[QUOTE="Casb0n, post: 8096234, member: 644750"] My 2 year warranty battery lasted 3 years and finally died. I went to the auto parts store to get a new one, and the guy there saw my subwoofer power cable and told me that it would be a lot better on the electrical system if I got a battery to put in the back. I told him that I only had a 350 watt rms subwoofer amp with a 30 amp fuse and he still said I should get another battery. Does this sound correct? 30 amps is barely more than the cigarette lighter fuse... By the way, my car has a 110 amp alternator I believe. [/QUOTE]
