Hi. Ive had this amp for about 3 months. which connects to my kenwood sub. the other day, the red light on the amp came on (protection mode) and i have no idea why, or how to fix it. I looked at it and the 12v cable was very loose, so i re-connected that and protection light is still on PLEASE help!!!

ok if the amp was in safe mode before the sub was hooked up then the amp needs to be fix , make shor the suds are hooked up right an the wires arent touching , the amp is in pro mode so there for u have to find out more on why the amp is not working or let me know what is goin on with it ,
Despite the fact that they claim that the amplifier is 500 watt RMS if you look at the fuse it has on it, which should be one 30Amp fuse it means that the max that you might get out of this amplifier is 300 watt RMS. So an 8 Gauge cable will be more than enough for it. However, saying that, using a 4 gauge cable will not harm it in any way. what you should check before buying a 4 gauge cable is if it will actually fit in the allocated 12V terminal.
The unit will need to be repaired by a technician. Most likely you have a bad transistor that is causing the protect mode to turn on. The only way to get the protect mode to turn off is to remove the bad part.
never ask geeksquad about amps lol check your ground wire connection and push on sub do you feel scratching if so its blown sub also never turn an amp up all the way it starts pushin dc voltage witch a 200 watt amp can blow a 800 watt sub dc voltage is not good for subs also up all the way can burn out the internal battery in the amp lets hope thats not it just make sure ground is good protection light means that the amp has power but a connection is not bien made sum where to complete the circut
i dnt knowwat type of speaks u got but ifits low then it cud be tht u have too open up the second coil on ur speakers...dnt sound like the amp since its on & not in protect mode,other than tht i'll recheck the wiring
The most common reason for an amp to go into or remain in protect mode is shorted output transistors. To eliminate other possible causes, read through the following page. Let me know if you have any other questions.
Unplug the inputs and outputs from the amp (be sure to mark the wires so you can hook them back up), leaving only the ground, +12, and remote wire hooked up. Now, turn it on. If the amp light goes red, the amp is broken. If it goes green, turn if off, plug in the speakers, then turn it on. if it's red, its a speaker problem, if green, do the same with the inputs, and you'll have your answer.
