i plan on doing another build here shortly in a 90's something hatchback camaro....and he's wanting to run a 15" L7...he's already got 2 10" L7's sealed, but he wants to hit louder and lower.....so i think i'm gonna build his box at around 4.5cuft at 30hz....his amp is a kicker 1500.1 btw...does 30hz sound too low?

Go bigger on the volume (atleast 5ft^3)

Tune to 15hz and send him on his way....


No 30hz is not too low.

ill try to squeeze 5cuft in....but i've already did a 15" L7 in 4.4cubes at 34hz, and it turned out very nice...but it all depends on how much room i'm working with...so i think i'll stick with 30hz.

well as it turns out, the 15 won't fit....so were gonna build another box for his sealed 10's.....it's gonna be 3.1cubes at 30hz....maybe he'll like this better than his sealed

the 12's really like 2.5ish cf each. so i would go like 2cf each after displacements. like 5 total to 32 will slam.

5.0 cubes to 36 for two 10" L7s

i'll try to do some more measuring, but it dont look like i'm gonna get much more than 3 cubes out of his car....maybe i'll figure something out.
