I actually bought this to replace my Pioneer D-class 1200w amp. The sound coming out of my speakers sound soooo clean, and powerfull. I have this installed in my 8th Gen Honda Civic (without a 2nd battery) but I do have this paired up with a Rockford Fosgate Digital Compacitor. All of my speakers are Rockford Fosgate full-range 6.5 speakers, but I also have tweeters installed (Pioneer). This amp doesn't seem that it sucks up too much energy from my battery, which I was aiming for. I had that issue with the previous amp I mentioned. I went with this amp also because I used to have a mono amp that drove a sub box I had, so I knew what it could do (I now have a powered sub installed in the spare tire. I wanted my trunk space back lol). But IF I needed to buy another one of these, I would. ## Features - The R2-500X4 full-range class-D 4-channel amplifier (1.9" x 6.8" x 10.1") is packed with features and performance to deliver power and bass on demand with 500 Watts of RMS power - Class D technology makes this amp extremely efficient by reducing demand on the vehicles electrical system (RMS Power: 75 Watts x 4 @ 4Ω OR 155 Watts x 4 @ 2Ω OR 250 Watts x 2 @ 4Ω Bridged/Mono) - Featuring C.L.E.A.N. circuitry to help you adjust your gain settings, a P.O.W.E.R.
