I may as well drop this on you guys first...
I've never built a dedicated SPL vehicle. With the work I've been doing with Stereo Integrity on the Audi and the responses we were getting during the build and, more recently, after taking to a "show", people are going nuts.
The entire time I was building that thing I was told (at damn near every point in the build) that "it's not going to work"
In regard to the sub:
"Not enough airspace"
"Big subs are slow and aren't accurate"
"The motor is going to drag the ground"
"It's going to pick up road debris"
and so on...
In regard to sound treatment:
Guys saw I was packing empty voids that I couldn't apply deadener to with mineral wool. "You can get the same effect with properly applied deadener"
When guys saw I was doing 100% coverage: "That's a waste. You can get the same effect with 25% coverage"
In regard to the 3-inch wideband drivers in the kick panels:
That's too low.
There's too much separation between the mid and tweet.
Female vocals will suffer.
In regard to the fab work:
"Those birdshit welds will never hold" They were seeing welds we intentionally built high so we could smooth them down after making three passes on the bottom of that 3/16" plate and three passes on top.
So yeah...this build.
I had a budget of less than $5,000 to get a daily driver that I could build. With the back messed up it sucks getting in/out of the Chevelle or El Camino.
I picked up a 2004 Scion xB. This is "special" release series vehicle. Has a "Hot Lava" color.
This one is also on some BBS wheels with stretched tires and air ride because apparently THAT'S what I need.
I didn't really want the airbags, but the thing drives nice, has great power (as good as to be expected from these things, anyway), and has AC that works.
It had an old Pioneer AVH-X5500BHS from 2013 in it along with a small amp and JL 10W1 in a sealed enclosure. The sub didn't work. I put in a Stereo Integrity SQL-15 in a 1.25ft^3 sealed enclosure that I had sitting around. Sounds decent for a commuter
I just installed a Pioneer DMH-2600NEX in the thing. Nothing spectacular, but it has CarPlay and Android Auto and MUCH better phone calls than the old unit.
So I have some parts (steering wheel, clock spring, and cabling) here to swap the steering wheel so the thing has steering wheel controls for the radio.
The airbags are kind of a PITA. There's no way to know how the thing is sitting and no frame of reference for anything in the vehicle. There's a control pad, but no pressure gauges to tell you anything. Have to hit the switches and get out to take a look at the thing to see if it's right.
So...I guess I'll drop the audio plan here.
Four speakers will be in front of me.
There will be 8 custom built carbon fiber 24s behind me.
These 24s will have 38mm one way linear travel (that's 70% BL, or motor force). They have over 100mm peak-to-peak stroke.
The 24 that went into the Audi? 30mm one-way linear travel.
The 24s are rated at 2,000 Watts RMS. Since I'll be using a Sundown Audio SALT-12 to power the 8 24s, and since it'll make up to about 24,000-25,000 Watts when wired to 1/2 ohm, these 24s will be seeing about 3,000 watts each.
I know people are going to say that I can't package 8 24s in that little-ass xB.
I know they'll say that I don't have the airspace and so on...
I also know that 8 24s with 4 inches of stroke are going to move a shitload of air. It's going to be violently windy.
So the initials SI are commonly used to refer to Stereo Integrity and it's a common thing for SPL rigs to get names.
Since it's using SI subs and it's going to be a windy bastard, we're calling it Project Siclone.
