WOLFRAM FTW
90 amps is low man mine is 125.. u can try it maybe upgrade battery to a agm under hood if u haven't and get big 3 wires under hood.. see how it does with either new agm or big 3 set gain low still be more power than u had even not using full power of amp.. biggest problem maybe headlight dimming..90 I believe. I have 0/1 power and ground wire for the amp. Just a get by car until tax time. My box is a huge slot ported box. 4.25ish cubic foot.
