I added two tweeters onto the ledge just behind the seat above the seat belt holder, what a difference. I was never happy with the sound of the stock radio, the capacitor tweaking helped but the addition of the small tweeters, connected to the door speakers really filled the cabin with rich crisp sound. Installation was a cinch, just hide the wires and tap into the door speaker wire and stereo phonic ecstasy. I was a little worried they might blow but the summer is over and no issues. $$ input is low, anyone can install and you have the highs all with a much punchier sounding base.
