bass songs

I've just finished building and installing this box into a single cab 06 Sierra. Box is in place of the passenger seat ports^ sub forward. Head unit has 3 sub settings 80hz, 120hz, and 160hz(can't tell a difference imo) to a Clarion EQS746, an old audiobahn 8000T( I do have a boss ar2000m laying...

What are some good songs where the bass hits 30hz and below? I just built a new box tuned to 28hz for my American bass TNT 15. It hits very nice at 30 hz and below... PS: is this song around 30hz because it sounds great on my new system (the second time the bass hits)? Mambo - Tropkillaz
