do i need another battery

Recommended Posts

i have two P1 12's being powered by an Alpine MRX-M50 (500 watt) and my lights already dim when the subs hit, even when im driving. i was thinking of changing to two 10's maybe p3's or W3v3's and a JL jx1000/1. My question is whether i would need another battery to power that amp with or if maybe my alternator or battery might need to be replaced.

haha on the beetle quote, but you probalbly just have a loose connection some where. id start by checking the ground wire. i mean your not running a big system...

check your grounds, alternator and your current battery (load test) autozone or any store like that will do something like that for free. do the big 3 as well. and its always a good rule of thumb to beef up your electrical... even tho ur running low watts i would still add an extra battery... just good practice.
