[QUOTE="Heeltoeclutch, post: 7293498, member: 629974"] Thanks for all the help guys. I just went out to my car and I can't set it to 3/4 full volume because my speakers start to puke at a little over half, even with 125 Hz HPF (stock front speakers rated at 40W, running 102ish watts to each). I never listen past like 14 out of 40 though; 15 will make your hearing fuzzy for a while [IMG]//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif[/IMG] They sound awesome at the volume I listen at. So I put it at 20 and took measurements; with gain at 1/3ish voltage was 2.67 out of the bridged terminals. I tried measuring amps across the power terminals and then realized you have to measure with the meter in series [IMG]//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif[/IMG] I tried hooking up the E8 to get an idea of the output and it's no use, I do need to change my setup.
