Hope this helps.

 

there are no pre-amp outs, but you can use a line level converter to run to the amps.
I've had issues with multiple amps causing noise on the FM radio, so you may want to just power up the amp before installing it to see if that's a problem. In which case you may want to put a power switch on the amp (what I did) or replace the head unit - which may disable your clock & such.

Good luck.
