Pioneer is the best.
Do you still recieve any unwanted sound over your subs? I did.... I had to put a ground loop on the RCA connection. That solved everything.
No.. Hmm. I am actually amazed at how smoothly everything went- voltage regulator works, no speaker pops/cracking.. nothing.
I dont plan on changing out any speakers or installing any additional subwoofers or amps. I am actually pretty happy with the stock sound!
I agree! Even for being stock, the speakers sound amazing with the D3.
