lol, alot of the movies i watch have crap down to 10hz. one movie has this scene where this chick is walking through the woods and all you hear is crickets. but then this crazy rumble starts up. so all you hear is crickets and all you feel is ur organs begging for mercy. when i first played that movie i thought i blew my subs. alot of drivers make all kinds of funny noises below ~25hz
Your JBL is not a bad amp, should be able to get a few bucks for it.
