[QUOTE="n2audio, post: 8371336, member: 540940"] This particular amp is basically a 2 ch (or dual mono). If your subs are connected at 2 ohms per channel you have 950w available per sub. So power is clearly not the problem. Also, at 1900w of available power and running the gain at a conservative setting the short term effects on your electrical system shouldn't be severe. I understand looking into alt/battery upgrades, especially if you're planning to push that amp to its limit sometime in the future. But I don't think your electrical system is the cause of your current problem. The +10, 0, -10 dial is not the gain. That's the cut/boost control for the bass EQ. The "input level" is the gain, and its range is 9v min to 0.2v max. If you have it set at about 12 o'clock that would be around 4.5v. Which would be on the low side if you have a typical 2v head unit. And with 950w on 600w subs you definitely want it to be on the low side. Definitely, and that would represent a problem with the wiring of the subs. Which was my suspicion from the start. All it takes is to switch a +/- connection anywhere between the amp, either sub, or either voice coil. [/QUOTE]
