B2 Audio USA Warranty Policy

1. Warranty Coverage

B2 Audio products are backed by a 1-Year Limited Warranty against defects in materials and workmanship under normal use. This warranty applies only to products purchased directly from B2AudioUSA.com or from an authorized B2 Audio USA dealer.

This warranty does not cover damage caused by:

• Improper installation, abuse, or misuse
• Operation beyond the product’s rated specifications, including clipping or overpowering
• Burned voice coils, seized voice coils, or other thermal failure
• Exposure to moisture, excessive heat, ultraviolet light, or other environmental factors
• Shipping damage caused by inadequate or improper packaging
• Products with altered, removed, or defaced serial numbers
• Unauthorized modifications, disassembly, or previous repairs
• Swollen, leaking, or physically damaged batteries. These conditions generally result from factors outside manufacturing defects, including overcharging, improper charging settings, excessive heat, physical impact, incorrect installation, misuse, abuse, or other external causes. Batteries showing swelling, leakage, cracked casings, punctures, or other physical damage are ineligible for warranty replacement. Immediately discontinue use of any battery exhibiting these conditions and follow all applicable safety and disposal guidelines.

A product that is not working does not automatically have a manufacturing defect. Products submitted for warranty consideration must be inspected and tested before a final warranty determination can be made.

2. Warranty Period

• All new B2 Audio amplifiers, subwoofers, speakers, and processors carry a 1-year limited warranty from the original purchase date.
• Refurbished, B-Stock, or discontinued products sold as clearance carry a 90-day warranty unless otherwise stated.
• The warranty is non-transferable and applies only to the original purchaser with valid proof of purchase.

3. Warranty Claim Process

7. Warranty vs. Non-Warranty Damage: Subwoofers

A manufacturer’s warranty generally covers verified defects in materials or workmanship. It does not automatically cover every type of subwoofer failure. The complete subwoofer must be inspected before a warranty determination can be made.

Damage That May Qualify for Warranty

Examples of issues that may potentially qualify as manufacturing defects include:

• Improperly bonded components
• Certain premature adhesive failures
• Manufacturing-related lead failures
• Factory assembly defects
• Other verified defects in materials or workmanship

Damage Generally Not Covered Under Warranty

• Burned voice coils or excessive thermal damage
• Damage caused by amplifier clipping, excessive power, or improper power
• Mechanical over-excursion or bottoming out
• Torn or damaged suspension caused by excessive movement
• Incorrect impedance or voice-coil wiring
• Improper amplifier gain, bass boost, crossover, or other settings
• Incorrect enclosure size, tuning, or design
• Improper installation
• Physical or accidental damage
• Water or moisture damage
• Unauthorized modification or previous repair

Important: A damaged voice coil does not, by itself, establish whether a failure is or is not a warranty issue. The complete subwoofer must be inspected to determine the likely cause of failure. Final coverage remains subject to the applicable warranty terms.

8. Out-of-Warranty Repairs for Non-Amplifier Products

Products such as subwoofers, speakers, and processors that are outside the warranty period may be eligible for customer-paid repair or replacement options. Please contact B2 Audio USA for available solutions.

Products repaired by B2 Audio USA carry a 30-day service warranty covering the completed repair.

9. Amplifier Repairs: In-Warranty and Out-of-Warranty

All amplifier repairs must follow the B2 Audio USA RMA process. Customers must submit the official RMA form and receive approval before sending an amplifier for service.

If you purchased an extended warranty through CPS, notify us when submitting your RMA request.

Amplifiers shipped without an approved RMA may be refused or returned to the sender at the customer’s expense.

Approved Shipping Instructions

Do not ship an amplifier before your RMA request has been reviewed and approved.

• After the RMA request has been reviewed and approved, B2 Audio USA will provide the correct shipping address and instructions.
• Repair locations may vary depending on the amplifier model and type of service required.
• The customer is responsible for shipping the amplifier to the designated repair facility unless otherwise stated in writing.
• The amplifier must be securely packaged to prevent shipping damage.
• The approved RMA number must be clearly marked on the outside of the package.

Amplifiers shipped before RMA approval, shipped to an unauthorized address, or shipped without the required RMA information may be refused or returned to the sender at the customer’s expense.

Diagnosis Timeline

• Please allow up to 5 business days after receipt of the amplifier for diagnosis.
• This period covers the initial evaluation and determination of whether the amplifier is repairable. It does not include repair time.

In-Warranty Amplifier Repairs

• If the amplifier failed because of a covered defect during normal use within the 1-year warranty period and is repairable, B2 Audio USA will cover return shipping within the continental United States.
• If inspection determines that the amplifier was abused, misused, improperly installed, or otherwise excluded from warranty coverage, customer-paid repair may still be offered.

Out-of-Warranty Amplifier Repairs

• Amplifiers outside the 1-year warranty period may still be eligible for customer-paid repair.
• An $150 non-refundable diagnostic and bench fee applies. This fee covers the evaluation and must be paid before a repair quote is provided.
• After diagnosis, B2 Audio USA will provide a repair quote. The customer may choose to:
  • Proceed with the repair at the quoted cost;
  • Have the amplifier returned at the customer’s expense; or
  • Request disposal of the amplifier.
• If an amplifier is deemed unrepairable because of catastrophic board failure or other irreparable damage, the customer may have it returned at their expense or request disposal at no additional cost.

