[QUOTE="swrve31, post: 6346432, member: 614705"] hopefully someone here can direct me as to where im going wrong, and point me in the right direction. my equipment right now is a memphis 16-st1000d to a 15" rd alpha v2 in a 4.5 cubed box at 34hz. i just did the big 3 with knu 1/0. i went from alt to battery, then alt mount to frame, and then battery neg to frame. good clean surfaces on all. i noticed my gauge seemed to pick up like a volt afterwards. i put a 150 amp fuse between the alt and battery because i think my alt is either an 85 amp, or a 120. either way, i figured a 150 amp fuse should be sufficient? anyway, when the bass hits, i drop down to about 12 volts. it used to drop a lot lower before the big 3, but i thought this upgrade would help a little more? any ideas of where im going wrong? im hoping to downgrade to a smaller amp like a jl 500, and a good 10" soon, should that setup be fine? thanks for any input.
