Thx for the input guys. I think I'm narrowing it down now. The plan is one 13W7 or 12W7 (depending on how much diff. there is) powered by a Ti800.1
As for the front, 165W's powered by 500.4 (bridged). Any comments on the front setup? Is a bridged setup not as good? Is there enough power from the 500.4 (rated at 250x2).
Again thanks for any input.
