Installed this amp today. . . . . Absolutely no complaints so far. I have it powering a set of infinity kappa components. . . . . Loud and clear. This is a very powerful amp and sounds very nice. I am sure with a little tweaking as i break it in it will only get better. Amp does not run hot. . . . And pretty cool that it is the same size as the other amp i installed rp 2000. 1 d. I had been thinking of ordering skar gear for my ride for some time now. . . . . Wish i would have ordered sooner.
