If I were u, Id go with sum high end woofers, the GS isnt an cheap car, so you'd probably should get sumthing that matches its class. Just my opinion. Also get an custom build if u got money to spend on the project. My old car I had 2 JL Audio w6s with 2 JL Audio 500/1 slash series amps with an custom box and rack build. Also dynamatted the entire trunk, helps the sound stay in the car too. I dynamatted the gas tank lid too. So no rattle at all. Just think it would b more classy with an custom build. It all depends on ur budget and taste for what sound u want. But thats my 2 cents, goodluck with this project.

ive had several subwoofers in this car and i found that the jl audio w6 is probably the best way to go. also i dont recommend slapping some box or hide it in the corner. The car is expensive so do it right get a fully custom box done. search my name and u can see what i have in my trunk. If your looking to save some space, go with the polk mm series they are a lil more shallow than average subs and go loud and sound good.

Listen to Rozay604, he is absolutely right. Putting a box in the corner of your trunk 'sucks' because the sound waves have to travel through the GS's body which is very thick with materials; the car was designed to cancel out noise. Putting a sub in your trunk just cancels out the sound and with that setup you have to crank your sub way up just to hear it which at that point the sound is out of alignment, distorted, and muddy sounding. Rear deck lid is the only way to go; unless you remove your rear seats. 
I went through this whole process myself starting with the box in the trunk idea and let me tell you that setup never sounded right. I got the most powerful JL amp with a 10" JL sub and it was no where near what it should have sounded like. I insisted on the rear deck lid idea which meant they had to build an enclouser there but once it was installed, night and day. There was such a dramatic diference with clarity, punch, and tone.
Warning: If you have a rear shade you will most likely have buzzing vibration noises, 'I had to have mine removed'
If not go nuts...

I have the Alpine Type-R 12" in a box in my trunk -- takes up more room then I wanted but I don't regret it one bit... sounds great -- but it does rattle the gas tank and the trunk a little...... but it sounds good and CLEAN

Dont tap it to the sub out. the crossover point in the gs is horrible. The best way is find where the factory amp is and take the left and right rear speaker ch bridge it into a loc. That way u get full control of the crossover from your amp. Also make sure u tap it before the factory amp not after.

@ ACJ- It doesn't sound clean when your gas door rattles like a hoopdie with 3 12's in the trunk! 
I was just talking to Rozay about finding a solution to this. I'll keep you guys posted if I do.

I am tapping the front woofers. I know I can get at least a 100hz clean tone to my sub with my current LOC. I am thinking about getting an Audiocontrol LCQ1 too to see if I can get a better sound.
Unfortunately the rear deck solution limits what subs you can add unless you do a major mod. I am just going to add a couple of 12" Arc Audio Flatlines or Arc Audio Blacks (Pure SQ subs) to some boxes. I have one now, but you are right because of the sound insulation, hearing and feeling a sub can be a little difficult, but I don't want to be limited only by what I can add to the rear deck. Also, I want to keep this stock looking as possible, because my vehicle is a lease and goes back in a little less than three years. I will be powering the subs with a JL Audio HD1200/1.
