No, you will want to get a class D mono block for a subwoofer amplifier.

I have been frustrated trying to track down the background noise on my headunit. Here is what I have: Headunit - Pioneer 9400bh Amp 1 - Kenwood 150.2 Amp 2 - Kicker 500.1 #1 The pioneer when playing a 0 bit track has pink noise from usb and cd. Kenwood amp is powering my front stage and the pioneer is for the back. Fader front and rear both produce the noise with and without both rcas. #2 So I reattached the original headunit and there is no noise with the 0 bit track cd. It is hooked up to just the rear speakers. I have changed the grounds on both amps, changed the ground on the headunit, done the pico fuse fix (wire wrap). I am at my wits end, please tell me if buying another headunit will fix this!
