California Proposition 65 Warning

Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, is a California law that requires businesses to notify Californians about significant amounts of chemicals in the products they purchase, in their homes or workplaces, or that are released into the environment.

The law requires the State of California to maintain and publish a list of chemicals known to cause cancer, birth defects, or other reproductive harm. This list, which must be updated at least once a year, has grown to include over 900 chemicals since it was first published in 1987.

Important: The presence of a Proposition 65 warning does not necessarily mean a product is unsafe. Many everyday items, including foods, contain trace amounts of listed chemicals. The warning is intended to inform consumers so they can make their own purchasing decisions.

Car audio electronics, like many consumer electronics products, may contain trace amounts of chemicals that are on the Proposition 65 list. The most common chemicals found in audio equipment include:

The following Skar Audio product categories may contain chemicals listed under Proposition 65:

• Subwoofers - Electronics, magnets, and adhesives
• Amplifiers - Circuit boards with lead solder, plastic housings
• Speakers (Coaxial, Component, Marine) - Electronics, magnets, and coatings
• Tweeters - Electronic components
• Batteries - Lead acid batteries contain lead and lead compounds
• Amplifier Wiring Kits - PVC wire coatings may contain phthalates
• RCA Cables and Speaker Wire - PVC insulation and lead in connectors
• Sound Deadening Materials - Adhesives and plasticizers
• Subwoofer Enclosures - May contain treated wood, adhesives, and carpet materials
• Terminals and Connectors - Lead, brass, and nickel plating

Skar Audio, Inc. provides Proposition 65 warnings out of an abundance of caution. Due to steep penalties for non-compliance and because there is no penalty for providing an unnecessary warning, many companies (like Skar Audio) choose to provide the warning even when chemical levels may be below the thresholds that would legally require a warning.

It is nearly impossible to ascertain with 100% scientific certainty whether specific products require warnings, as manufacturing processes and component suppliers may vary. In lieu of testing each of our product SKUs and components individually, we have determined to comply with the law by labeling products with a Proposition 65 compliant warning.

The warning does not mean that our products will necessarily cause cancer, birth defects, or other reproductive harm. We believe our products, when used as designed and intended, are safe for consumer use.

To minimize potential exposure to listed chemicals when handling audio electronics products:

• Wash hands after handling products, especially batteries, terminals, and wiring
• Avoid prolonged skin contact with electronic components and circuit boards
• Work in well-ventilated areas when installing audio equipment
• Do not ingest any components or allow children to handle small parts
• Follow all installation instructions provided with products
• Dispose of products properly according to local regulations for electronic waste
