I have an MTX audio JH 300 amplifier. When I turn the power off from the amp the yellow light comes on and stays on continuously. after about 15 minutes listening music amp shuts off, why


the light stays on because the amp is still storing power. it only turns off when the capacitors on the inside have drained off all the extra power

My brake light on my dash is constantly on


Look beneath the dash panel at brake pedal assembly. You should see the brake light switch, which completes a circuit to brake lights when you step on the brake pedal. Its likely this switch is malfunctioning. The circuit is closed (power to brake lights) when the brake pedal is not depressed. The circuit is suppose to be open (no power to brake lights) when your foot is off the brake pedal. Unplug the wire connector and unscrew to replace this brake light switch.

As for the knocking sound, is it when the vehicle is in motion? Or even when the vehicle is stopped and idling in park?07060338-db0d-4c14-8a08-ace846c99fb4.jpg

Not a green light comes on like normally... a yellow one comes oh


could be the wires is bad or someplace the power wire is grounding out or the fuse or fuses is blown. or could be not enough voltage but highly doubt it.

MTX thunder 304 4ch red amp light comes on but no audio have triple checked all connections and they seem alright


if the lights on and there is no sound it's either a cd player issue or your rca issue or the inputs for rca's on the amp are no good. or you have your subs wired at a wrong load to your amp and it is in a constant protection to avoid burning up.

No LED power lights go on


the light with the power light(middle) is a blue/purple faint light try checking it out at night.The squiggy(as heat waves) will only light when the amps shuts down due to thermal protection(wait for it to cool). The bolt/yellow (short circuit) will light when there is an electrical overload in any of the wires(check +ve leads).

If the terminals were smoking, it's probably due to loose screws in the terminal block or wire that's too small.

Did the amp work properly after the terminal blocks smoked?

Amp works fine i think??? but Prsim efx not working at all


You need to contact MTX tech support before the warranty runs out. You'll probably have to get an RA number to send it back.
