ok the run down
1 dd 9515 dual 4 ohm
2 memphis st1000ds strapped together

fisrt run 140.1 not happy at all when i saw that then i remember that i hadnt check to see if my amps were still matched well they were way off
now here is the other thing that is weird my car has always liked around 46 to 50hz so thats what iwas using
2nd test run was better 143.4
so now i decide to do a couple sweeps
turns out with this bandpass my peak was quite higher
3rd run and final for the night

148.6 db in a 97 pontiac bonneville
front fireing sealed off from the trunk
ive still got som tweaking to do seal up the trunk alittle better take some more time at matching my amps output and figure out the fequency deal

so what do you think

thats not a bandpass at all
it looks more like a folded horn
if u was going for a 6th bandpass.(cuz the front of the sub was ported as well as behind the sub)
u should have made the ported area in front of the sub bigger

but all in all good score...i feel u can do higher but for what u did thats good
