As of this moment i will be running B2 audio lithium batteries, 4 x 15" Ampere audio 4.0 subwoofers and 4 Ampere audio 9.0 TFHE amplifiers. That is the game plan at this moment. Will run a pair of amps strapped per pair of subs. Should net me 40k watts at 14.4v or so easily. Alternators will come from Singer alternators. Mike is a good guy. I have dealt with him in the past

Nice, that's some serious power. I've heard good things about Ampere audio stuff. A guy on the SMD forums runs 6 of the ampere 3800's on 6 crossfire 18's.

 
Ive known the owner of Ampere Audio for many years. Great guy. Those 3800's come to life on 18v I can say that lol. ive seen over 14k watts on a pair of those on 18v.

Will the glass stay in this thing at full tilt?? Does the concrete offer better sound production. I know nothing. Quite a project man.

 
Main goal for a SPL system is everything needs to be rigid. Stiff. Eliminate flex and score goes up. This was my experience with my last build anyways. The concrete wont flex. Rock solid surface. But you kinda have to do the walls and all out of wood to form shape. So the reason I did 2x4 cross layed again is strength and rigidity. I will run thick fiberglass biaxial mat on the floor of the enclosure so I can sand and polish it smooth. Then do everything else I have to do in the enclosure. All corners rounded, Tubes mounted and polished out same as the enclosure ect. I can say this. I will have A TON of sanding to do inside this enclosure. Hours and Hours. Doors will be fixed up and door panels made with no speakers in them at all. Flat surfaced polished out as well. Floor will get coated with sound deadener as well as roof up front to windsheid.
 
The glass should stay in it. Might crack but shouldn't blow out.

I remember Myth Busters "The glass should stay in it. Might crack but shouldn't blow out." Do this!
It was funning to watch, but they never could Blow out the Glass.

Its been done. Mainly only happens with the glue bead gets a tiny break then just keeps getting abused. Then fails completly
 
 

I feel for anyone that lives in a 3 block radius from you, once you get that system going.

Couldn't agree more. With those kind of sound systems, I would be watching my "6" for people following me, and once they know where I live... unless you park in the garage, that's a different story, but they'll still know where you live. Keep your eyes open, and don't doubt me because there are people out there like that.

Already dealt with it. First person who thinks its a good idea to come onto my property uninvited is going to find out real fast. One neighbor already tried it. Did not work out good in his favor. But mine will be garage kept.

This is is something that I don't totally get, especially at the build levels you're going after.   But I do enjoy seeing the progress and the technology behind it (even if I'll only maybe understand a third of it.)

Edit: Double post...

I live around people like that. Literally the most obnoxious people on Earth. Sadly the law protects them while they annoy the neighborhood.
