Can I use a 4ohm DVC sub with a 4ohm minimum bridged amp?

Don't bridge the amp. Keep it simple by wiring each voice coil to a channel. That keeps the impedance match and puts 100 watt on each voice coil for your whole 200 watt experience. You can run 8 ohms on the amp without hurting it, but that's doing it the hard way. If you want to brighe an amp, use a single voice coil speaker on it, not dual voice coil ones.
