bridging 5 channel

Hey guys, I have a chance to buy a good Alpine V12 MRV-F357, This amp is five channel. 30W x 4 + 100W x 1 rms. I do not want to use the 5th channel. So does that power go to waste. I need this amp to drive one set of Polk 6 1/2 inchs dx3065 components and a set of 6x9s Im thinking if the 5th channel power can not be bridged into a set of the 4 channels. THis will not be enuff power but im not sure. :confused: What does everyone think?

Thanks

:p

If there is no load connected to the 5th channel there is no real power being wasted.

Personally I would look into a different amp. If you ever decide to use the 5th channel, 100W isn't near enough to adequately power a subwoofer.
