2nd Battery for Systems
As per Malice's Request Again: Here is how to hook up a 2nd battery in a car.
You will need a battery islolator, 0 gauge wire and a second battery.
You will need to hook up the alternator to the isolator, then the one positive to the starting battery and the second to the battery in the trunk.
Cost
isolator=60
0 gauge (18')=120.00
2nd Battery (Optima)=160.00
Terminals and miscellaneous parts=40
Total about $380
And that's it, very simple.

Well you will need a acid free battery, one that's gel filled for a system. It doesn't leak and doesn't rust/corrode like a normal acid battery. YOu also need that type of battery for a system, because it is deep cycle and has more amps than a regular battery.

well you can do it in series like that, i misspoke, good thing to have guys like you around 
But, we 240s like to carry the battery in the trunk for the reason of weight distribution, thats why I gave that option for the 240 owners. The srswap, needs the front battery to be slim or not there. So that's why I did it the isolator way.
But thanks for the advice
