So I'm thinking about buying 2 12" subs for my G. But since I'm not very familiar with this kind of stuff, I have no idea where to start! anyone want to give me suggestions on what kind of subs I should get? and to install subs, do I need to get a deck?...

 

It really depends on what sound you're trying to achieve. Do you want the neighbors to hear you coming from down the street, or do you want to keep most of the sound in the car. I think 2 12" is a bit much.

But like I said, what sound are you trying to achieve?

 

Put in one 10" rockford fosgate T2 sub with a an amp that is capable of pushing it and you will not be disappointed.

 

Get one Kicker L7 12" and a 1000w (KICKER ZX1000.1) amp! You wont regret it!

 

+1 on Kicker. I had 2 10" Kicker CVR's in my truck and it sounded really good.

 

I've got 2 10". Check out my pics at my garage.

 

1 12'' is the way to go in my opinion.

 

Ok in my opinion kicker sounds too dirty, the bass quality is crap but there loud. I have one Rockford p3 12 with a ported box and that **** shakes my house. Downside is I had to take out the spare tire to make it fit lol. That's in my opinion the best bang for ur buck the sub cost me 140 the amp is alpine pdx 600 digital I think it's the best amp for 230 bucks it pushes out all 600 watts to 2 or 4 ohm woofers, The box cost me 20 off a friend but usually will run around 80, if you really wana bump get 2 of these! But the cost will be much more. Oh ya and dynomatt your trunk it sounds bad from outside
