What brand and model amp do you have? Does it have speaker level inputs? If not you are going to want to use a line output convertor. I rec. the N-85V from www.davidnavone.com

If you can give me the model number, I can find the manual, and then see what inputs are for what channels.

Personally, I would consider rewiring it. Start with the 4 or 8 awg wire, rcas etc

u mean runing and changing all the existing stock wires rcas front the head unit RP.but i intend to keep the ex amp.the new amp is meant to power the front and sub only.

Well without any info on the amp, I can't really tell you much. I can tell you this though. You will get better sound quality if you use the NE-774V from www.davidnavone.com
