so i just want to know how much bump you gain and how much quality you lose from using a bandpass compared to a ported.
thanks

You can get about a 6-10 dB gain with a PROPERLY DESIGNED AND BUILT bandpass.

This doesnt mean the ones at Best Buy!

They only play choice frequencies good. I would avoid...

it really depends on what order the box is and how it's built.
generally the more gain you get from a BP box, the higher it'll be tuned, so the more SQ you'll lose. Generally you'll see zero to six decibels of gain over a ported box, on average. The problem is that most 4th order boxes are tuned around 45-65Hz, and quite frankly that sounds like crap if you want any sort of deep bass.
bandpass, like ported boxes, roll off like a brick wall below the tuned frequency.

you have to be real careful with bandpass. i have built a few and they have involved a lot of calculation and were in instances where it made the most sense, mostly trucks where behind the seat space was non existent. in a car i would reccomend ported or sealed...

what kind of car?
you could go ported or snailshell depending on the space available and skill level of the builder.
