In the event that an Ampere Audio Amplifier/Subwoofer fails due to a manufacturing defect, we will fix or replace it free of charge for a time period of one year from the date of purchase. This only applies to the original purchaser with original box and accessories must accompany. Warranties are non-transferable and amplifiers will not be covered under warranty if ran below a 1 ohm load or if underpowered by a weak electrical system. Failure to do so can decrease the life of the amplifier and void your warranty.

This warranty does not apply with respect to the following:

  1. Ampere Audio’s warranty does not cover burned/open voice coils or lead wires, ripped surrounds or folded cones.
  2. Defects or damage caused by environmental accidents.
  3. Products that have the serial numbers removed or altered.
  4. Products which have been altered or repaired by anyone other than Ampere Audio or dB-r.

All returns must be sent with a RA # on the outside of the box in four place. Products sent without a RA will be refused and shipped back at the customers expense. The RA # can be obtained by contacting Ampere Audio and requesting the needed information.

Warranty claims must be accompanied by the original invoice to validate the warranty service or contact Ampere Audio for information.
