My USA 2000

[Mynameismcgyver 6]

Have 4 fresh Usa 2000's that have never seen power. Going to run one one my FI Bl 15 in my 2001 Nissan Maxima with aftermarket battery and stock alt. I wont be killing this setup but will it not kill my system until I get an 130Amp alt for it...And possibly a second battery if I need to??? Again, I wont be pushing it way too hard but ive heard these amps draw alot of current.

do it jes behave untill u get the 130 amp
