Not so much. 143.6 @ 30Hz (Bass I love you), 147.4 @ 40Hz (Young Jeezy - Air Forces) at the dash sealed.

Here is the second one in better quality:

Here is my first video. A pair of Ascendant Audio 18 inch Mayhems in 6 cu ft boxes each, tuned at 33hz, powered by a single Stetsom 7k2d wired at 2 ohms. The system plays DJ Billy E - Beats 4 My Van. Unfortunately video quality is bad, no sound of the system can be heard, windows have too big area for a good hair trick. Because this is the first one - should be enough for start, videos will become better in future Here we go:

let's start from what car do you have? and which amp are you going to use?

I see in parallel thread 147+ from 18" BTL and Colossus II. Nice! Any others?

nice! any street installs?

Thanks for hearty welcome! As I can see many people have system components, electrical, but no SPL scores. That should be very nice if anyone can post some scores here

Are there any numbers? Street Classes, Street Max, Super Street and maybe Extreme? For example: Competitor name, vehicle, number and models of subs, electrical system and THE SCORE
