I got these 4 compitition 15s in the trunk of my chevy impalla and a 3000 watt mono class d. Its loud but my trunk aint popin like my boys. He got 3 12s it his box chevy off 2000w.
My subs are full sealed the box is huge and heavy got my back end ridin low on tha 26z. my bouy at the shop say its just cuse a 12 throw bass better than 15 and he run 10s tho.
eryone no the smaller the sub da betta. I run 8 in subs and dey hit like a m0thafucka. dey blew my window out n erythang.ditch dem 15s and get u a 6.5 inch sub and ull be bangin.
No but seriously, I don't really know what to tell you. You could go ported to get louder, but make sure the enclosure is built to spec. 12s do not throw better bass than 15s I don't know what your mans smokin. Do you even have the electrical to run 3000 watts? I'm guessing no.
Kickr Compitition 15s on my Nitro 3000w 2channel amps got that power My cousun had that same amp but in the 4channel makin his 4 12s slap. was enouf to burn thme subs in 1 week id tell anyone to get that amp its ah killa
is the box made out of cardboard? are you perhaps related to snow? if so ur s.o.l. when you slap it does it make a noise?
on a serious note, ohm load? are all the subs hitting? perhaps one isn't hooked up, maybe one is hooked up backwards? take it all out, take ur time putting it back in, make sure you put a kicker sticker in the back window.
