Our take on the Alpine MRV-M500

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

Compact powerhouse

Alpine makes it a little easier to get great bass in your vehicle, especially if you drive a compact car. Their V-Power Series MRV-M500 mono subwoofer amplifier sends up to 500 watts RMS to your sub, guaranteeing some powerful bass on your drive. And Alpine made this amp so small — it's got less than an 8" by 8" footprint and it's just over 2" tall — it can fit almost anywhere.

Thermal protection without annoying shut-downs

The MRV-M500 uses a technology called Enhanced Shutdown Performance, which rolls back the output a bit when the amp threatens to overheat from playing at its limits too long. Instead of shutting down completely, it continues playing your music, until it cools enough to return to full power.

Convenient features

A low-pass filter puts you in command of the frequencies that reach your sub, while a bass boost lets you apply plenty of low-end punch. The amp includes preamp- and speaker-level inputs, so you can install it in almost any vehicle, even one with a factory radio. If you're using the speaker-level inputs, the amp senses an incoming signal and turns itself on, eliminating the need to run a turn-on wire run back to your vehicle's receiver or fusebox.

If you're a tweaker, you'll appreciate the end-piece terminal covers that can be snapped in and out without the need for any tools. You can control the volume of your MRV-M500 from the front seat with the optional RUX-KNOB remote bass controller.

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured with 1% or less Total Harmonic Distortion plus noise (THD+N) over a frequency range of 20 Hz to 20 kHz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. Using CEA-2006 criteria, the Alpine MRV-M500 is rated as follows:

  • Power Output:
    • 4Ω: 300 watts x 1-channel (<0.2% THD+N)
    • 2Ω: 500 watts x 1-channel (<0.3% THD+N)
  • Signal to Noise Ratio: 85 dBA (105 dB at rated power)

Speaker Level Input: A speaker level input harness is included, making it easier to add the amplifier to a factory radio or to a receiver with no preamp outputs. The 8-pin harness has inputs for front and rear speakers. While only two speaker inputs are necessary, wiring all four will minimize the fader's effect on the subwoofer output.

Auto Turn-on: If using the speaker level input, an automatic circuit turns the amplifier on when it senses an input signal.

Low Pass Filter: The amp is equipped with a 50-400Hz variable low-pass filter with a slope of 24 dB/octave. This being a mono subwoofer amp, the crossover is always engaged.

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

Wired Remote: An RJ-25 jack is provided for connecting an optional RUX-KNOB wired remote (item number 500RUXKNOB, sold separately), allowing remote control of the output level of the amplifier.

Connections:

  • Battery: set screw terminal; accepts up to 4 gauge wire
  • Remote: set screw terminal; accepts up to 8 gauge wire
  • GND (ground): set screw terminal; accepts up to 4 gauge wire
  • Speaker Output: set screw terminals; accept up to 8 gauge wire
  • Line Inputs: 1 pair of stereo RCA jacks
  • Line Output: left and right channel RCA output jacks to daisy-chain another amplifier without having to run an additional set of cables; the output is not affected by the MRV-M500's internal crossover
  • Speaker Level Input: Molex plug input for supplied 8-pin harness
  • Wired Remote: RJ-25 jack for optional wired remote

Note: Alpine recommends 4 gauge power and ground wire (minimum).

I've been running this amp for almost six months now and its holding up perfectly. It is really efficient even compared to other class D amplifiers. I was originally powering a pioneer tsw-304r with it at 4 ohms but switched over to an Obsidian Audio 12v3 at 2 ohms. Works great with the new subwoofer as well.

Best Amp for the $

Written By xpgdeadone, Portland OR. on Wednesday, March 05, 2014
 
By far The best amp I have ever owned. I had to add my review after reading the 2 reviews that only gave this 4 stars. For one if your digital Alpine amp is getting hot you need to learn how to install an amp as its digital it doesn't draw much heat to begin with. Then to the guy that says its just ok. You sir need to learn how to adjust an amp and realize its pure watts not the garbage you get in most amps.
Pros:
Everything.
Cons:
none

Powerful Compact Affordable Amp

Written By B, South Florida on Saturday, August 31, 2013
Crutchfield Customer Review (What's this?)
 
Bought this amp to power a compact kicker 10" speaker rated for 600 watts. Alpine always rates their amps below actual output so although rated at 500w the actual test page that comes with the amp shows an output of almost 570w. The amp more than produces. Sounds great. Has enough adjustments on it to refine the sound without breaking the bank. Love the remote bass knob as well, it's a must as you can control the level from the front seat.
Pros:
Great price, Compact, Puts out ample power, Accepts Alpine Rux Knob.

Alpine impresses again

Crutchfield Customer Review (What's this?)
 
Alpines amps are amazing and this model is no exception. It produces clean power to the subwoofer right when it needs it most. I installed this amp right under my seat in my 2008 tacoma and it still has plenty of room to breathe. This little amp packs a big punch! I recommend this to anyone looking for lots of efficient power in as little space as possible.
Pros:
Size. Response. Efficiency. Ease of installation
Cons:
None so far

Installed the MRV-M500 with the RUX knob. I'd argue the Rux knob is a must for instant gain control of the sub. It's powering two Polk DXI104's in parallel . Sounds tight and clean.

