Identify your component
The gallery shows two different examples of individual single-channel amplifiers, not different viewing angles of one amplifier. Compare your component and contact M&R at 1-800-343-1382 if you are unsure. Appearance alone does not establish compatibility. Supported part numbers and vehicle applications must be confirmed before ordering if your component is uncertain.
Describe the problem
Tell us whether the affected speaker has no sound, intermittent or low audio, static, popping or squealing. These symptoms can have several causes and do not prove that the amplifier is faulty.

Warranty and turnaround
M&R’s published repair information states a full one-year repair warranty and says most repairs can be repaired and shipped back in as little as 3–5 business days. This is not a guaranteed completion date; contact M&R for component-specific timing. For completed repairs, review applicable return-shipping charges in checkout. If an amplifier cannot be repaired, M&R Electronics will refund the full $150 repair charge for that amplifier and return it to you at no charge.
