes my sub sound like i have it hooked up to at least 1000 watts of amp power, Its so great i have won 1st place in competitions. Great clean bass louder then JL Audios W7, perfect amp for the perfect sub, highly recommended.

Im powering one 12" 300rms Infinity sub in a sealed enclosure and this thing makes my back go numb from the bass. Thats all I really have to say about the power coming out of it. Might swap out to a better sub but definitely not a new amp.

mini powerhouse!

Written By mike, Carmel, IN on Tuesday, July 05, 2005

I bought this amp for my 10" kicker sub and this thing is a serious bass machine! it puts out 200 rms at 4 ohms and when 2 subs are hooked up it puts out 350 rms at 2 ohm. Along with its inexpensive price this amp is small and will even fit in light weight trucks like my 2000 Ford Ranger standard cab. This is a great amp for somone who want s great bass for a low price tag.

Crutchfield Customer Review (What's this?)

After previously owning a Rockford Fosgate amp for several years, I was reluctant to go with any other brand, knowing how clean and powerful of a signal RF's are able to produce. Well, my baby finally just passed on one day, so when doing another system set up in my second Jeep Cherokee, I went with this amp after a lot of homework, and wow - what a sound! THUMPING lows, absolutely distortion-free sound, and many level options to work with to obtain that specific sound you're looking for. I'd also like to note that I connected this amp to the factory system, and because of the tuning capabilities on the amp, the sound in my vehicle is just PERFECT. And because of my discrete mounting location, (under the rear folding seat,) it's compact size and low-heat producing qualities made for an A++ installation. Running this amp to two subs, dropping it to a 2 ohm load, this is a VERY powerful sound machine. Highly recommended.

Nice Nice

Written By GhettoLife, Green Bay, WI on Monday, May 09, 2005

I bought this amp and hooked it up to 2 12" Alpine Type-E subs and wow.... This amp pushes these subs hard. I was suprised after running the system for over an hour at 95% to 100% how little heat was developed. I don't have extra cooling or anything, infact, I have it mounted to the back of my seat and my subwoofer box is right in front of it (not a lot of breathing room). I have the all of the settings on it bumped up a bit too from what they were at after install, everything at about 75% give or take. This amp is perfect for someone who does want to spend a ton of money but wants quality and loud bass.

I have been a fan of Alpine head units for years, but was reluctant to try their amplifiers. I decided to take the swim, and couldn't be happier. This has to be one of the cleanest sounding amplifiers I've heard. There are plenty of settings, which will allow you to tailor the sound to your taste. I am also impressed with the overall size(or lack thereof) of this amp. It is about the size of a shoe box, which gives you plenty of placement options. There is a reason that everyone so far has given this amp 5 stars. Now push the red button!!!!!

OMG!!!!!!!! i bought this amp for my two 12" rockford fosgate stage 1 subs and they pack a PUNCH!!!1 Idrive a 1994 ford f150 and i took out the back seat and placed these items back there and its packs a punch!!!!!!

Great punch for its size

Written By Joe, Dalton GA on Friday, April 22, 2005

Crutchfield Customer Review (What's this?)

This is an excellent amplifier for its overall size. I installed the amplifier powering a JL Audio Stealthbox, 10 inch driver wired at 3 ohms. I specifically chose this amplifier because my measurements put it exactly at the right dimension to fit on the backside of the interior brace for the trunk that the Stealthbox bolts to. The brace is well damped and triangulated so while I do expect it to have a sympathetic vibration it will be no where as bad as mounting the amplifier on the subwoofer box itself. I used the factory head unit and tapped into the speaker level outputs on the stock amplifier (another big plus for this Alpine amp) and this little powerhouse still vibrates my rear view mirror so heavily that I can't see traffic in my rearview. This is with the gain turned completely down and with the bass setting on the factory head down from the middle 25% (factory setting is 50%).

Great amplifier, great performance, will do it again if I buy another car that a Stealthbox fits...this is a highly recommended amplifier for a subwoofer installation since it is a Class D. Also great if yo're not a hardcore bass head that needs to vibrate windows at 100 feet but still appreciates feeling the vibratory quality of, say, a low C string on a concert doublebass.

excellent amp

Written By Rob, minneapolis, mn on Monday, April 18, 2005

i've had this amp in my car for over a month now and i dont think that i could be happier with it. it puts out a nice clean signal and is loud despite the lower power rating. i replaced an aging 225W class AB amp with this and i wouldn't have believed you if youd told how big of a difference it would make. i have it hooked up to a 10" infinity reference and i get lots of clean bass in my car. the other nice thing about the amp is the size of it, the thing is tiny. you can basically mount the thing anywhere because its so small.

Inputs and Outputs


Class D Design: The MRP-M350 is a Class D amplifier, which operates more efficiently by turning more voltage into useable power, and generating less heat.

Power Supply: The 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.

Low Pass Crossover: The internal crossover is a 24dB/octave low pass filter variable from 50Hz to 200Hz. There is no on/off switch for this crossover, thus it is constantly active.

Subsonic Filter: This amp utilizes a 15Hz subsonic filter to eliminate super low frequencies that can rob power and damage speakers.

Bass EQ: The Bass EQ circuit provides a boost of 0-12dB at 50 Hz.

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

RCA Cover: The amp comes with a plastic cover that protects and insulates the RCA connections. Two supplied machine screws attach the cover to the amplifier.

Inputs and Outputs

Left Side Of Amplifier:

  • GND (ground): Gold-plated terminal strip, 0.33" wide
