The shop with the bandpass idea is trying to get you more output. Here lies the problem though that the other shop mentioned. If you use a bandpass you cannot see or hear the subs movement. If you go past the subs limits or under the tuning frequeny you wont know till you cause damage. You can set the gains properly and set a subsonic filter to help avoid this, but if you start using alot of extra bass like from a bass controller or even from the deck you can still cause damage. Now for the positives about bandpass. It will get louder than a ported box ( in the range that is efficient), and in this case becuase they want to port into the car vis the rear deck it wil drastically reduce that rattling trunk sound. I personally prefer the ported box and some sort of sound dampening(dynamat) on the trunk lid. Hope this helps.

i had a 90 caprice, took out the back speakers and ripped out that 1" thick rubber deadening behind the rear seat and it was pretty much like a hatch back
