hey guys. i know this sounds crazy but i need to find a lightweight combo for my car. its not an all out drag car, still has wheels and interior, but its a fast every once in a while car and the 9sq ft box and 3 xxx's is waaay too heavy. i know that anything decent isnt going to be exactly lightweight, but i need a sub that doesnt way 75lbs. i want the best i can get without adding too much more weight to the car. no budget limit. im thinking its going to be a single sub setup. help me brainstorm guys. i know people here have dealt with many different subs so im trying to see if there is something you guys know of that performed really well but didnt weigh too much.
