Hifonics woes!

Helloooo,

I drove to the store today and my sub/amp was workin fine, but when I got out and turned my system on again the bass knob blinked RED and then went out.

The Amp appears to be getting power, as the blue hifonics isignia is lit up as usual. would it still turn on is fuses were blown? the PROTECT light is not lit.

ANY insight would be greatly appreciated, thanks!

If the fuse is blown there should be no power at all in the amp.

Disconnect the sub and hook an old crappy speaker to the terminal and see if you can get any output, you don't need to crank the amp way up and blow the speaker this is just to see if there is any output from the amp.

If you do get some output from the amp then turn to your sub, the voice coil could be damaged or a speaker connection in the box may have came loose.

weird, same thing happened to me. but the hifonics blue/red logo on my bass knob never went back on ever since i touched it with a shock. you know that shock you get/give when you touch certain things...yeah, did that to my bass knob and the bass knob light went out but everything still worked perfectly fine (including the amp)

Static electricity shocks are surprisingly high voltage. To even feel a static shock it needs to be a minimum of 3500 to 4000 volts and can go as high as 12000 volts, these voltages sound incredible but you must remember that the amperage is minuscule and pose no threat to our safety.

The LED light and its resistor in your bass knob is extremely sensitive to voltage and was damaged as the current traveled from your finger tip and into the knob.

is it possible to "fix" and make the light go back on my bass knob when powered on, again?

another unusual thing was i seen the blue light and even red light go on randomly like when i turn on the ignition but suddenly go off.

Replace the LED with?

If it is easy to remove I'd imagine it would simply be a matter of replacing it with one of the same value and re-soldering it in place.

But don't quote me on that....

just make sure that u wire it up the same as how it was when u took it out, if u wire it wrong u could blow that LED too...cathode side goes to neg. side iirc.
