well i know i wont for awhile but my future plan is to get a tahoe so i want to buy what would sound best in a tahoe, where i dont have to rebuy subs when i get it, but it will be awhile before then, do you think 2 L7s would slam in a tahoe, i know i would have more room to build a big box, what size box would be good for 2 L7 15s, and port tune? thanks
