[QUOTE="paulmarsh1222, post: 8490554, member: 669469"] Okay so it sounds like you're wiring both of those subs in parallel which is producing a one ohm load because each sub is already switched to 2 Ohm so then combining them like you are at the amp brings it down to 1 ohm. The amp can only handle 4 ohms bridged or 2 ohms per separate channel. That's why you're overheating so fast and so much. Also gain is not a percentage. You match the gain voltage to your headunit preout voltage so if your preouts are 2 volt your gain would be set to 2 volt. But that gets complicated with clipping and such so we won't go there. You need to use a dmm to calculate how much power the amp will put out. You should separate the wires and just take one positive and negative from one speaker and put it on channel 1 and the other 2 wires on channel 2. Each channel will be a 2 ohm load which will give you about 400 watts rms to each sub. Try all that and see how the amp performs and how hot it gets [/QUOTE]
