Ok I want to add a Sub and amp to my stock Bose system. What I was wondering..

What do I need to do about RCA cables? I know the system already has an amp...but how is it wired to the headunit? Can i just swap it out?...I have a splitter that taps into the speaker wires and makes an RCA out..but I'd rather not if I can. Does the stock already have RCA outs? If not...how hard would this be that I need to do? and what would I need to do? Ideas?

 

depends on the amp you're installing. PG has a LOC. check ACPs thread about PG Octane amps. Xtant also has something similar. If you don't want to spend too much, go with PG. If you want the ****, get Xtant. There's other ways, these are the 2 I've done.
