yeah,stick with just the boom audio, if you do not want to purchase an amp.
not going to notice much, if any difference without the amp.
if i were you I would spend the money on an amp and keep the boom audio.
then upgrade from there if your not happy.
No, it is not plug and play, but it is a very easy to install unit. No need to run power wires from the battery. It can connect to one of the available12volt wires under a fairing. The existing speaker wires connect to it and leads from the amp go to the speakers. Very straight forward. I can provide instructions and diagram.
