How much space for 2 L7 15's?

My friend wants something loud. It's going into an SUV. I'm just wondering what kind of airspace is needed and tune to what? Anyone used these subs before?

A 10 gallon trash can should be sufficient.

Tune in the lower to mid 30's for music.

Depending on the power you're running, 8-10ft^3 common chamber with a 33-35hz tuning and about 110-130in^2 of port.

Thanks RAM. I was looking up specs and somehow came up with 10cu/ft tuned to 34hz. Going to be running off 2500rms, but i give it a true 1500rms.

Oh and 120"^2 for port! Hoping this will be better than the prefab 4.5cu/ft(including ports) ported enclosure that they are in //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

it's a hifonics, not sure what model, but claims 2500rms @1. With a 4 gauge input for power wire... I give it 1500rms, maybe.

I'd go for even more if you had the room. 6 cubes each is what they recommend. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I'm building for a single 15" L7 right now and I'm using 5.2 net just because of space constraints.
