hey guys have a problem here im new to all this high end car audio stuff never really had anything past 1000 rms. tell now and my problem is i own a 2001 kia sportage that had a stock 70 amp alternator in it so i went online did some research. and found a shop online that built me a 180 amp ho alternator for my car since i already knew i was gonna need one for the setup i was gonna go with.well after getting it in and installing it i did a big 3 upgrade with 4 gauge wire since i was told with the setup i got 4 gauge should be fine.so after doing the big 3 upgrade i upgrade my stock battery to a optima redtop battery and run 0 gauge from the battery to my amp which is a cadence z7000 thats running off 2 12inch kicker L5's. but now im running into problems my voltage drops down to 13v-12v's sometimes 11v when driving and it drops down to 12-11v's when at stop. and was wondering if i did a big 3 upgrade to 0 gauge u think it would fix my problem or would i need to get a battery as well for the back if so here what i found let me know what u think sorry for all the words lol.
