    Yea it ***** but I can only fit about 5.5 cubes in my trunk, using the 2 aero's I would have to have like 24" long port, if I only used 1 wouldn't be enough port area. It sounds good It just doesn't hit the low lows. I may design a new box after this one with a slot kerf port.

    Ya if u plan to run 4k to it you can make the box smaller. Im running my 12's in 2.2cu net each. @ 32hz Nice **** tho. Pictures dont do justice to how beefy those motors are.

    Big mutha humpa. High tune 36Hz is to cry. You cheat self out of whole octave.

    You guys and your crazy 4" coils.

    lol

    Only 3 inchers in that pic but she says that's a good size.

    I do actually have some 4" coils - my Dyanudio 30W100 and my Aura 1808. I've also got a 15" top for the Aura motor. SQ stuff though, you know me.

    But I don't have any sweet custom 5400 12's!

    Or an ULTRA, for that matter.

    lol No, that's Chris. I certainly have more than I need, but I'm slowly working on downsizing. I need the closet space back. It's hard to part with them for some reason.

    I'm sure that would sound just fine, hard to tell without an actual model of it. That doesn't tell me anything about FR or mechanical/thermal performance. Myself, if I owned that driver and I were to use it in a vehicle, I would go large sealed. Especially if I had 4K at my disposal. We all like different things though.

    Tune lower

    In for some new vids though when you fix your box issue, your going to have a NICE setup! I hope the rest of your equipment is as good
