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

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 bought this amp for my 14 Silverado that has an aftermarket android with all new mid grade aftermarket speakers and this thing is loud I replaced a old Alpine 4 channel with this one big difference in sound quality believe it or not if you're looking for an affordable nice 4 channel amp this is it it's small powerful and it runs cool even when I have it cranked for awhile and it's inside my center console plus it's easy to adjust for sound quality

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.

Update: almost a year of use later and no issues with this amp. Used daily mostly at normal listening levels. But everyone in a while I crack up the volume to max and this thing just works. Wish I bought a spare but it seems OOS now.Needed Something that would fit in my factory location and deliver close to 100 watts on a budget. Tried the taramps and they proved unreliable. This amp looks decent and puts out decent power.Only complaint would be the spade terminals. Would have preferred the hex screw type but you can't always have it all. It was good enough that I considered getting another one for backup. About 2 or 3 months of use so far and no issues worth mentioning

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..

i have had this amp for about 10 months now and it still continues to blow me away. it is everything i was hoping and more. the bass it produces is simply incredible. my entire system is recoil products, i am using this amp to power a recoil RW8D4 subwoofer, recoil REM65 component speakers, and recoil RCX65 coaxial speakers and it has all the power in the world and still a ton of overhead left over. i would recommend any recoil product to anyone. i have had absolutely zero issues and every day i am blown away by how great everything sounds. multiple friends who have spent a substantial amount more money on their system, mostly due to shop install versus doing it myself, but also their gear like memphis audio, sundown, jbl, ya know the more "1st class" gear everyone knows about, but even they were either pissed off because they spent so much to get a less end result, or they were just blown away by how good it sounds. im telling yall recoil is a fantastic company i have had absolutely zero issues since i installed myself. not one single time have i ever lost audio or have never had to remove trim pieces to fix something at the speakers. everything has just worked and worked extremely well

Had it installed for a week already and no complaints! Sounds really clean on my speakers. Would recommend!

Good solid amp
