I have a 18 Road Glide. I’m looking to start buy audio components over the winter. I’m looking at the Vega amp. I know nothing about amps. I’m going to start by doing and amp and front speakers. Eventually I want add saddlebag speakers. I was looking at buying the b54 four channel amp. But I saw that Rockford Fosgate recommend running the 4 channel amp 2 channel selection. So am I better off buying the B-52. Like I said I know nothing about amps so I was assuming for channels equaled speakers.
