I got two pioneer IIMP tens in my firebird right now and they do a great job but i want to upgrade to something a lot louder, and with more push. Im thinking of either going all out with 3 tens, 2 0r 3 twelves, or a pair of fifteens, i was wondering what size, and types of subs you guys would recomend, and if anyone has plans, or the dimensions, for the back of my car thanx

 

If you are looking to go a lot loud but still want clean sounding bass, I would recomend going with two 12's. There are a lot of subs to choose from, it all depends on how much you are willing to spend to get to where you want to be. Also what kind of amp are you running now? Amps are the lifeblood of your system, if you skimp on the amp you won't get the sound you want. So my first suggestion is buy a good quality mono amp to run these subs with. As for loud subs, JL Audio W7's are loud!! Very pricey though. I would have to have an idea of how much you wanted to spend before I really could recomend anything.

 

Go with the 2 twelves. I had one in my 91 firebird with a 1600 watt amp I can't even imagine 2 of em in there. And they fit nicely also. 3 u would run into problems with the setup(no where for t-tops). I had 12' rockford punch he subs and they sounded great go with 2 twelves man its more than enough.
