[QUOTE="BnGRacing, post: 7606482, member: 557400"] Are you running your amp The other thing is 'RMS'. What the hell does that mean? Honestly, no one really knows as it's a pretty useless number. Average power over a given time is much more useful. With that, your 840w RMS amp may be producing an average power of 3-4x times that number. How? Easy, you jack the gains up. You're not making any more maximum power, eg; the voltage will only go so high, however it will stay at that voltage for a longer duration of time and **** up more current in doing so. So ya, lower your gains. If you've set your gains with minimal overlap with some equipment to meter clipping you may have something else kinda funky going on. Something as stupid as the chassis of the alternator having a bad ground can cause electrical systems to do some weird things. I'd just make sure you're using the factory ground location on the block. If you're trying to find the elusive Zero Ohm, well, your amplifier's efficiency goes right into the toilet at normal volumes. The amp will pull a lot more current, thus dropping voltage, and you'll get nowhere near the 80-90% efficiency ratings vendors brag about. That's physics for ya. So if you have a choice to rewire your woofers to 2 ohm instead of 1/2 - do it. Lastly, have you checked voltage going into the amplifier? [/QUOTE]
