I was to make sure I understand this clearly... I want to power my components with the 2 front channels (4ohms) and bridge the rear for a subwoofer (2ohms). The reason Im asking is b/c i dont know what voice coil configuration to go with and if the front and rear channels can run different ohm loads?
Are you using one four channel amplifier in this configuration. Most four channel amplifiers aren't 2 ohm stable when bridged. You may want to check on that and decide from there.
