New alternator(<2 years but only 1500 miles TOPS)
New battery
Battery in trunk
0 guage wire from trunk to front for power
4 gauge ground from battery right to chassis in the trunk
Alternator has a ground wire to chassis
New power wires from fuse box to alternator
New alternator belt
JMF heatshield on manifold
Homemade heatshield on O2 housing
Im thinking that its either a bad alternator OR I need to run a ground from the trunk to the front. Anyone have any other ideas

My alternator wasn't new, but it was rebuilt in about 2 years. Starting the car, i'd have to step on the gas for a lil bit to have it go up in the high 13 to 14. After awhile of driving, it'd drop to the 11's - 12's. The dash lights would also go on about this time. Let the car sit for an hour or two and it "MIGHT" be ok. I went to LSE one day to pick somethin up and on my way home, the voltage went to the 8's, my lights went out, got home, turned it off. Car's dead.
I'm thinkin it could just be your alternator, but try the tips above.
After I replaced mine, it now runs like a champ. Except for the squeeky belt. been too lazy to fix that.
