Q: What speakers will fit in my door?
A: Any size can fit if you have the time and money. As for what fits into the stock door locations with only minor drilling or trimming? Most 5x7s, 6x8s, and a few 6x9s will fit in the doors. Component speakers will fit as well with the addition of a plate to hold the mid.
