I have an MTX 404 that will supply 200w rms bridged. Can I bridge the front to one voice coil and the rear to the other (400w)? Obviously I would need a dual 4 ohm sub. TIA.
4 channel amps weren't designed for subs. They were meant for powering your fronts and rears. You CAN use it to power your DVC sub but it is not recommended. Powering each voice coil separately will easily damage the sub if you ever have a spike/surge in one of your channel.
