i only have 7ft of 1/0 to use atm, should i go for my grounds first or pos?

if you can do it with 7 ft, i would do from alt to batt +, and from ground to chassis... and do the engine later

? We were talking about the big 3 not the amp's ground.

So I did a little testing and my voltage is fine when the car is running. At full tilt it doesn't budge from 13.8 (measured directly at the amp, it's prob a bit higher up at the alt). However, when the engine off it drops down into low 12's, but that's sort of expected.

I'll be picking up some 1/0 in the next week and some OFC knu 4g for my distro (currently using leftover raptor 4g //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif). If that doesn't solve anything then I'll prob just sell the AP and pickup a quart 1500 or somethin.
