Based on recommendations from others on this forum, I installed
Focal Access 165 component speakers a few days ago. They sound fantastic!
Replacing the stock speakers in the door and tweeters in the dash typically requires some time and thought, because a crossover is required. The stock speakers have the crossover built-in, while the replacement component speakers have an separate crossover about the size of a pack of cigarettes that must be wired to each speaker. This means running new speaker wire to the tweeters and possibly the doors.
You will also need to purchase or make adapter plates for mate the new speakers to the stock mounting holes. I bought adapters from
MJM Auto Innovations.
