Check your speakers with an ohm meter. They should have some resistance but not totally shorted. Its prob the amp that got fried. Connect the amp to the battery with no speakers attached to it if the protection light still comes on then the amp is blown.

If the amp is blown you can send it to people on ebay and get it fixed pretty cheap. Good luck!

Hey i dont know to much about amps, but me and my friend (he knows a decent amount about amps) would plug the power into the amp and the green light would come on. Though when we plug it into the subs, the...


Are you connecting positive to positive and negative to negative from the sub to the amp? If so, try positive to positve (+) in the far left channel and then the negative to negative (-) on the far left channel to. If no luck do the same in the other channel with one sub at a time. Try one sub at a time, Dont try an connect 2 or more subs to one channel as this would cause the amp to go into protect mode (red light you describe). Usually the positive wire has either a line down the wire, writting on it or has a red seperate wire with it when wire end stripped to connect it. Hope this helps and please rate...

Why is the red light that says protect on? my amp turns on but it dosent work, i have a sup hooked up & it dosent work. the red light that says protect is on.


first thing check all ground and power wires and make sure ur rca wire make sure it isnt cut in anyway. after that unplug ur sub and unplug the negative wire from ur amp, while its out check the fuses on the amp if all is well put all fuses back if not get new. then plug the negative wire back in if protect goes off check for heat and if no heat inspect the wires from speaker out put all the way to the sub, look for any wire touching another this is were most problems are even the smallest wire can trip a protect. if u still cant find the problem. an amplifier specialist is in order.if its trashed go on ebay and buy a powerbass there goin cheap right now. hope i could help

KAC9103d been running great for a year, factory refurb. for a month been losing sub output. checked all connections again, everything good. Turned on went driving 15 minutes later lost bass ckd again red...


Could be that you have a partially roasted(blown) coil on one of your subs which will function- but will keep tripping your amp.You can check that out just by using a different set of subs to listen to and by the process of elimination if the problem goes away then you know where the problem is at.Also check your gains you might be riding the gain a little high which causes distortion which causes heat(FAST) which will cause the amp to shut down completely or some amps will decrease output in a programmed attempt to save itself.turn the bass boost down to half if you even use it at all- that too can cause massive distortion in the amp itself,meaning only that if you have the bass boost on your deck turned up and then you turn the boost up on your amp the sound signal is then WAYYY distorted which will cause a thermal shutdown too. Last thing is to make sure that your subs arent running below 2 ohms because i believe that particular amp is designed to put out about 900 watts at 2 ohms.good luck

How do I hook up one sub to my rockford fosgate p3001 amp


Hey i have looked over many rockford manuals,(i own a 300.1 my buddy owns a 325.1) and for there mono(.1) amps there hooked together on the inside so channel A+ and B + are cencted on the inside the amp. So you ither hook one 2ohm sub to channel A or you can hook 1 4ohm subs to channel A and 1 4ohm sub to channel B. There 2ohm stable so any lower will eventualy burn the amp out.

I have kikcer amp 1500.1 is workin good for one year whith 4 memphis 15'' and one day just goin in the protection mode when i turn the radio up can you help me please


sounds like your amplifier does not have the power that your subs need check the rms out put on your amplifier and check how much rms your subs can handle if your amplifier has less rms power then your subs theirs probaly your problem that what happens when it kicks in to protection you could in up fring your out put chips in your amplifier not trying to say that the problem but check your rms power make sure the amp and subs can handle the same power

Have you checked the on-board fuses?

Did you confirm (with a multimeter) that you have voltage on the B+ and remote terminals of the amplifier?

Did you have the black meter lead on the ground terminal of the amp when you checked the voltage?

Protection light keeps coming on


Check the wiring between the sub and the amplifier. That's seems to be the only thing left that could cause a problem. If it's shorted to ground or pinched so the conductors are shorted together, it could cause the symptoms you listed.
