a pair of those.
Helloooooooo custom install but awesome bass.
Awesome bass? Those are not free-air subs and would sound like crap mounted to the rear deck. Almost any 6x9 will be a vast improvement over the stock speakers. Install will be the same no matter what 6x9 you buy. It all comes down to what you want to spend.
IB can't be done in a car.
If you think otherwise, you're insane.
IB = ten times vas.
Trunk holds say 300-400 L (leaks like a whore too.... and that combined with the flexing = terrible sound quality)
So what driver do you know has a vas of 30-40 L?
If you went by the 4 times definition you might have 80-100 L Vas at most. But at that point you're better off going sealed.
But you're still insane if you attempt to do an IB install in a GP.
The time is just better spent driving your car.
