Okay so i have 2-12 kicker L7s installed recently with a 1300 watt phoenix gold amp , i know there underpowered . My issue is my windows rollup slow , my lights dim while mybass hits and my battery has died on me 4 times , could there be a drain ? Or my batterys life span is about done , im trrying to upgrade to a single battery that will push my system and be good for daily use. Im running everything with a 4 gauge , and my alternator was replaced about 2 months ago so i know it cant be that.i heard optima yellowtops would be good .
