View Full Version : bandpass through rear deck

02-02-2013, 09:55 PM
I am going to be redoing my box here before too long and thought about going with a bandpass ported through the rear deck. I had a factory 10" in the rear deck so there is a nice open space anyways. I have a pair of RE s-e-x 10"s getting about 800~ watts rms each.

I haven't seen any bandpass/trunk builds so I was wondering if anyone has experience here? I would probably end up with really close to 2:1 ported/sealed and I have a 6" aero I'd be bringing up through the rear deck.

I've never designed a bandpass but my buddy has done a ton and has quite a few trophies ans titles under his belt but he always does walls and suv's. I was thinking like .6~ sealed each and like 2-2.5 ported.

Does that 1.25/2-2.5 sound good? I hear a lot of people say 1:2 sealed/ported but...
