I currently have a mono amplifier for my subwoofer and i would like to purchase another (4 channel) amplifier to run the remaining 4 (5.25") speakers in the car. I would like to get the audio directly from my car computer and not use a head unit. I am assuming that the correct way to set this up would be to get a sound card that outputs 5.1 channels and run one cable (a stereo 1/8" to RCA cable) from the left/right output of the sound card to the speakers' amplifier, and run another cable (a mono or split stereo 1/8" to RCA cable) from the subwoofer channel on the sound card to the subwoofer amplifier. Does this sound correct? This is as opposed to running directly from the left/right of the sound card and using a crossover (either built-in to the new amp or seperate) to split between the two amps. Thanks very much for your input!
