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

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

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 .

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.

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🏆
