No problem i see. Should be the power light, and the lower the ohms the better it is.

Low ohm light flashes but green light also on

It might be an issue with the crossover network. A high pass cap may be shorting intermittently. You may also have a loose wire abraiding somewhere.

Subwoofer quit being as punchy, went to check the wires toched the amp it was blazing hot, then the green light went to red, what are we doing wrong?

Most often it's a thermal overload, which is most often due to an impedance (ohm-load) that's too low. Check your speaker configuration against the minimum impedance your amplifier can handle.

My 79 honda500 want fire i know the coils are and plugs and plug wires are good what else could it be and it hasnt jumptime either

have you checked the spark plug caps, if they read above or below 5000 ohms replace them. If they are good then the news is bad. You could have a bad cdi box but more likely with this model , you have bad pulsar pick ups, which unfortunately are part of the alternator assembly. These can be checked without removing the engine by taking readings from the plug going to the cdi box. ac generator disconnect the stator wires at their connections. X10omega
white-blue 77-95 ohms
green-white 387-473 ohms
orange-green 95-116 ohms
light blue-green 95-116 ohms

light blue/red-green 81-99 ohms

My visonik v700hc keeps going into protect modeafter listening for a couple minuits then will go green light then back to red after a coupke more any solutions

I suggest checking what ohm load you're presenting to that amp. go to and find the subwoofer wiring diagram and choosing the amount of subs you have on it and then the impedence of each one. you're probably sending too low of an ohm load to the amp this would cause it to go into protection quite frequently and eventually stay in protection.

Jl audio 300/4 low ohms light wont go off

If the low ohms light is on then you have your speakers wired to low. I need to know some more info like what type of speakers you have running on this amp and how many. Also was it working before and then it started doing this? Check the ohms with a volt meter if you know how, if not just get a volt/ohm meter and set it to the ohms setting and then take the positive(red probe) and touch it to the positive terminal on the speaker and then the negative(black probe) to the negative terminal and see what it reads. Make sure you check how low in ohms your amp is capable of handling. If you don't know just google the model of your amp and you will find a site that has a manual or just go to JL audios web site and you should find out there with no problem. Let me know what you find so I can assist you more if need be cause I also repair amplifires for a living and have many years experienc and I'm the cheapest amp repair business you will find any where. Good luck

I have 1000 watt sony XPLOD amp and i just installed it today. with new monster cable&ground. the green light turns on& thumping goes for a little. i try to raise up just a little bit& after 2...

it isnt getting enough power and its tripping the internal switch on the amp and putting it in safe mode. either your wire isnt a high enough gauge. you might need a capacitor or you need bigger wire.

500/1- Low ohm light

Disconnect the speaker wires from the amplifier's terminal block. If the low ohm light still comes on with no speaker wires connected, the amplifier will need to be repaired.

If the light no longer comes on, check the speakers and the wiring.

Check engine light

one possible cause: many cars use the engine coolant temperature sensor to control idle speed and to shut down a dangerously overheated engine. if this sensor is sending a false signal, the controller will not know that and it will continue to listen to it. your task is to try and see if this signal is true or false. do this by measuring (USING A HAND-HELD MULTIMETER SET TO LOW OHMS RESISTANCE TEST) the resistance change across this sensor identified by a blue/white or yellow/red wire at one connector and a brown/green wire at the other connector. the sensor is located near the thermostat on the hot side of the coolant outlet from engine. if you find no change in ohms or find infinity ohms or always zero ohms, change the sensor and the light may fix itslef over time.

Low ohm light on with now RCA's or speaker wires attached? What is going on???? Sound is crap it was working fine for the last year ????????

ohms are impedance or the amount of current being blocked through the line. The lower the ohms the less resistance. Speakers run at a certain ohm (or at least are recommended to run at). Have you bridged your amp? Usually when you bridge your amp it lowers the ohms by half. You may have damaged something, especially if you bridged your amp and didn't bridge it properly.

The red light on my amp keeps coming on and it wont work

You need to check your woofers. Most likely one or both may be a) blown or at a dead short or b) the ohm rating on them may be too low. What model woofers and amp do you have??
