Hi, I'm a new member. Just purchased a 2019 challenger scat pack 6.4 l , go mango orange. Traded my2006 SRT charger. I'm a BIG Mopar guy and currently own a 2005 dodge Ram 5.7 1500, A 1970 340 Duster coupe, previously had a 1970 Challenger RT/SE same Go mango orange, also had a 1987 Dodge Daytona Shelby 2.2 turbo, and wife had 1987 Dodge Shadow 2.2 turbo, and now, a 2019 challenger. Ok, I'm upgrading my sound system as I have done in all my vehicles. My question now is if the existing wiring harness might have a connector for a sub amp, even if the car was not optioned with it. My thinking is for Dodge to keep things standard, they would install a wiring harness set up for an amp and speaker connection even if the premium system was not installed. Any thoughts??
