I am looking for a way to install speakers on my '12 Street Glide's crash bar. I do not want to add the lowers fairings. I am keeping the stock head unit for now, and would swap out my RF PBR 300x2 amp if needed. I currently have Polk MM651 speakers in the fairing. I am not sure if I would need a new amp, could I run all four speakers off the two channel amp, as I am not going to really have front and rear speakers, just two left and two right?

 

You will need a 4 channel amp. Here is option for using headlight buckets on crash bar with speakers.
