Score updates w/new port: Sealed up, mic on the dash.. 32hz: Driver door open, mic on the dash.. 32hz: Driver door open, mic on the dash.. 20hz just for fun: Driver door open, mic in the kick.. 32hz: Gives me a .5dB gain sealed up and a .6dB gain with the door open/mic on the dash with the new port.

Stock 80a rewound to ~120a. Nothing special. Keeps up though. Never go under 11.5. New port too, still haven't installed t-nuts. Audibly louder. Sounds even more so amazing down low, even though I'm tuned higher. I think it made a huge difference going external with the porting too. Old one has all the screws in it (6x6x10, made tuning ~45hz), new one is on top (7x7x10, makes tuning ~52 IIRC)

HeadUnit 4V question
J31Rob replied to Relyks's topic in General Audio - Can't find a category for your question? Ask here.
This pretty much sums it up. -
I did a TON of cutting to fit it. I had cut once before to fit the last enclosure which was ~6.2 before any displacements. This one is ~8 before displacements. The walls & woofers drop it to about 6. When I do aeros in my dummy baffle it will drop the ported lower.. but that is all a part of the grand scheme.

The lines represent where the panel will be mounted on the front of the box, the red smudges represent the panels the t nuts will be sunk into along with utilizing the 3/4" lip from the top & bottom panel for a good seal. I'll just seal the trunk off BEHIND the dummy panel so that it doesn't "unseal" the trunk per-say when I swap panels. Kind of a jank drawing but I'm sure you get the general idea.

My car seems to peak extremely low.. so my goal is to break a 50 by summer. If I don't do it with this box.. it's on to the next. LOL. The interchangeable port should help a LOT when it comes to metering, however. Gonna be able to try different aero port configurations, slots, whatever I want really. I've got some 10" I'm itching to use.. but haven't crunched the numbers yet to see if it'll work.

Started on the enclosure yesterday. Starting on the baffles: Done: Dry fit: 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.

Took some videos & scores before pulling it all out to build the 4th order blow through. 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. Before: Half way there: After: 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.
