I'm just wondering, can I take a 4 channel amp and use the 2 front channels to power 4 4ohm speakers, and use the 2 back channels to power a sub?
Obviously i would need a 4 channel amplifer that would allow for different cut off for the front and back. Is there anything else I should be aware of if this can be done?
Is there anything you would recommend? I'm trying to do this cheap.
