Hi.. I have a WRX 2009 without technology package.. I have this in mind but I am not sure if what im doing is right or wrong ...
Keep the same Head Unit
+ ADD a Amplifier
+ ADD/CHANGE the 4 speakers in the Door
+ ADD Tweeters
You guys think this will be decent enough ? What size speakers fit in the back and front ? I want to start looking into speakers but dont know what size to look into ... Any recommendations ?
