Hi guys, I recently upgraded my Camaro 16 1SS to the 17 1SS 1LE. I had a sub and amp installed in my 1SS 16 while maintaining my stock system. After having it done I had a weird sound coming from the sub while driving my car and later found out the stock system uses the bass to make the exhaust sound louder. However the 1LE looks different so the cord I unpluged isn't there in the 1LE. I tried to explain what happen last time to the installer and he didn't believe me. Is there a diagram or some purple dinosaur barney style instructions to show them. Thanks for your help.
