[QUOTE="mikelaubach, post: 7344322, member: 632557"] Ned the manufacturer and model of the current radio to tell you anything that will help, as Benz said. Now here is why, use this to learn: Some radios have sub-output RCA's in addition to "full range" RCA outputs. If yours has both, you WILL need to get behind the radio (ie - you got's to take it out) to see if it is installed in the sub-out port. The full range output RCA's will allow you to connect the RCA's to the FIRST amplifier (the door speakers) and then run the output of the first into the second amp (the sub amp). Most likely, the output from the sub amp won't be full range. So you can get away with using only one set of RCA's that are already installed, but ONLY if you use the full range output RCA ports, and run to the door amp, then the sub amp. As for wire to the door speakers - RUN NEW. Don't use the factory junk 16-18 gauge (skinny) wire. It will be a headache trying to splice into it, and it will cause you untold headaches down the road when those connections get loose, or corrode, or whatever. AND it is EASIER to just run new wire! Good luck. [/QUOTE]