Amazing

Written By Dcline15, Edwardsburg, MI on Saturday, August 17, 2013
 
This amp can deliver. Each amp that alpine sells comes with a little card that tells you when it was made and how much RMS or power it was putting out at the time of testing. I have had this amp for awhile and I am not suprised by the results. Alpine is a true brand you can trust and has and hopefully always will be. This amp is only rated for 500 RMS but the sheet that came with it said it was putting out 566 RMS. And i was surprised that they said it could really put so much out foe being so small. So i went and had it tested, the amp really put out almost 600 RMS. Which is just amazing. This is just one amazing amp I would recommend this to anyone who wants to have a cheap but reliable system in any vehicle. This amp is small and can be put just about anywhere you need it to go, under your seat or behid a bench seat or even right on the box. Where I have mine at is right on the side of my sealed box. This amp is small enough to were it will fit right in the wedge part of it. I give this Amp all 5 Stars!!!
Pros:
Small Powerfull Sleek Futuristic Clean Easy to hook up and tune Solled its heavy but not to heavy but it still feels like you can toss it around and will hold up to wear and tear for years
Cons:
NONE!!

Smaller with more power!

Written By Thntx, GA on Friday, July 19, 2013
Crutchfield Customer Review (What's this?)
 
Well, Alpine has delivered once again. A little history first. In my previous car, I had an Alpine MRP-M450(rated at 400w @ 2ohm) and was attached to two 10" subwoofers. The sound was awesome, it fit nicely under the driver seat and the power was great. After many years of service I had to say goodbye when the car sold. Fast forward to the new car and the new Alpine MRV-M500. Space was even a bigger issue as I did not have as much room under the seat as I had in the old car. The MRV is almost 40% smaller. So, it fits! It's also rated at 500w, nice increase for sure. Also, the price was the same as the old one was 4 years ago. Are you kidding? It is powering two Polk DXi 104s and it hasn't broken a sweat. 140+ dB at the windshield. Sound quality is what you would expect from Alpine: nice and warm.
Pros:
Plenty of power, great sound and good looks.
Cons:
None!

Written By Travis, Arizona on Thursday, July 18, 2013
Crutchfield Customer Review (What's this?)
 
Have this powering a pioneer 10" shallow sub in a hidden .65cf box in my VW GTI. Rated at 500w RMS @2ohms, but mine came with a certificate certifying it at 576w RMS, not bad! Running at 4 ohms it should be a bit over 300 RMS, and its more than enough good, clean power to keep a smile on my face with all types of music. Oh, and its tiny too!
Pros:
Price, size, looks, rux knob compatible, but most importantly, sound!
Cons:
none!

The perfect amp to supplement speakers powered by a head unit only. Running it at 2ohms driving 2 SWE-10S4's this thing isn't breaking a sweat. It doesn't even get warm. The compact size made it easy to mount, and it easily accepted my 4 ga. power and ground wires. The blue light is pretty cool visually. Bottom line, this is a great amp to balance out the bass.

Great, efficient amp!

Written By DLW, Mansfield, TX on Sunday, April 28, 2013
 
Alpine continues to impress! This amp's footprint is so small that it allowed me to mount it on the side of my under-seat enclosure in my truck, making for a very attractive install. Also, this small amp packs a PUNCH! I've got it running at 2ohms, pushing two 10" Tobys (www.tobyspeakers.com). It sounds AMAZING! The blue square that lights up is neat-looking at night. When driven hard, this amp barely warms up. I anticipate this amp will give me years of phenomenal music.

Plenty of Power

Written By Jason S., Jena, LA on Saturday, April 27, 2013
Crutchfield Customer Review (What's this?)
 
Installed this amp a couple of weeks ago in my 2010 Honda Insight. Hooked it up to a JL Audio HO110RG-W3v3 and it pushes this speaker to the max. Had to wait a while for the subwoofer to properly break in, but now it slams the bass. A must have for this amp is the RUX-KNOB that goes along with it. So easy to give different bass levels for different types of music or just different songs in the same genre. Each of the amps comes with it's own certificate showing how many watts it actually made at the factory before it was shipped. My certificate showed 572 watts and I have no reason to doubt this. I have the gain turned up on the amp and the RUX-KNOB has to keep most of the songs in check so there is no distortion. You would need to buy a subwoofer that could handle more than 500 watts before you start to dial up the bass boost. Even after listening at max levels for about one hour, the amp is warm, not hot. Never had it go into safe mode either. It was very easy to set up, connect and get running. Small size makes it easy to find a place to mount. This amp definitely is worth every bit of it's price. It's power makes me consider the fact that I could hook up a W6v3 and it would be able to push that speaker to the max also. Don't hesitate to get this amp and the RUX-KNOB to go with it. Can't be beat.
Pros:
POWER!!!, RUX-KNOB, small size
Cons:
NONE

Apline, " A+ "

Written By MattS, Richmond,VA on Thursday, April 18, 2013
Crutchfield Customer Review (What's this?)
 
