One more extra bat ?

When you guys do systems with multi batteries, do you run the ground from the batteries in the trunk to the bat under the hood. Im doing this in my swift which is unibody and has poor ground locations in the back to start with. Any Insight here?double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

if you cannot get a good dround in the back then by all means go back to the batter in the front.    I have found typically in uni-body cars where you cannt get good ground to the sheet metal I go to the frame pieces in the rear of the car.     I dont know if that will work for you but worth a try2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

Agree, if you cannot find a good ground in the rear, run it up front. You can pretend your a SPL guy.....Top Secret, I can tell you but then my wife will kill me.

I use to could do spl. I just cant find enough space for 4 12's and still keep my cd changer, vcr, sat radio, md deck, DVD, 7 inch screen, 15 inch screen, N64 and Playstation2. So 3 12's had to go ;)double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

i definatly want to see pics of that :) I am sure you should be able to get a good enoug ground at the back, just ground it and then measure the resistance from the front battery ground terminal to the rear battery ground terminal.

here is one of the pics from the festiva....this was with the frame work done, the 2nd layer to the wall was not added or any reinforcements to the inside of the wall.   there are 2 seperate chambers each one was a bit shy of 10 cu ft for 4 subs with 190sq in of port if I remember right.2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR
