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

this amp works very well. it stays cool and the power output is amazing it you bridge it to 2 channels. it had very nice sound quality and stereo imaging was great. very easy to handle power requirement too

This is a powerful amp and the sound quality is outstanding. You can't go wrong with this amp. Class d amps are the way to go they run cool and are energy efficient. Have a small foot print, with a very good fit and finish and like I said sound really good. This recoil embodies all the qualities you look for in an amp. The di550.4 is an 80 watts × 4 amp. 95% SNR. But in the recoil DI series line up you can get far more power so choose your need. For me 80 x 4 was more than enough. Now I have a separate powered subwoofer and I'm using a two farad capacitor to drive both amplifiers to get the most out of them. I used this to replace my crunch audio pzx900.4 a/b class amp. Which gave me good service for more than 12 years and I'm not sure altogether that it's still not working I just decided to replace it. Next I will replace the capacitor which is also over 12 years old I won't need to go larger I'll stay with the two farad and just replace the one that is still working but it's time to replace it. With me my stereo is like my friend and if I were to sell my car I would remove my stereo and put the factory one back in, I would take my friend with me to my next car. My head unit is a dual din Kenwood Excelon. I love the kenwoods and I use them exclusively. Go with the excelons and you got the best they have. This amp represents a great value at its price point, can be found for under $90.00 but beyond that it's a best buy in my book. Look for the utube reviews. Recoil for serious sound.

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🏆

Excellent quality amp for the price. I bought this amp to replace the Boss 4 channel amp that had a high pitch noise. I am pleased that this amp has no signal noise and works perfectly. If I put together another sound system...I'm definitely buying this amp again.

love this amp. it kicks my 4 300 watts 6.5 skars and tweeters. is very loud and it doesn't even get warn. I would highly recommend this amp.

Powering two 6x9 and two 5” mid/subs in a Jeep TJ.. use a 4g wire! Thing bumps, driving with the top down at 50mph, sounds good. Very happy w my purchase. Initially I had a thinner power wire and ground, too close to the RCA cables, bad whine in the speakers. Separated the power from the RCA routing to this amp and it’s fine! Good deal. Only had a couple weeks, I’ll update if it doesn’t last long this summer.

The fact that the first one I received was D.O.A. I mean nothing worked, no lights or anything. So I proceed to do all the test to verify it wasn't some mixed up something or another. Then called Amazon and bam another one was at my door the next day! No big deal. Right? The next day i installed the 2nd one and at first I thought it was all good. Got it all hooked up and set all my gains with a osilascope so i knew everything was good. That's when I noticed that the front right channel wasn't putting out the same power as the front left channel. So I checked the rear channel and the rear left was only putting out half the power as the rear right. So I shut it down and double check everything was good and all my wiring checked out. Then I turn it back on and the alarm light was lit and wouldn't turn off. I tried everything ( new fuses unhooking everything but +/-/remote turn on, still red alarm. So I called Amazon again and returned it. What are the chances that I got 2 duds in a row. I mean come on. Manufacturing and Q.C. really must be having a bad day or is just non existent. There is a reason why it's so cheap. Do yourself a favor and spend a little more on a name brand amp or keep trying the budget option and kicking yourself in the butt for doing so later...

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.

kompakt, passt gut versteckt hinter die Konsole und gibt den kleinen aber kräftigen Lautsprechern deutlich mehr Klang.

Cioè va bene ansi va benissimo . Ma i Watt non sono quelli dichiarati . Per il sub in breadge non li rira mai i 240watt di RMS ne tirerà fuori massimo 150 .... forse .

Pros: Doesn't get hot. Powerful. Goes loud. Cons: Sounds harsh, and becomes strident and very sibilant at higher volumes.

Shocked how well this works. For the price and just in general. Have it running my 4 kicker 6x9s in doors and my 4 inch dash speakers. Have it paired up with 2, 8 inch Memphis Mojo's in a mojo box powered by 1500 watt Memphis amp. In my Ram. Sounds clean and loud. Best setup I've had so far.

Es arbeitet super und passt gut in den Polo
