I have an 02' Sport trac and was wondering if the RCA interconnects from an amp wiring kit will plug directly into the factory single cd head unit or do I need some sort of adapter? Thanks
You will have to get speaker level output, which will tap into your speaker wire for a signal. Depending on what type of amp you are running, it may or may not have speaker level inputs.
they make signal converters and you can get them at Circuit City or any auto radio place. they are a box that u wire into a speaker wire and it changes signal to RCA outputs. then you plug in some rca wires into the little converter box and to your amp. their like 19 bucks. cheap.
I recommend avoidng the converter and going with an amp that will take speaker level inputs. I had many turn-on/turn-off pop problems caused by two different converters with the 2001 six disc head unit. On advice from a local car stereo shop, cured it by going with speaker level input to the amp.
