No, I havent. I was messing around with some Sarah Mclaughlin songs earlier, but they're kind of old. I really need some new material to play with.
well, you can achive it by a number of ways. You could have alot of surface area moving (meaning alot of subs) or just a couple large subs in a large enclosure with a huge port. For example, my setup is just two 18's on 5kw (ive got 10k, but im afraid id cook my RE SX's that are in there temporarily)...and a 22 cubic foot box tuned to 32 hz and it peaks internally in the vehicle at 36 hz. My port is pretty huge, as you can see in the below pic.
