So I have a 2007 grand prix Gt with onstar and monsoon. I finally got my wiring kit for a aftermarket stereo but the speaker wires on the kit are RCA plugs and the speaker wires on my deck are just regular wires... this creates a problem for me... can I just hook up RCA Connections to the regular wires and plug them into the RCA connections on the aftermarket wiring kit I got or do I need some kind of new wires?? Please help I've been without my system for two months and im starting to have withdrawls
