Was wondering if its worth replacing the stock sub with a kicker rmb8 if I have a bandpass box with 2 12" JL 12w3's, or would it be better to remove the stock sub to let the air pass through? Would I even hear any added difference from changing the stock sub or would the 12's drown it out anyways?

 

I removed the stock sub and just left it open. The only thing is there is a little bit of glare at night from the brake light. no big deal.
