Ok im scraping the plan for my single 18 build. And going with a 2 15 setup. Going for a daily setup
that will produce good db numbers on TL for the org i compete in.

Heres what ive came up with:
2 Audiopipe Txx-BF15s
1 DB Drive Pd2000.1 wired to 1 ohm
im going aero port(s) Externally (2 6s or 1 8)
tune 40hz - 42hz

L36
W24
H18
9 cubes gross
est. displacemet for subs is 1 cube
so 8cubes after displacement

im tuned in the 40s for daily and its not the best for that deep ground pounding stuff. i would put you somewhere in the range of 35 but :imo: so with your aero you can try everything ;)

the12volt and torres are wat i use on the fly for testing to get a good estimate.

Daily while producing a "good number" is very hard to achieve. The best idea would be to plug a port or two and alter tuning for daily then unplug them for SPL runs.

^^^^^THIS... or make a plate with different aeros on them so all you have to do is chance a few screws.

Your still on a budget build lol...

It will be a trial error setup as we have told you before. Anything with SPL as any type of a goal will not be done in one try.

Enclosure size has many factors and your end goal.

I have not modeled those subs before but I would start big and a decent amount of port area. Then adjust tuning to try and find that happy medium area.

After that it is just a matter of rebuilding several times to see what works best for what you want.

would 1 8" be better then 2 6s? as far as the port area goes
