Sound System Upgrade Information - Standard (NON-HK models)

[unL33T]

If I wanted to put a 4 channel DSP in line, what would be the best way to give it full signal while maintaining fader control? I would think if I just feed it the signals for the front and rear speakers I'd lose bass input to the DSP, no?

Wanting to add 2 speakers to the rear doors. I have the standard stereo, I.e. non HK.

Does the stock amp have rear speaker high level outputs, but maybe not wired?

If so, the amp might auto-detect these 4 new wires and and also enable front/rear fader control ?

From my reading (I have not done it yet), the wires exist from the radio to the doors and the coding needs to be changed to activate them.
