2 channels can USUALLY be bridged for 1 channel operation *MOST AMPS WILL ONLY PLAY BRIDGED AT 4 OHMS*

so if you wanted, get a more powerful mono amp, or 2 channel amp for the sub (if it needs more power) and use the 2channel for your speakers. (front speakers are always better than rear speakers too)

mind telling us what amp\speakers\subs you actually have so we can recommend somthing?

Yes this can be done by a process called mixed / mono. It employs passive crossovers on the rear speakers and the sub. The rear speakers are hooked up normally to each channel with the addition of a bass blocker of usually a 200-600 uf cap on the + speaker lead to each rear speaker. The sub is wired to the bridged terminals and has a high blocker called a coil on the + lead to the sub. It usually is a 6mh coil.

If the sub gives enough ouput with the amp in bridged mode and no other speakers on it, then I would find myself a small 4 channel amp to power and protect the front and rear speakers.
