I just got this installed last Monday, i believe the 13th, so anyway i have a 12bl fully loaded, sundown sae 1200d, should of got the 1500d, and all 0 gauge wire. I also have the box ported and built to specs. The only thing i need to do is carpet the box. I have all 0 gauge wire. My lights dim badley. I upgraded just the grpund wire in my hood with 0 guage and it stoped the dimming and could let me listen more. Just 1 problem.... How come when im listening to songs with really loud bass like beamer benz or bentley my system stops hitting for 3 seconds and then continues to hit, but if my volume is down it doesent stop.. Why is that? OHH by the way people think i have 4 subs in my car. Its very loud, i blow away everyone in my school lot easily lol.
