Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Your amp is clipping.

The ground will not be the problem here as if it is grounded incorrectly the amp will NOT power up. Check the speaker cables to make sure there are no breaks. also check the rca cables for the same and make sure they are plugged in all the way. couldn't hurt to take a look at the remote wire. if you want to test the subs to make sure they are not blown try taking them out and hooking them to a home receiver you should be able to make sure they are carrying frequency that way. if so then check the head unit settings. Sometimes the wires inside the woofer box shake loose take one sub out and check if they are connected properly. Hope this helps.

No sound from subs


You need power to the amp. If the light on the amp is not on then your amp is the problem. Get power to it.

No power no sound


this may be because there is no signal going to the RMT terminal on the amplifier. try connecting a +12v line, this line tells the amp to turn on. it is normaly connected to the header unit of the car so that it will turn on the amp when the unit is powered on.

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.

Delay


10 to 20 minutes? that sounds like a internal problem in the amp. I have never heard of a amp taking that long to start up, there is definatly a problem in the pre amp stage of the amplifier.

Amp not putting out any sound


Check you pre amp RCAs and make sure they are holding a voltage...this is where the Amp takes that signal and amplifies it...without this connection the amp will not produce any power.

NEW AMPLIFIER WILL NOT LIGHT UP OR POWER UP


It sounds like your saying that you have two identical amp, that both are on the same power wires and remote wires and sam grounds? Well if thats the case then you did ok as One amp sounds like its blown. First tghing is check the main fuse. If its good and the unit still dosent resond then the power supply in the amp is blown as theres a switching supply that increases the 12 volts to get power to drive the Mosfet output devices. Was it ever working?? yes then the amp needs service. Do you know how to work on solid state elctronics down to componet level?? No?? Ok contact these folks at the addy im posting for you or take the amp to your local servicer. Good Luck. AudioSupport@VisonikCarAudio.com
