Right now i have 2 10" Apline type-R subs in a Q-Logic Hatchback Sealed box and I want them to hit harder....Since i want them hitting harder I was going to get a Bandpass for the subs....Does the Fit of the bandpass to the subs make a big difference?? How much harder will these subs hit in a bandpass over a sealed box???
