2006 Acura TSX! That's right, it fits 2004-2008 Acura TSX, it's so hard to find information on our cars for door speaker kits, so I decided to help anyone who is confused like me. Standard floor holes in the door then I took a marker and marked 3 holes in the speaker mount to the door. Then I took a 1/8 bit and drilled through all 3 marks. Then I took 3 self tapping screws and then screwed them into all 3 holes. I then took the sealant and rubbed it around the mount so that it forms a rubber pad as it dries to keep it from vibrating. Then I put the speaker back in. Speakers I used ((Alpine Type S S-S65 model, they are size 6.5)) - Then screwed on with 4 screws, fits well enough to the speaker's hole mount. - Then your kit to reassemble the door. Then enjoy your amazing new sound, they sound so much better than stock speakers and you don't need an aftermarket amp. The standard amp feeds them well. I've posted pictures of items you may want to purchase if you don't have them. I bought everything here on Amazon. Many Thanks
