RE SX12 in 93 Caprice Classic

I'm looking for some advice on building a box for this thing that fits snug all the way into the back of my trunk. I have a single old school RE SX 12" and a hifonics 1605d amp pushing 1100 watts to it at 2ohms in a 93 caprice classic. I'm looking for a SQL setup that hits deep.

RE offers what they reccomend for SQL boxes, as well as SQ and SPL boxes, for their drivers on their website.

Lol "SQL"

There is SQ and SPL,   NO SQL this is something made up to sound cool. SQ Sound quality   SPL Sound Pressure Level    SQL  ?????

SQL is both. There is such a thing. I've heard it used many times.

Lol...its for people who want to be cool...JL Audio actually once called their W7 line of woofers "SQL" woofers haha Also one note...if there is such a thing as "SQL"...why aren't there any "SQL" competitions??? If "sq" stands for "sound quality" and "spl" stands for "sound pressure level"...what does "sql" stand for?? "sound quality level", "super queer level", "sonic quantum levity"???

I hear it used more and more these days

SQL is Structured Query Language...but that's not car audio :)

Well I am afraid just because people say doesn't justify it as actually having meaning, people say many things. If they eat poop, will you?
