Hey there all.. got a power question concerning my Steeda UD Pullies.. well I've got 3 amps for my sound system, (2) 500 Watt JL Audio AMPs for my 2 10" Subwoofers as well as (1) 125 Watt JL Audio AMP for my inside speakers (highs) ... well my question is.. will these two things need more battery power? I've seen some threads on this forum where power is somewhat of an issue regarding UD Pullies and want to make sure I'll be ok with the UD Pully MOD as well as all audio MODs I have right now without needing to purchase another battery or anything and I want to make sure it's not harmful to the car.. Thanks a lot guys.
