Car hifi manuals

If you can't locate them, I could walk you through it.
It would take a complete description of your current system and what you hope to achieve, if anything.
High quality pics of all amp connections and controls followed by a phone call.
Having done several thousand installs, I have pretty much seen everything, but with 6 channels and internal x-overs it gets a little complicated, but definitely do-able. Let me know
