[QUOTE="Fi-brations, post: 7505402, member: 636442"] Im planning on upgrading my power in a while and i want to upgrade my electrical system to handle it. I currently have what's in my sig, and the sub amp is at 2ohms for 1300watts, my speaker amp is 50watts x 4, so 200, in my car, 00' bmw 528i, i have my battery in my trunk, stock it has 0 gauge or something like that running up to the front and to the alternator, i believe i have a 110amp, my stock battery is pretty large, the only spec i have of it is that it has 1000 crank power. On all this with 4 gauge power wire for my sub amp, I have dropped once to 11.3, usually if it drops below 12 it stays at 11.9 or 11.7.
