Yeah, I thought that too but didnt know if it would work. I have some older Boston Rally RC41's (4") sitting around that may work. I do have all RCA's going to the amps, so those internal wires should work... huh? I'll give it a shot when I start doing all the install in the next couple weeks. Wont be true center channel, but maybe help with the sound stage. Heck, its probably gonna sound perfect even without it so I'll try it with just the new door speakers first, then see where I'm at.