Straight to it, using this "little" amp, w/ 4g power, to push a JL 12w3v2 in a sealed sub enclosure. It rocks out tight crisp bass. Possibly it's my alternator, however, w/ it's 'd' class rating I do NOT need a capacitor. It fits fine under the front seat of my Mazda3i next to the Alpine PDX4.150 pushing my 4 high pass speakers ( JL's C5-5x7's ) By the way, I am using my OEM HD unit w/ the ' Audio Control LCQ-1' line converter w/ EQ , from Crutchfield, and I have no noticeable whine and great sound.
Pros:
cost, efficiency, size, line bass control ( optional )
Cons:
have none

100% !!!

Written By SamS, Maryland on Thursday, April 11, 2013
Crutchfield Customer Review (What's this?)
 
This Alpine 500 watt mono amp is 100% GREAT!! 1st, it is Alpine which is a great company and has been making leading amps and subwoofers since day 1 so you know it will perform well. This amp replaces the Alpine mrp-m500 which is pretty much the same amp, same specs except as far as specs go this one can go up in Hz ( up to 400 Hz ). I dont know why you would need to go that high, but its there if you want to.This new version also has a beautiful sleek design and look to it, but best of it is SMALLER than the Alpine mrp-m500 and LESS WEIGHT so you can insatll and fit this almost anywhere you want. The old version Alpine mrp-m500 is a great amp and i would still buy and use it now. ( it is a little bit cheaper and you get same specs, performance and results ) but if you are tight on space or want to be able to mount your amp anywhere you want, go with this Alpine mrv-m500 as i did.( to me it was worth the little extra money ) You will not be dissappointed! I hooked up this amp to just a single 10" Alpine SWS D4 subwoofer in a 4 dr Honda Accord and it sounds incredible for just a single 10" sub. ( better than my 2 12" Alpine type E subwoofers powered by an 600 watt mono amp in my Audi A6 ) I would recommend this to anyone and I would buy this amp again and again!
Pros:
SUPER LIGHT EXTRA SMALL PERFORMS GREAT BEAUTIFUL SLEEK LOOK CAN BE MOUNTED ANYWHERE, EVEN IN TIGHT PLACES ITS ALPINE GREAT PRICE FOR WHAT YOU GET
Cons:
NONE WHAT SO EVER

I just bought this amp and I've bridged two 10" Alpine Bassline subs so that it sets the impedance at 2 ohms and 500w RMS which is exactly what this sun is rated for. All connections are okay but this amp gets extremely hot and I saw that this amp is supposed to handle the heat pretty well which is why I was very surprised once I noticed how hot it gets. Are the subs just too much to handle? Alpine even suggests using this amp for the their Basslines so I don't see what the problem is. [ Joseph  Jul 30, 2014 ]

  • My amp is connected to a JL W3V3 in the HO box, so it gets run hard too. I have noticed mine gets hot also, but it has never shut off or had any issues. [ JASON A   Jul 31, 2014 ]
Can I connect the MRV-M500 to dual subwoofers? or do I need 1 amp per subwoofer? I have dual 12" subwoofers in a box. [ Clyde  Mar 30, 2014 ]

  • Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy Staff  Mar 30, 2014 ]
I have noticed that since i have owned this amp that it gets VERY warm at times, i dont even keep the gain all the way up yet i have had time where it gets very hot, alot more so than the version of this amp that this replaced. Anyone else have this? [ Rexx  Jan 07, 2014 ]

  • when I first installed the Alpine MRV-M500 in my car, I noticed that about, in the first six hours, it was very very warm, but after that, it has been working fine, I did not do anything to fix it , I've had this amp for five months, and when I touch it with my hands, hardly feel hot and the music in my car listening very clear, I also noticed that the sound of my 12'' subwoofer had a change, now also the sound is strong but does not have much power as punch to make my car shake or vibrate as Previous amplifier that I had, but still I like it because all my music is heard entirely clear.

  • i have never even felt mine get "hot". the only time i check it is during the summer on the really hot day (99-102). have you try mounting the amp so there's a space under? And maybe try an open mounting position, meaning good air flow. mines on top of my box dual subwoofer 12in box. and its taking up the whole back part part of my extend cab s-10. you might just have a bad amp to. one of the main reasons i bought this amp was the fact of its thermal protection.

  • I have this amp mounted under back seat in Chevy truck, so I'm unable to monitor heat, if any. [ WILLIAM   Jan 07, 2014 ]
  • Even though I have a hatchback where the amp can get plenty of air, I have noticed that it gets hot, but has never gone into protection mode or declined in performance in any way. The gain on my amp is almost all the way up too. I'm pushing a JL Audio HO 10" W3V3, so the amp is matched up well. I am not a car audio expert, I just know that the amp keep working with a heavy load. [ JASON A   Jan 07, 2014 ]
