sun of a b****! I need your help guys. I had some electrical issues tonight on the way home. the car started up fine. I let it idle for about 5 minutes before I left work. Came to a stop and put my left turn signal to turn out. When I hit the brakes and the turn signal at once the headlights flickered. My 3 center guages on the dash board flickered on and off. The radio cut out. the a/c cut off. It was as if I diconnected the battery for a split second. Car was still running. The passeneger windows would not work. Which what happens when you disconnect the battery. What the hell!?!?!? The car drove perfect for an hour this morning. It drove perfect on dinner break tonight. It must be all the lighting that was on!? This scared me because I wasnt sure if I could drive the car home or not. So I turned back into work and parked. All my connections were perfect. Nothing came loose or undone. I cut the car on and off a couple times. No issues. But at idle when I revved the car the headlights flickered and the center gauges flickered on and off.
So then I turned the car off once again and it went completely dead. Even the rpm needle stopped at 1200 and didnt go back down to 0 when I cut iff off. I tried to turn it over again twice and nothing! I let it sit there for a minute and it cranked up like a charm. When I revved it or hit the brakes the lights didnt flicker. It was like it used to be. So I let it idle for about 10 minutes. Then left to go home. It did good for about 5 miles then te headlights started pulsating bright to dim just cruising. Not any electrical draws. I even turned my ac off, radio off, and fog lights off to save as much power as I could. I made it home in one piece. This must have been meant to happened. I made a pit stop at a church parking lot on the way and as I slowed down to turn left into the lot, 3 large deer came darting out of the trees from the right side of the road. Holy s*** I came so close to being nailed. Which I would have if I didnt turn.... scary huh?I also had to drive it slow. As soon as I gave it good throttle the engine was cutting out.....
Anyways. What the hell is going on. All conections are perfect. I have a feeling it could be a grounding issue. Could this be? I have 3 4 gauge wires in the back being grounded to the floors sheet metal. All of which I used a grinder on to contact bare metal. Any advise would be appreciated. I hope to get up and try to fix this in the morning.
I need to run it for longer than a day to let everyone know.
But so far so good. Its running great! 9 minutes away from getting in it and going home.

Haha, finally got her done huh bro. Good s*** bro. Since u disconnected the battery I would give the car a day or two of normal driving just so it can get a lil better learning of what's going on. Your fuel trims may wind up being. Closer to zero than they are now. Or of course further. But yea I'm happy you are loving the new setup bro. Enjoy it.
Also, what size(gauge) cable are you running from the trunk for the battery? Id recomend running 0/1 gauge if you aren't already. It make help that weaker cranking siince it will have less voltage drop with the bigger cable.
Also, I recommend running a ground (4ga is fine) from the battery straight back to the front as well. The 6 sometimes has ground troubles if its only grounding in the rear from the battery.
Keep me posted on how u feel about the new setup. Again, glad u like it so far. Win win bro.

Thanks for the responses.
I have the car in the garage now. I removed my sub box and the carpet in the trunk. All the connections are good. There is one ground wire in the trunk that is a little loose but nothing a larger screw wont take care of. As far as bad battery. I dont think so. Its starts up as soon as it turns over. Earlier today I had the car running with my 15" sub blasting and no issues. The system sounds louder now...
One thing i noticed is that even with the radio off all the way home tonight. The amp in the trunk powering the sub was quite warm. the laser temp gun I have said 100 degrees.
One other thing is I dont know if the exhaust itslef will make the floor in the trunk rather hot?? When I took out the carpet the floor was pretty hot at about 100 degrees as well. I took the laser temp gauge to all the wiring and nothing was hot. They were all pretty cool.
so its safe to say grounding issue? Is the trunks sheet metal a good ground or should I go for something in the trunk that is more solid?
As far as it being too much on the batter. Yes and no. Before there was no issue with lights diming with all my lights on and the system blasting. My headlights have never onced dimmed since I have had the car. Then i say yes because when I hit the brakes and use the turn signals it draws down the voltage big time.
I forgot to mention that using the voltage meter ont he dashhawk. during idle and cuise its 13.5 volts. When I hit the brakes and the lights dim and flicker. It drops straight down to the 9's and then comes back up.
sun of a b****! I need your help guys....
It sounds like your alternator is going bad. I only say this because of the voltage changes that you reported.
I got to leave the house in 3.5 hours. Let me see what I can do. I dont have any 4 gauge wire to run to the front. Let me see if I can make some better grounds in the rear.
and if you used 4-8ga for your power run from the battery back to the front. thanks definately going to need to be bigger. like the 0/1ga when u get a chance.
