Enclosure design for 2 Sundown Zv3 12"

13 posts in this topic

This will be in a scion tc 2006 hatch back.

Subs: Sundown Zv3 (1500rms) D1's wired in series to 1ohm

Amps: 2 Skar 1500.1's strapped

After box rise I want to be at 2 ohms or less

Max dimensions:

Width 41

Height 12.5

Depth 21

Currently I'm tuned to 27hz on 2 sa-12's and I peak at 39hz which is where Id like to stay for a peak. I'd go to 29 or 30hz MAX

I am open to aeroports or kerfing or slot port or whatttever.

Thanks for your time :D click the link in my signature if you want to see the current box

Looking at your previous box it seems to me that when the hatch is closed the ports firing back are almost sealed back there, I guess that changing the port direction up (even with a turn) with that design would help.

I am weary to do a port up because I tried it with my alpine type x and it sounded like shit. Even tho they only have an inch of space it sounds really good. I think the best idea is to take an inch of the depth instead of shooting the ports up

If you want sub up/ports back I would do something like this:

I would cover one of the 4" aero ports for daily and use all 3 to get loud.

thats looking sexy. I could even fix my current box to look like that. Do you know anything about putting subs as close together as possible to sound best/loudest?

Bear in mind that this is not a design, just a way out for the ports without taking much net volume. Yes there's plenty of infos around the internet about the increased acoustic power but I don't think that 2" more or less will change anything dramatically.

Step your game up to the 4500, son! this box will be perfect for that!

That was the original plan but I would need another 2 runs of 2/0 and a D3100 in my trunk, there's unfortunately not enough for a D3100, skar 4500, and two alpine amps plus my 3 other batteries lol

Yes and I don't compete but I would like to burp in 150 (60hz) and daily at 145 (under 40hz) with the sa-12's and skar 1500 I daily at 142 so I think with the Z's and two skar 1500's strapped it's plausible
