POSTED THIS IN AV FORUM BUT GOT NO RESPONSE:

Ok so im adding an amp/sub to my 01 cl. Ive done installs before on other cars, but this one is giving me a headache. I have the stock amp disconnected and everything and now im stuck. Im trying to add a second amp to power 2 10's. I run the power wire from the battery and i splice the ground, etc. BUT, where do i hook up my amp outputs/inputs on the stock amp because i read that you could do that. Ive already checked the DIY threads and im stuck. Maybe Im dumb, maybe working in 100 degree weather isnt smart either, but PLEASE HELP! maybe you could even post a step by step on what to do from here. all i have tto do is hook up a second amp with my existing bose amp. thanks, chas

WHERE DO I HOOK UP THE RCA OUTPUTS/INPUTS?

 

You have to splice female RCA connectors into the stock wiring. There is a diagram in the A/V section.

 

what numbers or wires on the diagram?

 

the ones that are not used? "shields"?
