[QUOTE="Andrew hcca, post: 8716720, member: 680768"] So this weekend I dug into things and my gain was set way to high, when I initially lowered it I did it without a meter and kicked it back up a little didn’t realize I set it even higher than before. But even max power from my amp without distortion I’m still burning shit up. I’m waiting on a new re cone kit to come in since the last one I was sent had some scuffs and traces of blue thread lock in the spider mounts that set me back a little. My brother has been helping me with the tuning, he says my gain should be set to 74v based on his equation he uses which I’ll list at the bottom. But to me it just doesn’t seem right considering 74v is barely pushing these things.. I’m running duel 300a alternators with duel batteries. I do NOT have the batteries isolated. I have a yellow top up front and a 31 group in the back run in parallel. I have 2 runs of zero gauge connecting them. And multiple grounds to the rear battery including 2 to the frame, and one to the body in the back. And upgraded 0g grounds at the front too with the big 3 upgrade. I only have a .2 voltage drop in the rear. This is his math he uses Set gain with DMM- V= SQUARE ROOT OF PXR (P)= amp rms (R)=Resistance of speaker load EX. my amp 300x4=1200 300w per bridged channel 4ohms each sub on their own bridged channels square root of 1200 =36.4 V=36.4 Play 50Hz test track with speakers disconnected while adjusting gain [/QUOTE]
