do i need to buy a new cd player so i can connect my amplifier because when i check it out the stock PIONEER cd player ididn't see any RCA connector...

 

Depends... if your amp supports it, you could tap into the rear speaker wires and use high level inputs. Or... there are a couple adapters out there to provide a set of RCA jacks... I think JL makes one?

 

Pyramid makes a cheap one. I have seen it for $12, Have to tap the rear speakers though.

 

Whatever HU you get, make sure it has front, rear, and subwoofer RCA outputs so you can upgrade in the future if needed....

a Line Level Converter will tap into your standard speaker wire and give you RCA jacks if you want to keep the stock radio..
