Call up Sony/Blaupunkt/Audiobahn and I'm
sure they'd love to sponsor you. Maybe they can put a wall of 50 or so 6x9s in the back of your minivan.
Are you serious about a wall of subs in your minivan?? Perhaps you should keep reading...
Here's some food for thought. If you want quality stuff, keeping it under $1,000 will be -- let's face it --
IMPOSSIBLE. You mentioned, you'd be willing to spend 80 per sub. I dunno if you own a calculator or passed 7th grade math, but 80 times 10 (subwoofers) would be 800 bucks. That's not factoring in shipping that many subs nor the plenty of amplification and electrical upgrades you're going to need, amongst other things.
But if you're
really intent on doing this, I second Cam's opinion/recommendation. But if you're about show and want your subs to be stamped with some sort of logo on the cone, then those aren't for you. Let us know and we'll recommend some other stuff...
The bottom line to MY advice is this: If you're going to do it, do it right. When it comes to car audio, don't skimp out especially if you're going for the show-car-ness you've described. Have a plan as far as acquiring what equipment you want/need and how you're going to pay for it. Start researching, reading, etc. You'll thank yourself later.
