## Questions & Answers

**Q: How does it wire into the bike?**
A: There is a power and ground wire that are attached to the bikes battery and a orange that is tapped in to a keyed power source. Sincerely, Greg

**Q: Can you run extra speakers off of it?**
A: LMFAO yes their math is ok crack 300 watt peak yet max is 4X23 yeah not even 100. Can someone from the company EXPLAIN?!?!

**Q: I have a 2007 V-Star 1300 and the keyhole is behind the handle bars...will this mount high enough for my hand to put key in?**
A: It may be able to be adjusted once it on your bars. I wanted my speaker to sit low facing me bc my Honda Fury bars a low and sleek but when I set it up I noticed has the gas tank key hole right on the top of the tank in the way. I was about to adjust the speaker in a way to still get the key in and out and get the tank cap off when the handle bars and turned so maybe you can see if yours can be maneuverd how you want it as well.

**Q: Can you hook up a sub woofer with this sound bar**
A: Yes

## Customer Reviews

### ⭐ Product not working
*by  on Reviewed in the United Arab Emirates 7 May 2021*

When connecting to a power source, it flashes once and goes dead.

### ⭐⭐⭐⭐⭐ Value for money. Hope it last for a 1yr or more.
*by  on Reviewed in Singapore 10 February 2021*

Loud. Worth money. Hope it last. Add another pair of speaker I am sure it will blast at traffic

### ⭐⭐⭐⭐⭐ This Speaker is Phenomenal
*by  on Reviewed in the United States 17 April 2021*

I’ve been wanting this speaker for months and I couldn’t pull the trigger because it’s pretty pricey, and what if you spend all that money and spend time on installation only to find out it doesn’t sound that good or you can’t hear it after hitting a certain speed like some other buyers have mentioned? Well, I finally decided to do it after the weather finally broke and I have zero buyer’s remorse. The speaker sounds absolutely awesome. Installation took about two hours, but that’s only because it took time to research things about my bike and figure out how to best run the wiring; if I had to install this speaker again, it would probably take 30-45 minutes give or take.Once it was on, it was as simple as activating Bluetooth on my phone. The speaker immediately connected, and I was playing music in less than 10 seconds. No issues whatsoever.Others have reported not being able to hear their music over 45-50 miles per hour, which was really my biggest concern. My bike is a 2021 Indian Scout Bobber, 1200cc’s with a Vance & Hines Twin-Slash exhaust. Simply put, it’s loud. There is no wind protection at all. I’ve ridden at 85mph since installing the speaker and I can tell you that I can not only still hear music but I can identify the song, it’s not just noise. Granted, at that speed it doesn’t sound great, but I don’t ever ride at those speeds anyway. At 45-50, it’s clear as day with full face shield helmet on.Being able to listen to my music on the bike has definitely added another level of enjoyment to my riding experience. You won’t be disappointed if you invest in this speaker for your motorcycle.
