Hi I've got a problem my alpine stereo its only got 2 rca pre outs, I've got two amps, one 2 channel and one 4 channel (driving 6x9 and sub) 2 channel is for my front set up. The 2 channel has some connections for speaker wires as well as the rca, if I use these is there a major loss of sound quaility. Thanks in advance.
