You guys should seriously consider a TSB for this issue. This seems to affect many proud jeep owners. If there is a TSB already, I apologize for not seeing it.
I bought the original Tazer JL that works on both JL and JTs, but have never used it or connected it to my Jeep (Only have updated the firmware to the latest 11.2.5)
Selling for $150 shipped (CONUS)
I also installed the Alpine SPV-65-JLT. Also from Crutchfield. First, I followed the instructions to connect the speakers as stated by the Alpine instructions with the connector that matched the new speakers (just one, the one that went to the tweeter) and was like "meh" with the sound...
If you don't like it, you can cancel as others have stated. Otherwise, change the password provided when it was registered, and select your PIN (which is required before sending the commands you listed)
