[QUOTE="KTMrida4life, post: 7583660, member: 637865"] Took an hour or two but I put in 3 new wires, all 0 gauge.. what took so long was soldering the ends. Ground -> car, ground -> engine block, and 12v from alt to batt. Really wanted to make sure its a secure connection so I had to find a massive soldering iron (couldnt find torch) to solder the ends.. but theyre sturdy. I had never looked real hard before, but the power wire from the alt to the rest of my car seriously looked like either 10, or 12 gauge. It wasnt 8. Tiny little wire.. I left it in place, and added the other wire on top. So.. now when driving, playing with the volume at 40/50 and my amp at roughly 1500-1600W, Ive only seen it drop down to 12.9V. Much better.. a whole 1.5V better because I accidentally made it hit 11.5V once before the upgrade. My interior lights dim just a bit, I'm not sure if my headlights do.. So as long as I dont ever hit 12.5V or below, am I safe? Im a nervous wreck right now because my amp power wire is hooked up without a fuse because I dont have a fuse holder. Im scared my car is going to be on fire when I look outside, and now its raining. Im going to unhook it tonight before I go to bed... [/QUOTE]
