Cone area and power typically net a lower increase in results then a few 100 or so hours of testing.

My XL 15 was louder on less power but that was not tl. I wouldn't mind going back to another 15 but 3.5 cubes swallows my trunk.

typically didn't measure twice before they cut...

Some times when chasing numbers what sounds good to ear will not work best on the meter. Same goes for any kind of mathematical figures we do. There is no way what so ever that we can design an enclosure (wall or other wise) and promise a particular SPL number. I don't care what any designer or builder suggest...it is in no way possible.

How much have you guys gained by just adding deadener? Which be a bigger gain going to a 15" or adding the deadener. Common answer is both but only able to do one at a time right now.

If you are serious about trying to get louder. Owning a meter is far more beneficial than adding anymore equipment.

this.

start by making the trunk seal off 100% air tight, there are 2 vents in the trunk that vent under the bumper cover, make sure to seal those up real good

Sealing off the trunk wont always gain.
Id try a single 15 if you have the space.

sealing off the trunk is the most time consuming experiment for your car. subs all the way back with a long port/s at the cabin entry always works

There's nothing better then a sht load of time put into an enclosure that doesn't work

About 145 sealed on the dash in the civic with my 18.
I should have my sub fixed in the next few days and switches out the 2 6" aeros for an 8". Should be able to meter again soon.
