Make sure you have a good ground from the amplifier to a metal surface in the car. Make sure this surface isn't paint covered and use a solid wire if possible (not stranded) to complete the ground.

Does the Hum pulsate?

Does the Hum get louder or softer when the ignition is turned?

Make sure your speker cables are not coiled or wraped up and or near any transformers, batteries, or other wires that have current running through them.

The most important thing is grounding.

Hifonics 1500D started to hum through subs after beating on them. Unhooked rca's and not the sound. Any ideas?


Check power supply diods. power supply capacitors and power supply and output transistors.
Remember, distortion is the biggest killer of subs and amps. Everything made by anybody has its limit.

My gale 3080 sub has a bad mains hum


Check that it properly grounded so that you don't have "ground loop hum" and that you have no power cords crossing other connections.

Hello beaugarcia26,

Unless the amp itself is defective, there's a short or ground somewhere.

First disconnect the speaker wires and RCA (or high level) inputs, leaving just ground, remote turn-on and power leads connected. Then see if the amp powers up normally. If it doesn't check the ground with a multimeter and make sure it is good. If the amp powers up normally, check the speaker, speaker wires and inputs for shorts or grounds.

Hope this helps.

Make the sub pop and hum and no rca wire are hooked in?


first off nice choice on the amp check ur power and ground connections make sure the main battery to bady ground is good if questionable add a new one cant hurt to have extra grounds from the batt to the body make sure the amp ground is as short as u can make it make sure its grounded to bare metal if any of these dont work u may have a prob inside ur amp

No sound in my Hifonics Brutus BXi 1206D amp


Have you confirmed that you have a good signal feeding the amp?

Have you confirmed that the speakers are in good working order and don't have any breaks in the wiring?
