ok after installing my speakers in the front and installing new speaker wire for the rear doors (routed pretty easily through the stock rubber tube from doorjam to door!), I have some questions regarding the rear doors.
The stock "Upgraded Speakers" look like standard 5 1/4" speakers.
What aftermarket components, coaxials, or mids have you been successful installing in this location for a '02 WRX ? What modification (if any) did you have to make?
