can anyone help me install a amp in my 2007 ford fusion?

Question

the problem is i dont have the 6x9s in my rear deck to tap into for a signal. and im trying to avoid removing the door panels.

Answer 1

You'll should be able to catch the speaker wires inside the cabin, at the base of the "B" pillar where they run up into the rear door. Alternately, you can tap into the speaker wires behind the radio itself.

I can't find a listing for your speaker wire colors; you can try these, but they may not be correct:

LF+ orange/light green
LF- light blue/white
RF+ white/light green
RF- dark green/orange
LR+ gray/light blue
LR- tan/yellow
RR+ orange/red
RR- brown/pink

Accessory (to tap for amp turn-on) black/pink or yellow/black

Heinz: when using an amp with speaker-level inputs, or using a line-out converter, you'd routinely tap into the factory speaker wiring. Often the easiest way to get to the factory speaker wiring is to get to the factory speaker terminals (though that's not the case in this car, since the speakers are in the front and rear doors).

Answer 2

Just based on your question (one doesn't tap into a speaker for a signal!!! it's an output device), my advice, have it installed by someone who knows how.
