Dropped the glovebox, backseat, removed the changer, unplugged the outputs on the factory Pioneer amp, spliced into the speaker outputs and byassed the amp.

A little over 50FT of speaker wire later, everything works as it should. Deck power sounds identical to the factory pioneer amp, literally sounds the same.

I was in a rush to get to a bday party so I left the factory amp plugged in and powered up - literally the only wires cut were the output wires to the speakers. I didn't have time to experiment to see what happens if I remove the stock amp all together. It seems that the remote on (for the sub amp and power ant controls) are all daisychained through the amp.

Behind the dash, I have the Metra wiring harness adaptor wired up as it should be except no RCA input, 4 sets of speakers going to the back of the car supplying signal to the factory speaker wiring, and a "Phono Jack" spliced into the subwoofer input leads on the car and plugged into the sub out on my HU.

Like I said, works like a champ. Literally the only thing missing is the changer I left out.

In a few months when budget permits 4x 6.5" seperates, and a freeair 10" in factory location with one hell of a multichannel amp running it all will finish this deal up.
