Well, this isn't really "Alero" related, but I did take part in the build of this van.
I am a member of Team Audible Insanity, and my coworker (founder of the team) decided that he wanted to build the loudest streetable vehicle in the sate of LA. So, we got to it.
Equipment:
(1) Digital Designs Z2HV (clamped at 13,000 watts at .62ohm)
(10) DD 2500 series 15"s D4
(7) Kinetik HC16V
(1) 300amp Ohio Gen Alternator
(160) lbs of Second Skin Damplifier Pro forward of the B-Pillar
Box:
A Massive 4th order bandpass wall. Flat response from 30-80hz. Will literally play anything you throw at it.
Scores:
154.8db @ 25hz

A video complied by a friend of our first weekend out with the van. Cracked the windshield.
The second weekend out we split the roof.
This is when we welded a brace up top and started applying sound deadener lol.

This video gives you an idea of exactly how much air this thing moves. Note both doors are open.