Repaired amplifiers carry a 30-day service warranty from the date the repair is completed.

10. Warranty vs. Non-Warranty Damage: Car Audio Amplifiers

A manufacturer’s warranty generally covers verified defects in materials or workmanship. It does not automatically cover every amplifier failure.

Every amplifier submitted for warranty consideration must be inspected and tested to determine the cause of failure. A non-working amplifier does not automatically have a manufacturing defect.

Damage That May Qualify for Warranty

Examples of issues that may potentially qualify as manufacturing defects include:

• Premature internal component failure under normal operating conditions
• Defective internal components
• Manufacturing-related solder-joint failure
• Factory assembly defects
• Internal component failure without evidence of abuse, excessive voltage, or improper installation
• Defective protection circuitry
• Manufacturing-related terminal or connection failure
• Other verified defects in materials or workmanship

Final warranty eligibility can only be determined after inspection and testing.

Damage Generally Not Covered Under Warranty

Low Voltage or an Insufficient Electrical System

Car audio amplifiers require adequate and stable electrical power. Damage caused by insufficient voltage or an inadequate electrical system is generally not considered a manufacturing defect.

Examples include:

• Excessive voltage drop during operation
• An undersized alternator or inadequate charging system
• Inadequate battery capacity
• Poor or undersized power and ground wiring
• Loose or high-resistance electrical connections
• Poor grounding locations

High-power amplifiers may require significant electrical-system upgrades to operate safely.

Excessive or High Voltage

Supplying voltage above the manufacturer’s specified operating range may damage the amplifier’s power supply and other internal circuitry. Damage caused by excessive charging voltage, improperly configured lithium systems, external power supplies, or other over-voltage conditions is generally not covered.

Reverse Polarity

Connecting positive power to ground or ground to positive can cause immediate and severe internal damage. Reverse-polarity damage is not considered a manufacturing defect.

Incorrect Speaker Impedance

Operating an amplifier below its rated minimum impedance can cause excessive current draw, overheating, protection problems, or internal component failure.

Examples include:

• Wiring a 1-ohm-stable amplifier below 1 ohm
• Incorrectly wiring multiple subwoofers
• Incorrect voice-coil wiring
• Using a speaker load outside the amplifier manufacturer’s specifications

Clipping or Improper Settings

Amplifier gain is not a volume control. Improper gain settings, excessive bass boost, incorrect signal voltage, sustained clipping, or improper crossover settings can create excessive heat and stress internal components.

Shorted Speaker Outputs

Speaker wires that touch each other, contact vehicle ground, or become pinched or damaged can create a short circuit at the amplifier’s output. Repeated or severe output shorts can damage the amplifier.

Improper Power or Ground Wiring

Installation-related damage may include:

• Undersized power or ground cable
• Poor-quality wiring
• Loose or corroded connections
• Improperly crimped terminals
• Excessively long or inadequate grounds
• Improper fuse installation
• Insufficient grounding

Water, Moisture, or Contamination

Amplifiers must be installed in a dry, protected location unless specifically designed for exposure to the elements. Damage caused by water, moisture, condensation, corrosion, dirt, debris, drinks, or other liquids is generally not covered.

Overheating or Improper Installation Location

Amplifiers require adequate ventilation. Installing an amplifier beneath carpeting, inside a compartment without sufficient airflow, against heat-producing equipment, or in another location that prevents proper cooling can cause thermal damage.

Physical Damage

Warranty coverage generally does not include:

• Broken RCA connectors
• Broken power or speaker terminals
• Stripped terminal screws
• Damaged knobs or switches
• Cracked or damaged circuit boards caused by impact
• Bent or damaged amplifier chassis
• Dropped amplifiers
• Vehicle accident damage
• Shipping damage unrelated to the original shipment

Modification or Unauthorized Repair

Opening, modifying, or attempting to repair an amplifier may affect or void warranty coverage.

Examples include:

• Modified circuit boards
• Replaced, added, or removed internal components
• Soldering performed by an unauthorized repair facility
• Modified protection circuitry
• Altered power or speaker terminals
• Missing, broken, or altered warranty seals

How We Determine the Cause of Failure

Our technicians may inspect the amplifier for evidence including:

• Burned or damaged MOSFETs
• Damaged power-supply components
• Burned output devices
• Overheated circuit boards
• Melted or damaged terminals
• Signs of reverse polarity
• Excessive-current damage
• Over-voltage damage
• Speaker-output shorts
• Corrosion or moisture
• Physical damage
• Previous repairs or modifications

The location, type, and pattern of component damage can help determine the likely cause of amplifier failure.

Important: An amplifier entering protection, producing no output, blowing fuses, or completely failing does not automatically indicate a manufacturing defect.

If inspection determines that the failure resulted from a covered defect in materials or workmanship, the amplifier will be handled according to this warranty. If the damage resulted from installation, electrical-system problems, improper impedance, excessive or insufficient voltage, misuse, physical damage, moisture, modification, or another excluded condition, the claim will be denied or the amplifier may be handled as a customer-paid repair when available.
