PAC AmpPRO AP4-GM61 & PAC APH-GM02 AmpPro Speaker Connection Harness

PAC AmpPRO AP4-GM61 Aftermarket Amplifier Interface & PAC APH-GM02 AmpPro Speaker Connection Harness. These are used in tandem (one behind head unit and one behind seat near stock amplifier) to retain factory head unit, stock amplifier bypass, and retain steering wheel controls. No need for any manual wiring, keeps factory plugs & connections when adding amplifiers and speakers / subs. Easy installation and super clean interface. An additional bonus is you keep all stock audible signals (ignition, blinkers, etc) and can even modify the volume. Personally I loved being able to bring them all to near silence. Selling as a bundle as they are both a must for installing aftermarket stereo in 2014 - up GMC cars / trucks. Paid over $520 for the pair brand new less than a year ago. Perfect working condition, can even send over proof of purchase for warranty if needed. No issues, all wiring / harness still in as new condition. Selling because I sold the truck and removed system.
