What is your warranty policy?Updated 24 days ago

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 a manufacturing defect 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, bottoming out, or torn/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 manufacturer's warranty.

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 a manufacturing defect 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 determination can only be made after inspection and testing.

Damage generally not covered under warranty

Low voltage or an insufficient electrical system: Excessive voltage drop, inadequate alternator or battery capacity, undersized power/ground wire, poor grounding, loose connections, or other high-resistance connections can damage an amplifier. High-power amplifiers may require significant electrical-system upgrades.

Excessive or high voltage: Voltage above the manufacturer's specified operating range may damage the power supply and other circuitry. This includes damage caused by excessive charging voltage, improperly configured lithium systems, external power supplies, or other over-voltage conditions.

Reverse polarity: Connecting positive power to ground or ground to positive can cause immediate and severe internal damage.

Incorrect speaker impedance: Operating an amplifier below its rated minimum impedance can cause excessive current draw, overheating, protection issues, or internal failure. This includes incorrect subwoofer or voice-coil wiring and any speaker load outside the manufacturer's specifications.

Clipping or improper settings: Amplifier gain is not a volume control. Improper gain, 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 an output short and damage the amplifier.

Improper power or ground wiring: This includes undersized or poor-quality wire, loose or corroded connections, improperly crimped terminals, excessively long or inadequate grounds, improper fuse installation, and insufficient grounding.

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

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

Physical damage: Warranty coverage generally does not include broken RCA connectors, broken terminals, stripped terminal screws, damaged knobs or switches, impact-damaged circuit boards, bent chassis, dropped units, vehicle accident damage, or shipping damage unrelated to the original shipment.

Modification or unauthorized repair: Opening, modifying, or attempting to repair an amplifier may affect or void coverage under the manufacturer's policy. This includes modified circuit boards or protection circuits, replaced/added/removed components, unauthorized soldering, and altered power or speaker terminals.

How we determine the cause of failure

Our technicians may inspect for burned or damaged MOSFETs, damaged power-supply components, burned output devices, overheated circuit boards, melted terminals, reverse-polarity evidence, excessive-current or over-voltage damage, speaker-output shorts, corrosion, moisture, physical damage, broken warranty seals, previous repairs, or modifications. The location, type, and pattern of damage can help determine the likely cause of failure.

Important: An amplifier going into protection, producing no output, blowing fuses, or completely failing does not automatically indicate a manufacturing defect. If inspection confirms a covered defect, the amplifier will be handled according to the applicable manufacturer's warranty. If the failure 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 unit may be handled as a customer-paid repair where available.
