[QUOTE="Komsan6063, post: 8088806, member: 641495"] Ok so basically one of my subs blew on my average *** system so i was thinking about replacing it. My options as of now are 2 Fi Bl 12s fully loaded in a sealed box or 1 Fi sp4 15 inch sub fully loaded in a ported box. here are the stats for both the subs. Basically im looking for something that will shake the **** out of my car. I typically listen to trap music, some dub step, and a bit of house. I want what is best for that shaking and the one that is most durable and will take the most beating. Thanks!
