The system in the van was built three times
The first was with Phoenix Gold High Current 44 watt amps and Rockford Subs
The second was Original Profile amps
The third setup was with Profile SPL amps and subs (in which I was the director of technical development for Profile at the time)
The original 500 watt system did 150 db competed a few times with it
The system only got louder with the larger amps
Since it was a factory demo vehicle I normally would not compete with it; however I had a few grudge matches, set a few state spl records ( 155-158 db) and SQ awards
I really miss that van, was tons of fun; wish I had not ever sold it
The system did it all; was very loud, play extremely low bass
We played only music back then, no tone sweeps
Very good sound quality
The install speaks for it self
The thing was so reliable too; I would have the thing at some stereo shop every few days pounding on it with people in and out of it all day
The whole point was to prove good but inexpensive equipment done right could keep-up and even outperformed the popular more expensive brands
The Profile California series amplifiers (white amps with the lights) became the best selling amplifier for Crutchfiels (and that’s a lot of amp) at the time.
