[QUOTE="rlambert02, post: 7984128, member: 634108"] Ok so here's what i already have: Mechman 220 HO alt Big 3 wiring optima yellow top (front) XSd3100 (rear) AT OFC 0g throughout Full copper terminals soldered Problem: At idle my car sits at 13.8 (dont most cars idle at 14.4?) but when I put my saz-3500 in a week ago it cut out after 3 seconds of play, thought i blew the fuse, then today when i was redoing my build i noticed the fuse was fine so decided to some testing. Hooked up the 3500 again tuned with a dd-1, at it was dropping down to 11.2 at just a little over half volume. With what I already have shouldn't i be able to hold at least 12v just fine. Tomorrow im going to do 2 runs of 0g from the front to the rear, but do i go from the front batt to back batt or the alt directly to rear batt. What should i try to do, get rid of the yellow top and upgrade the front battery? I'm really trying to not add a second rear batt cuz im having a lot issues with rear weight and ride height. Any help or advice is appreciated. Thanks guys. [/QUOTE]
