## Description

KSPEAKER KS-K2BL bluetooth waterproof sound system brings you enjoyable music.;The one-piece metal body and a pair of 3-inch full-range speakers can be installed on motorcycles, scooters or ATVs (fit round tube 7/8 Inch, 1 Inch, 1.25 Inch).;The Bluetooth function allows you to connect to a music device to play your favorite music, and you can use the FM radio function to accompany you with messages whenever you want.

Review: Motorcycle Audio Perfection - The power, clarity, volume, and design of this unit far exceeded my expectations. Pure quality. Installation was a breeze. You’ll hear the perfect combination of sound quality and volume rolling down the Interstate at 70 mph. HIGHLY recommend.
Review: This thing is phenomenal - It was an absolute pain to install onto my handlebars because the adjusters just could not stretch to the right angle for my bike. Nonetheless I eventually managed to get them on there. It is very sturdy, had great features, and best of all it’s LOUD! It comes with a flash drive already installed (that you can remove) that’s loaded with songs (a very mixed variety) , has Bluetooth, and plays the radio as well. The radio picks up stations but it’s the greatest at finding signals, I do with it had an antenna or something. But this thing is loud, I can hear it when I’m cruising on the highway doing about 70-75 just fine. I’m sure if you have one of those obnoxiously loud bikes it’ll be a lot harder to hear, but that’s the price you pay, you’d rather hear the bike than great music lol. I ride a 2024 Kawasaki Eliminator 450cc for reference. Love this thing, it kicks butt. UPDATE after like 8-9 months : 1. The radio feature is extremely limited to non functional. It basically doesn't pick up stations even with very strong signal. 2. You can technically hear it at highway speeds but you should probably use headphones or ear plugs at highway speed regardless to prevent yourself from getting hearing loss. It is super rainy though once you pass 65 mph. Non existent at 70 mph. I keep it on my bike to use it for when I'm parked somewhere or hanging out with people and we want to listen to music. It's great for when your at the lake or river and want to blast music while y'all swim or something. Would be nice to use as well on days you plan to just putt around town , not going over 50 mph , and just enjoying a little ride around. I realize my original review was a bit exaggerated and optimistic but I've come to straighten that out lol.

## Questions & Answers

**Q: will this work on 2005 harley softtail?**
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**
A: This is what we do very well, unlike other brands, our audio has a superb standby capability. Listen to music while the motorcycle is starting, you don't have to worry about draining the battery at all, as long as the motorcycle engine is running, the stereo will always have power. 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?**
A: No you cannot sync 2 of them together

### ⭐⭐⭐⭐ Bass weak, volume inadequate at higher speeds, overall a decent unit for the price and features.
*by D***S on July 10, 2025*

I read reviews prior to purchasing so was aware what to expect. Previous reviews were pretty accurate. Installation was not overly difficult. Unit is easy to operate. Bass is very weak but was expected. Volume is not adequate at higher speeds; fairly clear up to 50-60mpr, over that it is difficult to clearly hear. Softer music will be un-hearable at higher speeds. I installed on a Harley Softail with somewhat moderate exhaust sound level, with louder pipes as I have on my other bike this would probably not work at all at higher speeds. Bluetooth music is clearer than FM radio, assuming a better signal feed from Bluetooth. Overall a decent product for the money. Will work well around town or at moderate highway speeds. Did not want a unit with external controls (mostly bad reviews on those items), probably one of the better units available for the price range and features.
