I have a 2018 SL with ride command. I want to add the SSV rear speaker/ pods. I did some research and found a mostly plug and play kit from Xtreme Tunez ( formerly Sling Tunes). This kit has a upgraded amplifier and all the wire’s needed for the front and rear speakers. Is anyone on the forum using this kit? If so what are your thoughts on it? I have tried to contact Xtreme Tunez by email and phone to ask questions about there SSPowerPack kit, but haven’t had any luck in contacting them. Any information would be appreciated.
