Alright i plan on running 0awg wire. from the battery in my engine compartment all the way back to my trunk. the battery will be a kinetik 2400 series. First Q. What size of fuse should i put between the batteries? Q. I would then run wire from the trunk battery to a d-block? the main question is.. Where to place fuses at. ------------- SSounds

ALL power cables should ALWAYS be fused for its capacity (#4 - 150A, #2 - 200A, 1/0 - 300A) within 18 inches of ANY battery. And, YES this means both ends!

I suggest at least a 150 amp circuit breaker at each end of the interconnect cable. With 1/0 AWg cable you can go up to a 300-350 amp breaker. And don't forget to properly vent the trunk battery... and be sure your alternator has enough capacity to charge them both. ------------- Support the12volt.com

well hmm.. i will have 2 crossfire vr-1000d's and a alpine mrv-f345 4 channel. what do you say i do? Upgrade Alt. what size of alt? will a 200amp idle alt. kill a battery? or is it, it can produce 200amp if needed at a idle? upgrade the battery in the engine compartment? add a second battery in trunk? ------------- SSounds

I'd get a one wire 250amp alt and run your 1/0 wire from it back to your trunk batt. Put a 300 amp breaker on each end.10 to 15 inches from the alt and batt, then run to your dist block from your batt. This way you will have 2 alts 1 to run your car off of ( lights, a/c, seats, window.....etc. And 1 to just power your system.  ------------- Big Dave

Zena does HO single wire alts and multiple alt setups for any vehicle. I've used them and they are very reliable. ------------- Support the12volt.com

Many folks out there run dual alts with no problems. I have had more trouble out of the stock oem. 03Impalla my upgrade does very well. of course if you feel like you can't do the upgrade your self take to your local shop. They will fix you up. And as always any advice is what I would do, your results my very. ------------- Big Dave

thats is a very interesting site but everything is 600 bucks for half of that u can upgrade with a single ho alt and not have any problem.. that is what i was getting at it.. i know that people use dual alts.. but i haven't seen any on the street, mostly in comp cars only ------------- S.O.B custsoms..
