Bi-amp your front speakers, which will double the amps to the fronts. Read the manual on how to bi-amp. You'll need front speakers with 4 speaker wire jacks instead of 2, which are on there for bi-amping. Bi-amping takes a spare channel, such as the rear surround and adds the channel to the fronts. This method separates the tweeters from the mid/woofer drivers, and for me, it sounds a lot better. You'll still have 5.2, with two fronts, 2 surround speakers, a center channel and 2 sub-woofer jacks.
