Help with box for two 12s.

[SquishY 10+ year member]

Anyone mind helping design a crx style box for my not crx? Got 38.5" wide x 24" deep x 14" tall to go in a '00 Tiburon. Aiming for two undecided 12s and a new AQ 3500. Electrical is going to be upgraded as well, no worries.

Didn't think of that, sorry. Its been going on two years since I had anything to do with this. I've been eyeballing some Sundown Nightshades for the 12s. But if you think some 15s could fit in there I'll go with AQ HDC 15s in that case.

Guess it should also be mentioned that I do want a tune in the low 30s.

I'll look him up. I'd do two 15s if I can fit em without messing with the back seat. One 18 might could work though, can a nightshade take 4k daily and could I expect good numbers with a low 30s tune? This is the first time I'm even really considering competing but it must be a good daily ground pounder at the same time.

I recommend the single 18. It will allow for more room for the enclosure to occupy. This will be likely more efficient than dual 15s in that space if designed right.

Sounds good, one 18 could most certainly be fun.

To get my full 24" deep would it be of best interest to do the ports on the sides of the box where the hatch area widens out instead of taking a couple inches off the box or choking the ports on the car? I built a box in a friends Eclipse like that a while back and it sounded and performed well for the little planning that went into it.

That makes sense only if you were worried about mounting issues mainly. Compression is compression regardless of where the ports are located. But, yes, for a sense of stability in the physical part of the design, by all means. Now, when the port is calculated, it may need to wrap to the rear of the enclosure as well, so if this is needed, as it does sound like you are wanting slot ports, then make sure the port does not interfere with mounting the driver.

Not sure if this answers the concern correctly, as I am not quite sure what the layout is in your trunk, so if my answer does not fit the concern, please let me know in more detail what you mean by port location.

Are you going for SPL or actual plan using this thing daily?

 

[SquishY 10+ year member]

Daily. My space is shaped kind of like the box in your sign, moble. The hatch is maybe like 48" at the back so if the ports aim into there then I could have the full 24" front to back. Really want use round ports.
