I have a dodge charger im trying to put some sundown subs in and I need help picking a line. My goal is to be very loud on music and 30-35 tune. I currently I have a DC alt 270xp, 4 xs 3400's batteries, and im either going to order a DC 5k or preferrably saz 4500 (if i can find one). also due to trunk space....I can't have 15's ported. so it's either 2 12's ported or 3 12's ported. What line of sub and how many is my best option?
