I put my battery in the trunk via 2 gauge wire. then I hooked up the 2 gauge main power wire to a 140 amp circuit breaker and then I hooked up the other end of the breaker to another piece of 2 gauge wire which in turn is connected to all of the wires that were connected to the positive terminal when the battery was in its original location. the battery is in the trunk in a alum box which is vented. the battery is an optima red-top. the ground for the battery is 2 4 gauge wires each indepently grounded to the chassis of the car in the spare tire well. I wire-wheeled the paint off before I connected the grounds. My question is: is 140amp breaker too much? I'm thinking maybe I need a 100 amp? I dont care about nhra rules or anything so thats why I did not install an external cut-off switch.

and 2nd, do my connections sound sufficient?I tihnk i'll have to ground the engine with a ground kit once I get everything done. thanks in advance for any help.

considerring the stock alternator supplies 75 amps, your 140 might be a lil' too much. the 100, i think, would be a much more prudent choice. so whatcha gonna do with all that room up front now?

i know on my 4gauge wire (which is really way to small) i blow 60 amp fuses left and right so i soldiered the 2 pieces of 4 ga together. i'd keep the 140 the only reason i tried to fuse it was incase th epower wire shorted against the chassis. and 140 would blow if that happened....

I've been using a 2gauge power wire with a 100 amp circuit breaker in the trunk for almost three years now with no problems. Also I used one 2gauge ground wire bolted to one of the shock mounts on the rear shock tower (with paint wire wheeled off) and no engine grounding kit (other than the factory ground leads) with zero problems.

I am planning on sending my battert to the trunk too. So what would be the best combo wire and breaker to go with?

And are these the same breakers lots of stereo guys use for amps ect?
