Options for getting my lexus louder...

[NJTStang11 10+ year member]

Car is a 1993 Lexus ES300.

Due to the fact that my gas tank is located behind my rear seat, I have thick leather seats, a padded rear deck, my seats dont fold down, and metal behind my seat, my car doesn't get nearly as loud as it should. After asking around pretty much my only hope would be to work out some kind of custom box to allow more air into the cabin.

All of these are involving removing the rear deck and the rear speakers from them.

#1-Bandpass it. Make it into a 4th order bandpass to allow more air.

#2-Port it. Design a box where the ports fire into the rear deck and reflect off the back glass.

#3-Change to 10's and design a box in which my subs fire directly into the cabin through the rear deck.

If it matters, subwoofers are Premier 3004's, amp is Hifonics 1606d.

I'm willing to alter the subs and box, dont want to change the amp though.

Out of those 3 options:

Which would be most cost efficient?

Which would get the loudest?

Which would mantain best SQ?

Which is easiest to do labor wise (I would do it all myself/with help) I can't afford to pay a shop for install work.

Thanks

#2 sounds cool.

All sound likely in an increase to get louder, although imo subs in the rear deck seems like an increase for theft, unless you limo tint your rear window or something.

I dont think he is putting subs in the rear deck just the port coming through there. But i could be wrong.
