Review: 12” alpine sub - At first I thought this will not sound the best, after connecting it in the house for a couple weeks slowly breaking it in I put this in the car and my oh my this sounds brilliant, built strong and the bass punch and lows are great; don’t listen to others saying it’s no good, it’s not a competition sub but believe me will rock your car and flex your panels :)
