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.

Let me know if you have any other questions.

Hello. I have an Ultra Linear Amp - UL724 model. I am wiring it up to play in 2 channel mode - in stereo. I can only get one channel to work - the left... I swap the rca cords, still only the left side...

YOUR METHOD OF TROUBLESHOOTING USING THE PROCESS OF ELIMINATION IS RIGHT ON AND PERFECT. IT INDICATES A BAD AMPLIFIER CHANNEL. I KNOW THIS SOUNDS ODD, AS YOU HAVE TWO OF THESE NOW. IT IS RARE, BUT I HAVE SEEN INPUT CONFIGURATION SWITCHES WIRED BACKWARDS, SO THE ONLY THING LEFT TO DO IS TO HOOK UP THE BAD CHANNEL TO ONE SPEAKER ONLY, BY ITSELF. THEN TAKE ONE RCA ONLY AND PLUG IT INTO ONE RCA INPUT AT A TIME. THEN MOVE THE INPUT SWITCHES AND REPEAT THIS PROCEDURE UNTIL YOU HAVE TRIED ALL SWITCH COMBINATIONS AND ALL INPUT JACKS. WHAT YOU ARE TRYING TO DO AT THIS POINT IS TO DETERMINE IF THERE IS ANY RCA JACK WITH ANY SWITCH POSITION, THAT WILL ALLOW YOU TO GET OUTPUT FROM THAT CHANNEL. IF AFTER THIS TEST, YOU STILL HAVE NO OUTPUT, THEN NO MATTER HOW ODD, IT WOULD INDICATE THAT YOU DO IN FACT HAVE A SECOND DEFECTIVE AMPLIFIER. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

I have a linear amp 1600 I ahve power to it but it wont work and what is the remote wire supose to be connected to?

The remote wire is supposed to be connected to the remote output on the back of the head unit that is feeding the amp.
Without the remote wire hook up the amp will not turn on.
Reason for this is, the Head Unit tells the AMP to turn on, without the remote connected the AMP is going to do nothing, find the remote switch wire on the back of your Head Unit and run the wire to the remote input on the AMP.

Ultra Linear UL600HC gain pot broken off of board

No, open the system, check the switch in questions, get a soldering iron and desolderer to remove the switch, do it carefully, when you have the switch in your hand go to maplins or somewhere like it, find an exact replacement(wont be hard to do) and get someone confident with a soldering iron to solder it back in.

IVA-D300 only LEFT speakers work.

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

It goes into protection mode

hi there
you will need to get a larger ground wire and it needs to be mounted to metal surface. this means you may have to scratch some paint in area where you will place the new ground wire (note do not add any other wires to this ground)
if that doesn't solve the problem than your settings may be to high on the amp but this sounds like a ground issue also make sure no fuses in amp are blown
hope this helps

Power light on the amp goes on after 5 sec off ultra linear 1200

If you run the remote from the battery you will need a on/off switch. Sounds like the amp is overheating. Also, I don't understand bridge the remote and power. They should be seperate going into the amp.

I have problem with my mono amplifier

Amplifiers have thermal protection. They will typically shut down at ~180F. If your amp is shutting down after running it hard for 20-30 minutes, you may not have the correct load impedance (speakers wired incorrectly).

If it overheats as soon as it's switched on (no audio), the amp may be in need of repair.
