Re: ultra linear ul-600hc
If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following. I'll assume that you've checked the amplifier's on-board fuses.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp almost certainly has shorted output transistors and will need to be repaired.

Remove all the wires from the amp including the remote turn on wire. Once you do that, after about 30 seconds the amp will reset. Hook the power up first, then the ground then the remote. Turn the unit on and check for power WITHOUT the speakers hooked up. If you get no power by now it's a good chance that the amp is cooked. If you do get power, try hoking up your speakers first on one channel then the other channel and then bridged. If it cuts out or off when you touch the speaker wires to one channel or the other, then that channel is no good. Hope this helps.
Maybe, but you would need to take it to a stereo repair shop. If a wire is burned out or a small component is blown, it can potentially be replaced. May be cheap and easy, or may be too expensive to repair for the cost of the amp.
If you are getting power to the amp, try this....Find a small speaker, unhook your sub and wire speaker to amp. Turn on your system at a low volume....If the other speaker is playing through amp, then your sub is shot.....If the small speaker doesnt work, then its either your channel is gone on the amp or the rcas have quit off off your head unit.
try this get ur self a AA battery take ur stereo out of and get the two wires going to ur speakers that are not working and touch the battery with one wire on the positive and the other on the negative and see if u hear a poping from the speaker. and if u do thats the right wires and if u dont u need to find the right wires.( MAKE SURE UR STEREO IS NOT CONNECTED WHEN U R DOING THIS TEST. ALL SPEaKER WIRES NEED TO BE DISCONECTED WHEN PERFORMING TEST.)
and if u hear a pooping sound and it still dont work place the working speakers on the side thats not playing and if the dont play ur out puts are bad in the stereo and u need a new stereo. hope this helps
When I first got my Ka, the wiring between the car and the door was snapped. If you open the door there is a rubber tubing, if u assume 2 wires are snapped and try 2 pull them together through the rubber tubing you should hear a crackle if thats the fault. Even if you do not, it will almost certainly be this. To fix it, you need 2 use a stanley knife 2 cut open the rubber tubing then connect the to snapped wires together. I did this by getting a small amount of speaker cable and adding it 2 both ends, using plenty of insulation tape. This is the most common fault for speaker problems in the Ka.
i had the same problem check if any of your speakers are disconnected mine i was doing some work to it and i let the wire accidently touch a peice of metal and it would play for a bit then just stop playing music it is something to do with it heating and such

I often troubleshoot these issues via a stereo head set, modify the leads so you can "Touch" them onto the Speakers Output Terminals, connect the "Shields" together, thats "Earth" and the other Two, are Left & Right... with the Amp's volume turned to about 25% volume, connect up the Earth wires to the Chassis with a clip, under a srew etc, just make good contact... then touch the Left & right wires onto the output, ya should hear sound... if not most probably the Output device(s) may have gone faulty.
