my crappy carpet job

i began to make this sealed box to maximize space in my trunk which it did, but when i got done i realized that i could have made it a little bit smaller. What do you guys think about 12" LI's in 1.75 cubes each sealed (recommended 1-1.75) ??? thats not to big is it ?? i was going to try it out when i get my subs in and maybe mess around with a smaller box later if i dont like it, but i hope it will be fine.

you can always throw some extra wood on the inside to lower the volume.(ttt for a helpful topic)

wheres the port? a little small for a ported box for 3 W3s. i think that's even under what JL recommends sealed. looks good though.

 

[soundstreamer 10+ year member]

it is too small. according to the owners manual the dual2-ohm should have 1cuft and 13" of port each. i disigned the box for two of the subs cuz of space restrictions...poly-filled...stuck in a third.

the port comes straight out the side opposite the speakers. i didn't want to deal with the ending the port on a sloped face.

I'm finally building my first ported box and it's gonna be a big'un.

5.499^3 including port. I just want someone to check my design before I start cutting.
