I have just finished upgrading my 2006 prius audio system. I had the stock JBL system and I changed it out for: 1. Pioneer Avic Z130-BT 2. JL Audio 700/5 Amp 3. C2-600 JL component speakers and tweeters 4. 2 JL 10 inch subs The system sounds AMAZING but I was wondering if I 1) can remove the stock JBL logos on the tweeters and 2) where can I sell my old headunit? Thanks!
