    No. You can bridge two channels. You can't bridge all four together that I'm aware of

    You could bridge the amp to 2 channels and run one channel per voice coil but unless you are extremely accurate with gain matching, you'll end up with poor sounding bass at best and at worst, burnt coils and/or amplifier.

    I would consider finding a decent monoblock amp for your sub. Also, peak power is an irrelevant number.
