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

Used this amp to push 2-6.5” and 2-4.5” skar audio speakers in my jeep. And I can say it has the power and the sound quality is great compared to the bigger brand named amps. I used this to replace an old 1000w 4ch alpine amp. And fits perfectly under the steering column in a jeep TJ.

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.

I picked this amp over many others in the field for the following reasons: 1) Size - I had a very specific install location and this is one of the few options that would physically fit. 2) Signal to Noise (SN) Ratio - This device claims to have a 95db SN ratio (for reference, CD quality is about 104db SN and anything less is going to be less than CD quality, but remember you are in a CAR so anything over 100 SN is hard to tell while driving). 3) Price and delivery - I preferred another amp but it is backordered so decided to give this one a try.The install went well and the unit worked just fine out of the box. I'm glad that after an hour of heavy burn-in testing, it was warm and not hot to touch! I had no trouble pushing 4 component sets of Alpine S2s hard. I dare say the power is as-advertised from a small class D! The combo RCA inputs for high/low power are bizarre. If you wanted to use this for high power, you would have to sacrifice some RCA cables and rig up the inputs to make this work which I'm glad I didn't have to do. I was using low power signal level inputs, but if I wasn't, that would be a big show stopper and I'd throw it down to 2 stars and suggest an amp that has wiring for hi level inputs ready to go.95db SN ratio it isn't though. There is present hiss from the speakers with no source which is a sure sign of overrated SN and THD. I have a dead-quiet EV that I'm using it in. But again, at the price point, I'm reasonably pleased with the purchase and think it is still a good value. For the SN deficiency and the hi input strangeness, I'm going to subtract a star. I would recommend and buy it again for any non-luxury vehicle that isn't dead-quiet inside.UPDATE - The literature that came with the amp says it is 85db SN. The value in the posting is INCORRECT. At least my ears weren't deceiving me.

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 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

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 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
