assuming the vehicle is capable of achieveing that. enclosure aside - the SPL jump between classes up to Extreme has less to do with equipment and more to do with vehicle reinforcement/seals. correct? obviously, the enclosure is key. but move the enclosure into different vehicles and you'll get different results.

true...those guys put tons and tons of work into their cars to get as less flex/vibration as possible. They also put just as much into the box

The equipment will be capable of doing a high #, but the vehicle could hold him back

if/when i do a dedicated SPL vehicle - i'll probably start with something from the 50's when steel was thick and hammer-proof and the vehicle was simple, dashes were metal, etc. it'll be a single sub. like a 50's wagon or pickup with a blow-through. i think people make a lot more work for themselves by using modern vehicles with metal so thin you can flex it with your hand. further, older vehicles had more curves - curves are stronger than flat expanses.

He seems very butthurt about this subject for some reason. I'm not even sure why this argument is occurring?

i like the idea, but not the effort. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif i am ok with an SPL vehicle weighting 7,000 pounds. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

okay while on this subject lol... whats the loudest trunk setup to date with the rear seat up and not down with no blow through to the inside cabin?

window height/angle and depth of dash also play a big part on how a vehicle meters sealed up.

My van has a big *** windshield and very deep dash, that's why serious SPL competitors use other versions. I don't chase numbers so it's all good.

The Hoe is a "walled" vehicle per dBdrag rules since he's several inches above windowline, but yes it's not a true walled vehicle.

He and I got off to a bad start, but I still respect him for coming out and demoing/competing.

That would be a fun number to chase for haha.
