A Bronco would be a perfect SPL car. Im not talking about a higher tuned car, Im talking about a walled off fartbox.

Ive never built a straight up SPL car before, but I know a ton of people who have. I could get some people to help design it if its neded. If we could get a car to burp a 156, that would be cool.

Or we could do a groundpounder. Mach 5 Audio has the MJ18s for $116 each. Im sure I could talk to Mark at SSA and get a better deal on like 8 of them. We could open up and take donations. We could get Toby to hold onto them for us (if he agreed), instead of one of the kids on this forum holding a couple grand in cash. That could be big trouble. Btw, Those 18s are 600rms.

We could try some kind of bandpass with 8 18s that would probably be real loud.

If 8 18s would cost too much, we could do 4 18s in a groundpounder. If I could get them for $400, we could get an Orion 2500D off Ebay for $425 shipped. Run that thing at 1 ohm, build a nice efficient bandpass wall, and we would be set. Get some wood for about $100, misc materials for another $50-60, wire for like $130 or so (I got someone who might be able to help out), and a couple cheap batteries for $200 or so.

So for about $1,300 or so in equipment we could have a car walled with 4 18s.

And if it means anything, Ill donate my old JVC HU.
