Frequently Asked Questions

Why is my amp humming?

Why, it must not know the words. (Gosh, I never tire of that one.) “Hum” and “whine” can be symptoms of improper grounding or crossed cables. Make sure your audio and power cables are separated from each other. Make sure you have grounded the amp properly. Good ground is close to the amp, and direct to the metal chassis of the car. Use the same gauge wire you use for your power cable, remove any paint at the ground point for a clean metal to metal contact, and use a “star” washer to get the best grip on the ground connection.
