lol wow, all this hosility, I do know some things, so i understood the switching the rcas, or well enough to make it work, and i et both points on the 2 ch and 4 and just agree that its prolly best to buy the 4, only use 2 as to not have to rewire them later and then if i choose not to put in the mid bass or second comps to then bridge and double power the front comps.
