Vented Box In my truck right now i have 2 12" JL w3's with a planet audio amp in a sealed box.My truck is a regular cab so room for the subs is tight so im guessing the subs are choked on air space.What im asking is if i were to take one of the 12's out and build a vented box with just one JL w3 with a 250/1 JL amp would that hit harder?
OR
2 10" W3v2's in a vented box?

I was running two JL 12" w3s in a sealed box in my bronco, they were very clean at low levels but could almost bust the windows when you cranked it up. I now have a 10" w3 in my tahoe in a sealed box. It is not as loud, but very clean. Since you're in Houston, call Custom Car Stereo, they are the best in the business and will be able to answer all of your questions. Hope this helps.
also i was wonderin would it be worth it to just add another sub to my box? and have 3 subs? i know i would need a new amp so what would be yalls recommendation? 500/1?

In a truck you really dont have enough room to go bandpass.
Porting a box requires you to tune it to a certian frequency. Your over all frequency curve will be more narrow but in theory you will gain a +3 db. JLs sound the best in a sealed box. Are you sure you have enough power on these subs?

You want to tune the box for the type of music you listen to also.
