Hi, I used eclipse speakers (fujitsu ten). 7 x 10 would be a tight fit. You could probably fit them, however depth would be an issue. The 6x9 only have about 3-4 mm gab between the magnet and the window glass when it opens. Bringing the speakers forward with a bigger baffle would cause them to interfere with the door trim. 6x9's give excellent bass and clarity. Can't see why you would need more. thanks for the info !! i just happen to have a set of 7 x 10 in the shed i thought i could use them instead of them gathering dust good try anyway :(
