I would like to move my battery to the trunk of my car. Currently, I have an amp mounted to the back of my rear seats, and a small JL Audio 8" subwoofer box. The Amp gets it's power from a 5 guage Monster Cable that is run from the postive battery terminal all the way back to the trunk. What I have been wondering is, could I just move the battery to the trunk and cut the Monster cable a install the battery in line into the circuit and have the Monster cable carry the power back up to the postive battery terminal in the front of the car? Here is a very *simple* diagram of my current set up. (the dotted line is the Monster cable and the vertical lines are the seperation between the trunk and passenger compartment and firewall and engine compartment.) Battery/Pos Battery Cable/Monster Cable>-----|-----------------|---<Amp And this is what I am wondering will work or not?

Just a quick question...why do you want to move the battery? Typically this was done in rear wheel drive vehicles to move a bit more weight over the rear (read drive) wheels. With an AWD vehicle I was just wondering what the goal was?
i think it would help removing some of the weight from the front causing less understeer.. however, i`d be careful cuz i would think that subaru probably weighed the car on the left/right scale, trying to achieve maximum balance to really take advantage of the sym awd layout. this is the same reason why one should make close observations messing around with aerodynamics.
I have 0 guage Monster Cable for the negative & postive in my truck. Its been that way for about 6 years and I've never had a problem.
Good to know it will work. As far as moving the battery. I would like to get some of the weight off of the front wheels and free up some space in the engine bay. I am going to be locating the battery in front of the rear axle on the passenger side of the car, the other option I have been looking at is getting an Odyssey 680 and mounting it under the passenger seat. As far as Subarus symetry and weight balance, there is a lot more junk on the right side of the engine than the left. You have the battery and water tank both hangin out on the driverside of the engine...now I am not even pretending to know about what subaru based it's decsions on when it set up the weight balance of the car, but logic tells me that if I can move some of the weight lower and to the center of the vehicle (between the axles) then it will help out...and I am not scared to just try it and see. If it proves wrong, then I can change it back.
yeah, pretty sure arguing the designed location of a 40lb battery in relation to the left and right weight balance is a moot point, how the heck is Subaru gonna know if a 400lb sumo or a 70lb midget will be driving the car.
if you want to get weight off the front the car i would just get a small battery. buschur racing used to sell a kit that looked tempting...just throwing out some options here.
I agree, I am actually much more interested in a light weight battery. I also trying to get the crap out of my engine bay. The Odyssey 680 is what I have been looking at...it will fit underneath the passenger seat.
Cool, just curious what the objective of moving it was. I had a buddy that did it to get it closer to his amps for better output, lol. But he also put one in the front as well as the back and ran them together from the alternator.
Yeah...no...I set my stereo up to be just good enough to not have to worry about ever again. I have 1 500watt 5-way eclipse amp that powers everything.
Why move it to the back? Is if to space in the front? You add so much weight with all the wiring. Just run a smaller battery in the front. http://www.braillebatteries.com/ I've been using them for 3 years no problem. Even with 20w50 in the engine its got plenty of power to start the car in 20 degree weather.
the gas is more explosive than poisonous. Hydrogen to be precise (rembember the Hindenburg disaster). You do get some S02 gas, but what really causes it: electrolysis during charging. If you wish to keep a factory sized battery they make sealed containers for those batterys which you can vent to the outside of the car. this an old drag racer trick. We always put them on the driver side b/c the physiscs of RWD cars puts a lot of pressure on the right rear tire during launch if the suspension is set up correctly. I spend years with open batteries in the truck of my and my friends cars... maybe thats whats wrong with me. hnoes: Of course, the sealed batterys dont even leak when they're dirty side up! :bowdown:
Moving weight between the axles will reduce the polar moment of the car and moving weight down will lower the center of gravity. The down side is the additional weight of the wires. Perhaps a small sealed battery under the passenger's seat will be best for overall performance. Shorter wires combined with the lighter weight battery will add more performance wise than a full size battery in the trunk.
