I have an Optima Redtop under the hood, and i have done the big 3 with 2 gauge. the problem is that i have serious voltage drops when it hits the low low bass notes. I redid my ground and its secure. I replaced my under hood fuse with a new one. I never had dimming or voltage drops EVER. Then i put in the redtop. I think the ground wire from the battery to the chassis has come loose. my neighbor was helping me pull my old battery out and he was kinda stupid. pulling on wires and sh!t. I should have NO DIMMING ON 750 watts with the big three and 0 gauge power wire. I never had dimming before even without the big 3, now all of a sudden i get voltage drops from 13.9 to 11v on the bass. COULD THE GROUND WIRE FROM BATTERY TO CHASSIS BE CAUSING THIS? I have replaced and checked every other f'in thing. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
