hi all - please forgive me if i'm totally goofing terms here. car audio isn't my thing...yet! i currently have (i think) a "bandpass" sub? i think it's a 10". i'm not really happy with it. it's really really boomy, but in a bad way. i would describe it as "rumbly" instead of "tight". my girlfriend's newphew, who is into car-audio big-time (is sponsored, etc.) told me that it was too small. he said for that type of design to work, the box has to be pretty darn big. he mentioned some other type of sub that would provide the tighter "snappy" bass that i like. but, of course, i forgot what he said. so, any recommendations/comments are appreciated. thanks, ted btw - i noticed when i was examining this sub, that it may have been wired incorrectly. the speaker wire was wired in reverse. however, i can't trace it back to the amp without taking apart the truck (it was already installed when i bought it), so i don't know exactly if the wiring is correct on the amp side. is there an easy way to tell? i played some thumpy music and put my hand in front of the port, but it feels like the air is pushing out regardless of which polarity i choose.
