hey guys, just wondering if anyone else on this site is a subwoofer nut.
when i first got my celi before i could legally drive it on my own i had already put in a pretty massive sound system which set me back quite a damn bit. got remote ignition alarm installed so i can turn it on from my bedroom lol, leds that change colour,pattern,speed etc.
anyways just wondering if any other ppl are into competing in spl
i cant remember what my best DB rating is but i do remember hitting a 137.2 or something.
talking to a spl specialist he reckons i can get 145db or so if i get a new box made, and thats whats holding me back.

yeah well i was talking to a specialist about getting a box built. this guy is crazy, he holds records australian titles and everything, hits over 170db. crazy as all hell. a cool thing about my car is under the head unit you will notice lil knobs. thats a bass generator. you can change the sub settings and there is this red button, when pressed sets the subs off, its so fun to scare ppl with.
im also actually getting 2 more vibe subs today for $350aud they are the black air series tho, but still powerful. hopefully i can get a box made to fit all four subs in my car with maybe 2 of them inverted.
god bless sound systems.
