Audio Systems: jbl amp wiring, signel, anps

Question
do you have the wiring schemactics for this set up trying to add bigger anps to my 92 tbird sc I thought about using the speaker wire output from the  factory amp into my aftermarket kenwood amp but cant figure out the color coding for the wires

Answer
Hi Rick,
Don't retain the factory amp. replace it as a swap out.
You cannot use the high power speaker wires from the factory amp into another amp unless it has hi-level inputs and that would be from a head unit anyway, 40/50w per channel, not another amp, 100/150w per channel!

Discounect all speaker wires, using an AAA battery (nicked from the TV remote for an hour), touch two wires one either end of the battery and listen for a crackle, mark that pair to identify the speaker and go fo the next pair.
input to the amp is simply 12v from the battery via a 40a inline fuse. earth to chassis and 12v signel from radio when on.

Colours I cannot help with as it's an American car and as you can see from the way I spell colour I'm not ;-).
Good luck, Peter
