SinisterSound gives you the best aftermarket audio system upgrade solution for your Harley Davidson motorcycle. The SinisterSound promise is not the empty hype you find from others in the sound design market.  We have meticulously performed many years of research and development. We test our speaker system designs in the environments they will be used; on motorcycles at typical road speeds with normal ambient noise. We do not just reconstitute car audio. Our fairing speaker & amp system alone is a major upgrade and will be heard, loud and clear, even at highway speeds. Your music will sound full, dynamic and crystal clear at high volume. Unlike other systems that start introducing distortion in an attempt to be heard during normal riding conditions, our speaker systems have been designed to play loud with ease. This is important for many reasons. Available amps for the motorcycle audio application, limited charging systems, loud pipes and other competing sounds are just a few of these reasons. Often just two speakers have to get the job done. With this understanding, we tune enclosures when possible, often resulting in more than twice the mid-bass as other systems. We simply provide our customers with the best motorcycle speaker system that sounds amazingly clear and powerful.
