Right now I have 1 12'' in a band pass box........but I want to upgrade to 3 12's in a sealed box. How is this going to sound in my extended cab? Will 3 12's in a sealed box be better then 2 12's in a bandpass? Let me know what you guys think.

 

Most anything will be better than bandpass

 

I have 2 10" JL w3v2's in a sealed box from musicmooseaudio.com that run off a JL 500/1 and they rock. All my friends cant believe how loud it is for only 500 watts and 2 10's. I love it
