For Christmas, I bought my son a Sony DSX-A415BT. It has 2 set of pre-out, 1 for left and right speakers and 1 for a subwoofer, which doesn't allow to fade from back to front. For speakers, I got Hertz Centro CPK165 components for the fronts and Hert HCX 690 for the back. Pushing them with a Rockford Fosgate R300x4, which is 50 watts per channel at 4 ohms, AB amp. The speakers are underpowered by 50%. I was kinda lost about the whole car stereo, but I went for Black Friday deal. I got a Rockford Fosgate Punch 3 sub and a Rockford Fosgate r500x1D amp, which is a D class amp, again underpowered. Being short on funds, my son paid 50/50 on the install. It sounds great. So much better than stock. It made him smile, hell it made me smile.
Some say an AB amp sounds cleaner than a D amp( as in the amp that drives the speakers). But the D amp offers more power and not much more money. Right now my son is smiling ear to ear, but can we get a cleaner sound, bigger sound stage for a little more money?
At the time the car is not struggling from lack of power as in amps. Just a little dimming of the headlight on a hard bass hit
