Bought an Atomic AT3000.1 and scrapped the ONX1500.1s. The Atomic HATES the 8v preouts, however. Going to have to find a solution for that. Amp won't even play at high volume..
Box is being rebuilt ASAP, going to try a 2:1 4th order blow through, sealing the trunk off. So don't mine my **** hole throw-together install I've got there. This was for testing only.
Here is a garbage video I was trying to get of the SA10s pulling a box with 6 L brackets off the trunk floor, no luck though. You can tell when the song drops to 25hz though. Frames get all shaky n ****.

Oh and I did a 143dB driver side door open, mic on dash. 141.3 sealed up, mic on dash with the MB Quart DSC1500.1. Never got to test with the 3k as it wasn't working when the meter was here. Will retest this weekend before ripping it all out & doing the 4th order.

Did I mention I'm flat from 28-41hz?
Did some work this weekend.. pulled it all out to prep for the new enclosure. Got the body saw out & did some work in the rear deck to fit this new beast of a box. My poor car hates me. I'm getting new suspension in the rear to handle the added weight too. I gained close to 3" just taking it all out so I figure I probably oughta handle that.
A little testing before taking the existing setup out.. this score is w/the 4 SA10s @ 1 ohm on the Atomic 3k in ~5 cubes @ 33hz. Driver door open, mic on the dash.
Half way there:
A little bit of pretty work to be done to the rear deck still.. but it'll happen when the enclosure goes in & I either glass it in or seal it off w/wood & wrap it.
Here is the new box design:
Port will be firing into the cabin of the vehicle & sealed off from the trunk.
Starting on the baffles:
Building sealed chambers:
Back wall added:
Bottom added and sealed up:
Sub cutouts are just a tad too small, didn't think to check that before hand lol. High grit sandpaper or a small runover with a router should do the trick. Gonna wait to put the top on for ease of dropping woofers in. Its not impossible to add/remove them with the top panel on but its just gonna be 100x easier with it off.
Going to try a port with 2x2s first, then gonna play with different size aeroports with a removable front baffle. It'll be interchangable for music/SPL/whatever.
I don't even know why I update this.
that 2:1 ratio must be sick I wish I had enough space to spare to do that with my 18.
We'll see how it works. Excited to put the interchangable baffle on.
Nothing yet. I've not even started to add the port. Gonna do it with 2x2s first then build a dummy panel on the front with the ability to be pulled on & off with some simple t nuts or wing nuts.. something. Then I can try aeros, different size slots, whatever I want really.

Just build baffle after baffle until I get musical, SPL and the lowz SPL.
