Alpine MRV-F300 4-Channel Car Amplifier, 50 Watts RMS x 4

In my 2000 Audi A4 Avant (wagon) I have a Pioneer 7-inch touchscreen with a 12" Rockford-Fosgate in a sealed box with a Sony 500-watt amp (could maybe be better, but not bad). Then main speakers (RF 5.25 componenet/6.5 coax) were too weak and distorted above 25 while they were powered by the head unit, so I decided to buy my first ever main speaker amp. And I'm glad I did, even though running all the wires was a bit of work. It sounds great. At first, I thought it was too loud, and laughed. I haven't been able to turn it up loud enough to make the speakers distort. It's class D, so it's never overheated, and I don't expect it to. I bought this one in particular, because I wanted to be able to set my high-pass filters higher, but with the higher power, I've found 125/150 sounds better. It looks good. It has a very clean look and is relatively small. I mounted it on top of my subwoofer box next to my sub amp, which is also small. My first main speaker amp, but great in my opinion. I would buy this amp again. Kind of hoping my subwoofer amp dies, so I can buy an Alpine or RF amp.

Basically obligated to give all 5 stars on this one. Purchased from avLeaders a few months ago, ordered the Alpine mrv-300. Got it a few days later and realized they sent me a different amp than I had ordered. Due to having oversold the amp I ordered they upgraded me up the to next best thing. An S series s-32F. Which over the mrv 300 the slight changes are great. Stays luke warm under heavy use. Havent had any over heating issues or any issues so far. I have 2 x Rockford punch 6.5s and 2x Rockford punch 6x9s in channel 1 and 2. And a Rockford prime 10in r1 sub in bridged on channel 3/4 with the Alpine sub dial. Handles everything like a champ. Used knuconcepz 8ga amp wire kit.(beware 60amp manl fuse included.needed 40) was nearly surprised how well it pushes it all. For my music it sounds just fine. Just remember to set your gains properly. And match the speakers RMS wattage to within 100%-50% of the amps per ch/RMS. Never go over. A bit under is fine. Thanks AVleaderz you earned a customer!

Fairly straight-forward install. Main drawback are the set screw terminals. fork terminals would be more secure. Other than that, this is a quality, powerful amp. It's installed in my 2018 mazda 3 non-bose, with focal components up front and morel coaxials in the rear. It gives them a nice mid-bass thump that I can feel through the seats. It's small enough to fit under the passenger seat and it has never gotten so much as lukewarm. The amp itself is virtually silent with no signal going through it, so be sure to pair it with a good clean source. For the power cables, I used 4 gauge cables which just barely fit. They're probably overkill and I would recommend 6-8 gauge for ease of installation. Paired with a PAC AOEM-MAZ2 line-out converter. EDIT: Replace the PAC AOEM-MAZ2 with a LC2i and it sounds even better.

Just had installed for 2 days so far and it sounds fantastic! The fidelity of this amp was very, very good for the pricepoint, design/construction is great and it has an excellent feature set for configuring to the various install scenarios you might encounter. I was looking for something not too expensive to get rid of the nasty distortion at barely audible listening levels I was experiencing with a "high power" aftermarket head unit and this delivers clean, accurate audio with a some extra power on tap to render dynamics! Nice. Just the ticket to breathe a little life into the typical under spec'd car stereo system.

Really surprised on how nice this amp actually is. Has nice power and works well running a set of Boston Acoustic components in the front doors and a set of Alpine Type R 6x9's in the rear of the vehicle. My only dislike about the amp is that I feel that a cleaner wire attachment arrangement could be made. Even with the semi useless covers over the wires to supposedly finish everything off you still have an unsightly gob of wires sticking out of both sides. Definitely an amp that would benefit from a custom install with custom finish plates etc. Still, so impressed with the sound and usability of this amp that considered buying a few more for my other vehicles.

I've been doing car audio for a while now, more of a hobby than a career choice however. This was purchased to finish out the system in my winter car(1997 jeep ZJ). I finally got around to replacing the factory amp recently with this(mrv-f300). I have all Alpine drivers in the doors, components up front, coaxials in the rear doors and everything in the jeep was sound deadened. I have a aftermarket head unit, and with the rms I was pushing in my cargo area(also alpine), i really need to tighten up my front stage and mid bass. Yes, this car can get rediculously loud, but honestly I tuned it for SQ and rarely blast it unless there's someone else at a red light that thinks they're kool. This amp matched up with my door speakers beautifully and I couldn't be happier. I'm literally about to buy another one for my daily driver. Everything is adjustable if needed, and since I'm using it for full range and this is upstream of a crossover network, I just set it to full range and my gains were already nominal. Just remember when you're EQing, it's better practice to cut harsh frequencies rather than boosting wanted ones, it really does make a difference in your final sound stage as a whole. I'll post pics of it, not that there's too much to see because it's quite small. UPDATE: I did in fact buy another 2! One for the Baja and one for the Jeep. New pic attached. It fits perfect under the rear seat of the ZJ, and for all of you who have existed in the world for a few years, at some point in time have seen a older model Jeep grand cherokee, so this should give you an idea for size.

Great product. Not as high-end as their older PDX line, but it makes its rated power (and then some) according to the birth sheet, it has high build quality, looks nice, runs cool, and has a small footprint that offers great installation flexibility. I have it running my 4 3-ohm 6x8s (1 in each of my 4 doors), and though it's a class D, it sounds great. Some people swear by class AB for mids/his. I'm very satisfied with the sound quality of this amp, however.

I have 2005 Acura MDX with Navi and with Bose. It’s hard to run new speaker wires in this car, Acura makes their interior almost to good. But I made it work. This amp fills the car with crisp highs and mids and has the potential to bring decent lows. But if you’re the type of person who cruises to Hotel California, this is it. I use it to bring the punch out of my JBL GTO 609c in front. The included crossover for the tweeter and woofer worked great. In the rear I used a pair of Kickers. I love this amp, 100% worth the price!

Perfect for a small space, hooked it up to an alpine component system in a dodge reg cab, sound is super punchy and tight now the mids sound like they actually should! They used to just distort when I was running the same speakers off the deck. And the test of the amp I purchased showed it actually puts out 89w per channel instead of the advertised 75w! Great amp for a great price

eL SONIDO ES IMPECABLE, no hay ruidos ni distorsión, mucho menos sobrecalentamientos pues es clase D, Es un producto indispensable para un gran sonido, sub valorado pues luego le damos mas importancia a las bocinas y al stereo y muchas veces la fuente es lo que termina haciendo la GRAN diferencia Es tan puro el sonido que aun y con mas potencia, las vibraciones serán menos que antes de instalar la fuente.

Efficient & powerful, Alpine has never let me down in 35 years.

nice little amp had it for about 2 months now. mine does 97 at 2 ohms not 75 as stated. still have to tune it a little bit but its probably almost 3 times louder than my head unit was.

This amp is great tons of power and small in size. Runs my infinity components rated for 90 watts @ 2 ohms with ease.
