not very well. I actually stuck pioneer 6.5's in there and they still didn't fit very well because the stock ones are shaped differently. You can make anything fit in there it just depends on how much time you want to spend on it.
"yall" where are you from, i thought only texans said that. if this is true we should talk, let me know(i'm from austin)
most speakers have a range of what they will fit marked somewhere, but its not very reliable. it really just depends on the consruction of the speaker. the only real way to find out is to try it. good luck.
are you doing this your self? because most shops waont do it unless you buy it there or pay them by the hour as apposed to paying for the install.
