nah, you wouldn't want to do that. for one it wouldn't power the subs well in the first place, and second, you want a monoblock amp for most applications where there are more than 1 sub. Sure, a 2 channel bridgable amp will work, but considering 4ohm subs are the most common, you wouldn't be able to wire 2 4ohm subs to a bridgeable 2 channel without sacrificing power or without causing an unstable amp.
Go get a mono block and set it up right. you'll get the most out of your subs and amp without the fear of overloading anything, or having an underpowered set-up, which usualy is the cause for most subs blowing, not overpowering.
