1mtx1 Posted September 1, 2009 Report Share Posted September 1, 2009 Im having a issue where my sundown 1200d is only running off my back batt and my bass turns off at higher volums(21 out of 40). my back batt is a kinetic 1200 and i have a stock front batt. i ran a power wire (4ga) to a fuse holder and from the fuse holder i went to the batt + to the amp+.Then grounded the batt in the back i used a diff screw then the amp ground but it's pretty much in the same area. All wire is knu 4ga and i have it all fused with 150 amp fuses.At first my back batt was charging up and was at 14.4 now its at 12.4 and my front is at 14.4. I did my grunds under my hood with 1/0 ga and i know with the back battery working i was not geting any volt issues. so what is cuzing my back batt to not charge? oh yea im wired at 1 ohm and my rca's are fine and the sub,amp,batt are less then a month old Quote Link to comment Share on other sites More sharing options...
troy Posted September 1, 2009 Report Share Posted September 1, 2009 try to put your ground in a better spot. sand down a spot put a terminal on it and bot it to the chassis somewhere. if you have the wire run the ground back to the alt and ground it on the case. see if that fixes it up for you.

troy Posted September 1, 2009 Report Share Posted September 1, 2009 also try and power tha amp with the origianl power wire. thatll eliminate the battery being the problem also if the ground doesnt fix it.

1mtx1 Posted September 1, 2009 Author Report Share Posted September 1, 2009 also try and power tha amp with the origianl power wire. thatll eliminate the battery being the problem also if the ground doesnt fix it. if i try the new grounds and it still happens to do the same thing ill put the power wire to my amp and go from there. i have a spot where the stock subs was it right near the back batt i could do my ground there its would need to b sanded and i could use a 1 foot ground wire in that area . thanks bro Quote Link to comment Share on other sites More sharing options...
TheSundownFire Posted September 2, 2009 Report Share Posted September 2, 2009 (edited) You running your stock alt? If you are your alt may not be keeping up with charging both batteries especially with the draw of the system on the rear one.
