Whats the best audio system for a sportster?

 

If you have stock mufflers and don't ride over 40 mph the little mickey mouse ears make noise but will quickly fade out with the wind.
If you have an aftermarket fairing on the bike that blocks the wind will help some. There are aftermarket fairings that have audio you could purchase BUT you have to make sure you do not over tax the charging system as a sportster is not designed for that type of implementation.

 

Headphones

 

Your smartphone and a Bluetooth headset. I play Sirius XM on my Samsung Galaxy 24 FE through my Sena Surge helmet and my HJC RPHA 90S with a Sena 50S communicator. It sounds great.

 

OP is a spammer.

 

Cardo Packtalk PRO with JBL speakers in your helmet.

Keep it simple.
