[QUOTE="Tripn88, post: 8440351, member: 666968"] Also I don't think that 80hz +2 is the slope. That's your EQ. Guess you have 80, 100, 120, 1k, 5k or something along those lines? Maybe your lpf and subsonic aren't set right on the amp. That's why your not getting much out of it. On my amp both current 15.1 and memphis 500 my gain was less than half. Closer to 25%. You need to match the voltage from headunit. If you look all the way to the left is maybe 9v all the way to the right is .5v. Your could be different. But if you set it at 9v that means it would take 9 volts from your headunit to have the amp put out full power. If you set it at .5 that means it would only take .5 to play at full power. Now when you put it at .5 and your headunit is at volume 3 and your subs at full tilt when you turn your headunit up past that your clipping and that's causing the excessive heat.... [/QUOTE]
