So, I recently picked up a 2010 WRX. It eats a little oil and makes a ringing noise but the guy I bought it from said thats normal for stage 2. He said that if I wanted to improve the car's sound that I should pick up a Soundaktor. I bought a couple on Ebay. I don't see anywhere that they plug in.
Where is the best location to install 2 soundaktors on a 2010 WRX?
