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

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.

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!

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.

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.
