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.

The price is right, and the performance is well worth it. I have the stock sound system that came with my '95 BMW M3 - an antiquated head unit with a cassette tape (no lie!) and an Alpine CD changer in the trunk, kickplate 5.25 inch speakers up front, a mid-range and tweeter in each door, and 4 inchers on the rear deck. The stock amp is tucked into the quarter panel, in the trunk behind the driver's side rear wheel, and this fits right into the same spot, hidden behind the trunk interior panel. Since the stock system has built-in crossovers in the amp, we had to provide crossovers to feed the speakers front and rear. Other than that, seamless installation. I have Bavsound speakers up front and Helix 4X speakers in the rear deck. The stock amp just couldn't push them. This amp drives them to ear-splitting volume. I have added an Alpine PWES8 powered sub (which you can also find here on amazon, I think) and it works well with this setup - not thunderous, hip hop bass but enough to round out the existing speaker/amp configuration.For under $150, its a whole lot of sound upgrade.

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.

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!

Very compact class D amp. For it's price range has good signal to noise ratio, okay rms output @ 50 wrms at 4 ohms per channel and 150 wrms at 4 ohms bridged. Was looking at pioneer 8604 at similar price range which has better output but less signal to noise ratio. Depending if going spl or sq, this is more sq than spl. For my liking as this is subjective on preference, I'd rather have a little more spl than sq as powering my 8" kicker sub bridged at 4 ohms, doesn't push as much as I would want it to. And yes I set the gains and eq on my Alpine amp accordingly to right before clipping to maximize output. But all and all a good amp in a compact form for class D amp for the price.

Great little amp. I replaced a much more powerful Pioneer champion series amp that got super noisy (sounds like ground loop alternator noise but wasn't there when I first installed it) after 4 months. The quality seems better on this one and it is much smaller. Although it's rated for less power, it's definitely as loud and doesn't clip or overheat. I have it driving 2x 6x9"s and 2 x 6" speakers. Two subs are fed by a different Pioneer monoblock. This amp is clean and clear and having two independent gains is handy.One negative is the lack of an RCA output.

Great lil amp.......I got this lil amp to power 4 kickers 2 6x9’ on the rear deck and 2 6.5’s in the front doors and it far surpassed my expectations.small footprint And plenty of good clean power not to mention it stays cool you really can’t go wrongQuick plug for the 3rd party seller avleaderz if your ever shopping and the product is coming from them YOUR GOOD these guys are pretty awesome because of the coved19 situation there’s understandably a delay in shipping even with this and a two week delivery window my lil amp was here literally the next day good lookin out avleaders 👍👍👍
