I feel like a retarded little white boy playing it, but the true test for me to see if you have a *GOOD* system or not, is the song "Down for my Ni****s" by C-Murder. There's an instramental version that doesn't have the profanity for "safe" bumping if you look online... but it is THE test song.
It hits some low pass notes that when you've got a well installed capable sub, it will DROP YOUR JAW. When I was showing it to a friend of mine at Tweeter from the install bay, playing that song knocked almost an entire shelf worth of merchandise off of the shelf in the store, and attracted almost the entire storefull of shoppers to come out and see the car that was doing "that". They all thought I had some deadly JBL or similarly hyped set of subs too.
It was a single 12" in the most insane ported box ever (and was a brand name you guys wouldn't know)
Too bad they discontinued the sub
