Hi,

Thanks for a good response and suggestion. I do have a Velodyne CHT12 subwoofer (170W) I forgot to mention. So then answer is the preout is just a passthrough and will not ultilize the receiver's 100? speakers will only get 200w from the power amp.
Sound like I either need to get a power amp or higher efficient front speakers. I've looked at the power amp and man they're expensive. Though I listen to music very loud. I've also watched surround sound movie a lot, so do I really need to get the 5 channel or just a 2 channel power amp (5 channel will cost me arm and leg if I don't really need it)? Since the 2 front spearker are the only 2 got "hit" the most, what I was thinking to do and please correct me if I am wrong (or not a good thing to do) is to buy a 200wpc 2 channel (stereo) power amp. Hook this power amp to the pre-out front left and right (yes I do have pre-out on my receiver) from my receiver so that they can push out 200W to the front speakers. Hook up the center and 2 rears to the receiver as they are right now (these 3 will on get the "original" 100wpc). Will this work? Does it harm the receiver/speakers at all? Will the sound be out of sync (being that they're not coming from the same "device").

I'd really appreciate if you can answer these questions.

Thanks a lot for your help.
