[QUOTE="gleep52, post: 8708827, member: 640862"] I put in a Kenwood carplay head unit years ago and it's worked fine. I have the[SIZE=4][FONT=arial] JBL system and I use a [/FONT][B][FONT=arial]Metra TYTO-01 JBL Amplifier Interface Harness to go from high level speaker outputs on the kenwood HU to the Metra harness which then goes to the factory radio harness and feeds into the factory amp under the passenger front seat.
