i am going to be running a power acoustik setup and pulling somewhere around 150 amps i guess(1500 watts rms) and i am going to have a stock alt, stock battery up front but in the trunk i will have the stinger 1700 2db. neways would it be worth it to have a battery isolator for the stinger. they say they keep the voltage from dropping but i don't really understand how, i'm new to the SPL world and am trying to learn everything to make it work.
