Lol.
4 15s, and sounded great. WOW.
I have yet to hear anything over 150db, that sounds great.
Why does people think SPL subs is suppose to sound like the Cheapest equipment distorted to the max.
I'll ask, why did they sound great?
How did they sound GREAT? Well the bass was clean and precise.....and you can't ask for much more from 160+db 30sec average set-up .....basically it didn't sound sloppy....and actually sounded better than a few "well tuned" lower 150 vehicles i have heard
