Need to move more air in trunk car..

[86yota 10+ year member]

Got 6 12" CVRs off a Sundown 1500d at .5 ohm with decent voltage and only pullin a 142.8 in the trunk of my Grand Marquis. Now I know these cars and similar trunks KILL your score, but what can I do to help this? I have 3 subs firing back, 3 firing up, and port firing up. Should I try to build a box with external aeros firing straight into the car? Any crazy ideas? Im almost ready to try 4 15"s sealed but would like to improve with what I have.. thanks

maybe you have some cancellation with all those subs....try building a good box for 2,3 or 4 of them....

or you could sell it all and get 2 12" to fire sub and port forward:idea:

do u have a "ski" port that opens up into ur back seat?.....try and open up some way into the cabin of the car if your answer is no

I'm in the same boat lol literally. I keep going through setups and i still can't seem to get to where i want it. Granted I stuck with a single sub setup I went from a w7, to a 18" bl and now im waiting to get my btl to put back there. Only suggestion i could make is take out your rear speakers. I'm thinking about doing it but there a ***** to get to.

Guess I shoulda gave more info. Metal wall from trunk to cabin is cut out mostly, no more 6x9s, arm rest is cut out for the "ski port". Deadening was also removed from behind the seat. Just need a box to push more air into the car..

doesnt sound like enough power for 6 12's

Eh..either its my box or my Sundown is killing them because they can get stinky after full tilt for a couple minutes. I have a 9 cube box with 140 sq" of port area (port looks huge) and I dnno if that effects their power handling or not.. They should be roughly getting only around 300 RMS a peice tho..
