A:AnswerPersonally I do not do my own installations...if you purchased the audio amp through Bestbuy, I would let them install the device...usually its free installation. My installer did a fantastic job of a new stereo installation in my 2015 Chevy Silverado 2500. It was a Kenwood stereo so that said leave it to the installer...they know what their doing and what parts work with your install.
