Sundown Z v.4 12" Prototype In-Car - YouTube
Quick video we did on Derrick's phone last night. Lighting isn't fantastic but we wanted to get something up as soon as it started playing. I'll have to work on getting another with my HD camera and some better lighting.
SAZ-3500D v.2 (original prototype) on the Z v.4 12" D1 prototype woofer -- single 6" aero-port box tuned to ~30 Hz in a box around ~3 ft^3 or so. The VW has a stock alternator and an XS S3400 battery so we went big on the box to avoid pushing the amp hard enough to drop voltage super low and clip (we had clipping / 11.5v drops in the smaller box).
We were getting some very high excursion levels; not to the point of maxing out the suspension but quite a bit beyond what our older platforms are capable of. The video doesn't show this the best so stay tuned for more videos. The goal with the new frame and suspension platform was to create drivers that you don't have to worry about hitting suspension limits -- and that is what we achieved. Even in a big box with a ton of power mechanical stresses are almost non-existent.
Jovanni drivers this car daily and is not easy on it so I consider it an excellent durability test !
