hey, i plan on putting 2 10's in my car, my car is slow enough, i heard that subs can slow down your car quite a bit, and lifting up my bros 12's i can understand that, do you guys think that subs will actually slow your car down?

 

In most cases, the box weighs more then the actual subs. If your that worried about it, then get yourself a box made out of fiberglass. Or atleast make it easy to remove. Then you could take the subs out for draggin on the strip.
