the AutoTek 75.4 its rated at 100w @ 2ohm per channel and i have a full set of JBL speakers... front speakers are 100wrms no problem but the back are only rated for 60wrms. can i atleast get the amp down to 70w out of the rear channels?
Why bother? Unless you're playing test tones or clipping the crap out of the amp the rear speakers will be fine with that power and probably annoyingly loud. If you want less power going to them to tame their output, simply fade to the front.
