Hm, you bring up a good point that never crossed my mind. Not sure if you're familiar with the interior of a 3000GT, but it's relatively small (two door hatchback with rear sits big enough for only a child or two) and the rear speakers are mounted to the sides of the rear seats. They are just behind the front seats, the rear driverside speaker is maybe a foot away from my head when I'm driving. They face toward the front, directly behind the rear seats is the trunk which is where I plan to put the sub and an amp.
Now I've been doing a bit of research on running only front speakers and I'm seeing a lot of different answers, honestly I am one of those people who prefers to be surrounded by music, now I hear that the soundwaves should reverb around in the car and make it sound like this with just the fronts, but I feel like rears would still add to it. On the other hand, not installing rear speakers would save a ton of time, getting to them would require me to take half the interior out.
As for your sub suggestions, that thing looks like an absolute beast. The only concern I have with it is that my stock alt will not generate enough power for that sucker. Hell one of those alone would probably be too much for my car.
My total budget is what the price is at now, just about $1k. I just bought this car not too long ago and I'm a relatively broke college kid, so even $1k is kinda pushing it.
