Most 3.5 door speakers use a 2.2µF to 4.7µF capacitor for a basic high-pass filter.

You could take your door apart and look.....I mean, who would think that the capacitor size for a door speaker on a lower end nearly 8 year old car would not be clearly documented, right? I mean, who among us has not been out there with a soldering iron in our hands, tearing apart our doors looking to replace a capacitor.....
