Anybody know anything about Car Amps?

Okay..

I bought a really really nice JVC receiver and come to find out, its does NOT have RCAs in the back.. >.<

My amp has "high-level inputs" (im guessing that means the speaker things)
So can i use two RCAs from the amp, cut the other end off and splice them on one of the "rear speaker" wires from the receiver?

Are RCA wires those with the copper wire sticking out that you have to twine into the red and white holes? If so, I think that'll work out. Make sure the output from the receiver is the same kind of audio your amp can process. :D
