I Recently took a look see.
Red was with the box pointed at the rear window with microphone on dash
Green was generic mic @ mouth in ‘big’ room
SPL is not calibrated (theres a Peq/filter @ 20 hz to protect drivers)

Nice, you went from a F3 of 40hz to a F3 of 25hz.
Hence, cabin gain or transfer function in vehicles.
Look at the gain at 20hz!
This is why BP4's can be tuned between 60-80hz and still get 30hz performance in a vehicle.

I cannot believe someone would pay $600 for 2 x 5" (2" x 8" drivers) subs.

It has the factory fender system. I have 2 shallow mount 10s I can use but I think I’m gonna use the 18.
That's what I assumed on Crutchfield and other audio sites.
You removing the back seat for the 18?

If I commit I would Just remove the driver side rear seat and point the sub at my back. In this small space I would use a chebychev qtc of 1 which, At this point with a fresh driver is 115L. According to website specs, it would be a tiny 39.5L after break in. If I go the compromise route, I can fit the tens under the passenger side and fiberglass the box under the entire bench. I have 2 Polk db+1042 svc. They are shallow mount but they prefer a bit of space. I think I can get at least 1.5cf. The benefits of the 10s would be much cheaper build and preserve the stock aesthetic. If I run the 18, I have to upgrade the electrical significantly to accommodate either a ds18 fr-5k or a stinger mt-4000.1. Plus the mids and highs amp. I keep thinking about how cool it would be to put a sealed 18 in there. it would be crazy on proper wattage. But maybe I would be happy with the 10s and preserve the truck! I suppose I could always start with the tens since I have both. First things first though, I’m going to dampen the entire truck with butyl and foam.
Last generation Tacoma . Kinda intersting to see what happens in the electrical impedance. I don’t know what the cabin resonace is in this ?? (Something is affecting ~105 hz)
I’d like to try a box that isn’t so ‘overdamped’ at the low frequencies and mess around with REW

GTW, have you seen this video?
Frontier videos are hitting my queue now.

I had a Mechman 250amp alternator in my F150.
These shallow mount 15's are in 3ft3 sealed total.
I miss that truck. I won't haul crazy stuff like mulch in the Crown Vic. I have been window shopping 2019 and up F150 SuperCrews with Coyote V8's. Been debating if I will purchase 4wd or not. Both my trucks were 2wd. The F150 came with a 3.55 LSD axle. The Ranger came with a 3.45 open axle and I added a 3.73 LSD axle from an Explorer. While I had the bed off, I added a rear sway bar from the same Explorer. I'm kinda mad that I never took any pics of that axle swap and sway bar installation.
Cool install I’ve seen those polk momos before. one of the only shallow mount 15s ever made with nice xmax too. What did you think of them?
