Recoil DI550.4 Full-Range Class-D 4-Channel Car Audio Amplifier, 1,040 Watts Max Power, 2-4 Ohm Stable, Mosfet Power Supply, Bridgeable

Outstanding little powerhouse mids/hi amp. I replaced my old worn Prime 4 ch A/B amp with this little beast and I'm impressed. Gains are turned way down, and this amp makes my Hertz Unos come to life. Incredible power and clarity from a Class D unit. Incredible value for the clean signal and power this amp delivers. No noticable hiss or distortion what so ever. Recoil for the win🏆

Wanted an amp for my SxS. Though I wasn't familiar with the Recoil brand, I'm glad I took a chance on it.Sounds great with the Noam 5.25 speakers I bought and now I can listen to tunes while riding around doing yard work or just riding around for fun.Fit perfectly in the front storage compartment of my Uforce 800 SxS.

Great 4 channel amp. I have it on my vehicles stock speakers with gains set above half. I use the high pass filter on my head unit to filter 125hz and below. The stock speakers get loud and clear. They would blow if I allowed the lower frequencies through. My volume on 16 is all I can take. It’s loud and I like loud! I recommend this amp it runs cool and provides power.

I did my research before purchasing, and people were getting higher numbers then the rated power. So that’s absolutely a plus considering most of the amps on here even the “best sellers” don’t even reach 25% of their rated power.Pros: very small footprint considering the output power. Good power, no lack in sound quality, very reasonable price, looks very nice.Cons: all spade connections, different setting for channels A and B.My “suggestions” (I guess?) I REALLY wish both channel A and B had matching frequency filters. I believe A caps out at 200Hz and B caps out at 750Hz. It would be nice if BOTH could be adjusted to 750, considering I wanted mine set at 500Hz on both channels. Hens the passive RCA filters on channel A..I thought it was weird that the positive terminal was on the inside rather then the outside, all the amps I have or have installed the positive terminal is on the outside. I may have had to go into my fuse drawer for a couple 30amps because I’m a creature of habit. Not really a complaint or suggestion, more of a “hey if you’re reading this check before you wire”.But overall, I am extremely happy with this amplifier. It has a MUCH smaller footprint then the old Alpine amp I was running, giving me space on my amp rack for more stuff in the future.I plan on purchasing a recoil monoblock in the future to give that a shot, and I’m very excited for that too!

Outstanding little amp.. running jbl components and 3/4 channel is bridged running jl 10w0. Impressive for a such a little amplifier and what's funny is this amp is identical to the Morel mpd 4.70. Same casing, dials, footprint, everything . And the morel is around $240..

Sounds good, got rid of my annoying whine the old amp was causing, and they sent me a new amp when my original 1 had an issue without a problem. Not Amazon actual recoil did.

This is such a powerful little amp,sound is extremely good , I strongly recommend it

Amp ran great for an hour - powered 4 door speakers with one speaker per channel. And of course it happened 2 days past the 30day Amazon return windowed... Dealing directly with recoil support now, spending $50 for shipping both ways to (maybe) repair an amp that cost $90..... My advice is spend a little bit more and get a CT Sounds CT 80.4D amp instead of buying this - depending on how the warranty repair shakes out I'll revise this rating and update the review.... Details below..Amp is used to power four 6x9-4ohm coax kicker door speakers, each speaker is by itself on a channel with 14ga spkr wire. After finally getting the amp installed (the speakers had been powered by the Head unit for about a month) I had it set at about 20% gain. About an hour into a trip the speakers cut out as the amp had blown both fuses. I disconnected everything from the amp, replaced the 25 amp fuses, and reconnected the Primary Power from battery, whereupon the 25amp fuses immediately blew again.I then installed a 4 channel kicker amp with the exact same speaker wires, power wires, and RCA cables in the exact same spot and it is still running fine 2 days later.
