Hey there, I was in the same boat and took my door panels off to find the speakers are EXTREMELY shallow which doesn't leave you many options as far as aftermarket upgrades without having to build some kind of kick panels. I went this route at a local stereo shop and was very pleased with what they came up with. I was able to drop a set of Focal seperates in the doors, and they sounds incredible. If you look on Crutchfield they have a fitament guide that can direct you towards something that my be able to drop in. Good luck.
