Review: Top Lautsprecher zu einem Top Preis! Leicht zu befestigen! Sieht gut aus und ist leicht zu bedienen! Nutze die meiste Zeit meine Musik auf den USB Stick(war enthalten)! Verbaut an meiner Road Glide! Nicht an der Batterie( Dauerstrom) angeschlossen, sondern in der Lampe da ich wollte das er nur mit der Zündung läuft! Lautstärke aussreichen, fahre nicht mal mit der Hälfte! Empfehlung für jeden der Musik beim Biken möchte!

A: yes it will just connect it to battery on your bike

**Q: I do not ride every day I am worried this will run my battery down**

If the motorcycle does not start and you are listening to the stereo, with a 20A battery capacity, you can play music continuously for 10 hours. If you turn off the stereo without disconnecting the wires, the stereo can standby for 270 days without depleting your motorcycle's battery.

**Q: Can you hear it over the motorcycle**
A: Not at high speeds or if your bike is noisy.

**Q: Can you sync and use 2 of these speakers together?**
