Ok just to CLARIFY the reason i mentioned the DMM wasnt to see if the amp was clipping it was to say that there are fluctuations in the resistance at the amp terminals. maybe the amp was damaged when i got it. and i do not own nor do i know someone that has an o-scope. as for the subwoofer it self im not trying to go louder or beat harder. i like the p1's for their SQ and their price
