Scale Subwoofers

Whats the biggest size of subwoofers? and how many would come in a kit? Im filling the rear of my van with speakers and a few hydros and i need some pricing info.

Thanks in advance.

If you search some boomers, I've a URL for you:

It's made for 1/18 but I have the same & I'll put them on a 1/24 kit. On the web site there are too amplifiers.

For your van, maybe 6 boomers and 3 amplifiers would be a good installation.
