Has anyone added an aftermarket amp and kept the Beats mids/tweeters? I'm thinking of upgrading the system in my '17 R/T, and I know I will be using the AmpPro to get my clean line signal, and I will be adding a 4 channel and mono amp. Obviously I will be making a upgrade to the whole sub part of the system as many have done, but I was wondering if anyone had experience with an aftermarket amp on the stock high's.
