California Prop 65 Warning

What is Proposition 65?

Proposition 65 is a California law that applies to companies selling products in California. Proposition 65 requires warnings if a product contains any listed chemical present above very low levels. Proposition 65’s warning standards are among the most stringent in the world. Proposition 65 is not a product safety law, but rather a "right-to-know" law. Businesses are required to provide warnings to comply with Proposition 65.

There are over 800 chemicals on the Proposition 65 list, which is administered by California's Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency. The list includes naturally occurring and man-made chemicals. Proposition 65 warnings can be seen for a wide variety of everyday consumer products, including electronic equipment, and warnings can be seen posted throughout California in a variety of establishments such as buildings, hotels, restaurants, coffee shops, and stores.

Why do you see the warning on our packaging and website?

The warning is part of our ongoing effort to comply with the California Safe Drinking Water and Toxic Enforcement Act of 1986 (known as "Proposition 65").

boss MCBK420B

Everything I was looking for in a radio for my 2019 HD Heritage Classic. Easy to mount, and easy to connect. sounds great for the price too. the only complaint I have is the sounds it makes when it is turning on ! it makes 2 loud beeps to let you know it is connected I guess ? I wish there were some way to silence that ! GREAT BANG FOR THE BUCK !!

Great system for my Kawasaki Mule

I installed the Boss MCBK420B audio speaker system in my 2019 Kawasaki Mule SX XC. I chose this system for several reasons. #1 Boss sound systems have a reputation for good sound quality, value for money and durability . #2. I wanted a system with a minimal amp draw and at 4 amps it was just right (My Kawasaki Mule , like motorcycles, has a battery and charging system that are not designed for excessive amp draw). #3. Overall size and Bluetooth capability. I installed the amp inside my glove box. I dash mounted the volume control and a on/off toggle switch. The speakers clamped to a round frame under the dash but face the occupants from under the dash. In addition to the amp power being on a relay switched power circuit per instructions I also added the a fore mentioned dash mounted on/off toggle switch so I could manually switch off the amp when not needed to minimize amp drain. The sound quality is very good for the size of the system . Bass is a little lacking but then again I personally just wanted music , not bone shaking bass and enough volume to scare the animals. Don't get me wrong ,it will turn up loud, but not obnoxious. It is just what I wanted and it fit my Mule very nicely. Great Bang for my Buck.

Boss mcbk420b

Just wanted to comment on this product and also the 1000 watt 4 speaker bluetooth system that boss offers. 2 years ago I bought the 4 speaker 1000 watt system for my motorbike and its been nothing but incredible. Haven't had any issues and im happy with the product. I did see a comment where someone said the chrome wore off the speakers but that has not been my experience. I do store my bike after ever trip so it is not subject to the elements. So recently I decided to buy the 2 speaker boss 600 watt for my atv and same thing applies. This product is incredible and I highly recommend it. The price is just another bonus

Works Great on a RZR or Side by Side

Great overall clear sound. My only ask is they gave you more mounting options than just primarily for motorcycles (minus one star), but for the value these speakers are great. I mounted them to my 2015 Polaris RZR4 900, but had to buy additional 1.75" rollbar flag mounts to hold them since they come with only one size "handlebar" mounts. These things get pretty loud and have a overall clear sound. If you are looking for a lot of bass, then you may want to try some wakeboarding/marine style speakers; however, you wont get those for the same price as these.

AMAZING!!!

I installed this on my 14 Fatboy lo, plasti dipped the speakers black to match the bike, look great now but chrome wasn't that bad looking either. I put a fork bag on my bike to fit the amp and extra wire's in, wire's wasn't long enough to put in my saddle bags, this actually worked out much easier seeing I didn't have to run any wire's under the gas tank. I only had to run the negative & positive under my console to under my seat and connect the position to the ignition source brake light circuit then the negative to a bolt on the frame. I used 2 zip ties for the volume knob mounted it on my handlebar, everything looks clean and professional. Comes with everything I needed to set up this speaker system up and the Bluetooth works really well too! I can't stress enough how great these speakers sound!! I have a loud exhaust and with the volume all the way up I can't even hear the exhaust haha nice crisp and clear! If you're on the fence about buying it trust me, I...

Boss Audio MC400 Motorcycle audio speaker/stereo system

Received my Boss MC400 system very quickly. Ordered on October 27th, received from UPS on October 30th.

The Background: I use an iPhone 4S as my main audio source (iPod library, Pandora, TUNEin Radio). I have it paired with a Motorola S705 SoundPilot Bluetooth receiver.
