dkahns51 Posted April 16, 2011 Report Share Posted April 16, 2011 Should the 2nd battery in the back be as close to Amp/AH as the front battery or does it matter? I have a optima yellow top up front and i wanted to run a XS D1200 in the back. (I will have around 3000 watts) Or should i get a bigger battery in the back like a D2400 or D3100? or 2 D1200? Shit yeah im confused **Clicky>>My 2009 Subaru Impreza Outback Sport Buildlog<<Clicky** I'm messing up 98% of the time Link to comment Share on other sites More sharing options...
speedball1978 Posted April 16, 2011 Report Share Posted April 16, 2011 go with a d3400, and get 2 if you can.. but as far as amp/h thats not relative to what you have up front, it don't have to match Link to comment Share on other sites More sharing options...

dkahns51 Posted April 16, 2011 Author Report Share Posted April 16, 2011 Buy the biggest one that fits your budget. Alright so If i rock 2 3400's in the back i don't have to get a isolator or anything? just straight 0 awg to the back? If i got 2.. would i have to run 2 positive and 2 negative 0 awg to the back? 1 for each battery? Or should i just run 1 set and wire and then just wire the batteries in the back together? **Clicky>>My 2009 Subaru Impreza Outback Sport Buildlog<<Clicky** I'm messing up 98% of the time Link to comment Share on other sites More sharing options...
speedball1978 Posted April 16, 2011 Report Share Posted April 16, 2011 don't use an isolator, that puts more resistance on your charging system, if you get 2, 1 run of positve and negative will do just fine.. you're only running 3000 watts which in turn is going to be roughly 300 amps... a single 1/0 run can do 300 amps.. but again multiple runs are fine regardless. Just make sure you fuse each wire 300 amps at the front battery and the rear batteries Link to comment Share on other sites More sharing options...

Do you also have to fuse in between the 2 back batteries? **Clicky>>My 2009 Subaru Impreza Outback Sport Buildlog<<Clicky** I'm messing up 98% of the time Link to comment Share on other sites More sharing options...
speedball1978 Posted April 16, 2011 Report Share Posted April 16, 2011 i did, but you don't entirely have to.. some people have fused 12 inches from the front battery and then fused the amp.. but its your choice in reality Link to comment Share on other sites More sharing options...
