Re: About the 07 sound system
There are different levels of sound systems in the GTs. I have the Shaker 1000 in mine, and it kicks ***. 1000 watts with 500 of them (I believe) pushing two 10s in the trunk. There's also the Shaker 500 which also sounds decent, but doesn't come with the two subs. Then I believe there is just a base model, which probably does sound a great deal like a transistor radio.
