Power on/off i have this amp hooked up to a 12" fosgate. it has been going good for a year now untill the other day. when i turn on the car, the blue light will come on and then quickly power off. I checked the grounds, the power, and the on/off wire, also their are no blown fuses. what could be the problem?

Solidus- Your amp is going into protection mode, try disconnecting the sub and see if the power will stay on then.If yhe power stays on,it is your sub-blown or shorted ect. But if it does the same as before,its to the repair shop. cooltek Mar,4/08

I have two 12 rockford fosgates p3 hooked up to and 350.2 kicker amp i just got them so i hooked them up and my amp will keep turning on and off


How may ohms are the p3's and how are they hooked up? Some amps won't handle less than 4 ohms bridged. Try running one sub to each amp channel.
Also check power and ground connections.
Useing too small of wire for power, ground can cause the same problem.

Wont turn on. everything should be connected properly, got new fuses to make sure. It worked fine until i dismounted and disconnected it from the battery. When i reconnected it, no luck it is a Autotek...


Make sure this high powered amp is not mounted directly to the chassis of the car. Mount it to a wooden board and you can screw board into the car. Because some very high powered amps can arc and damage itself.

Next make sure the tubular fuse in the hood is not bad it may look good but internally it got real hot and caused a bad solder connect in the fuse. You can test it with a meter. Measure one side then the other side if the 12 volt is going thru the fuse.

Next step is now you know your amp is getting 12 volts from the car battery but do you know if your amp turn on signal is turning on the amp itself. This is a easy test get a little wire and jump the 12 volt to the amp turn on wire if the amp comes on then you have found your problem. The amp turn on voltage is too weak were ever youve connected the signal. Normally you hook it up to the blue/white wire on the back of the radio first. If it doesnt have one hook up to the blue. Now on some very rare occassions the voltage drops when you put a load to it and is not enough to turn on your amp you can easily see this if the voltage across the blue wire goes below 12volts so hook it up to the red ignition wire so at least when you turn on your radio the red will send 12 volts to the amp to turn it on and will not drop in voltage. You see that wire has to be 12volts when it drops the amp will not turn on. Same with the battery Voltage you have to maintain 12 Volts or higher for the amp to operate.

Amp fuses blowing and amp overheat


Does the amp heat up if you power it up with no speaker wires connected to the amplifier's speaker terminals?

Rockford fosgate punch 700s gets very hot


Disconnect the speaker wires from speaker terminals on the amp and turn the amp on (turn the head unit on). Set the volume to zero on the head unit.

Does the amp get hot?

If it does, either the bias is set to high or the amp has other problems. If it does not, you may have the speakers wired to the wrong ohm load.

My amp only powers the subwoofer when the radio is on but wont when the cd player is on


The person(s) who hooked up your system made a boo boo. They wired your remote turn on lead to the power antenna lead instead of the amp turn on line (both are blue and easy to mix up). Thus when your radio is on it sends a signal to the amp and the amp turns on, but when you set to CD the signal goes away and your amp shuts down. Easy fix, just re-wire the amp turn on lead and the problem will be fixed.

My amp turns on but once you turn the volume up it shuts off


What is happening is an overload situation. If you can use either left or right (white or red) RCA inputs but not both, then the amp is overloading and getting hot internally and probably getting ready to die. You'll need someone to fix the final drivers in the amp.
Hope this helps, and please rate my advice.
Thank you, and good luck!!

Remote wire hook up


The Remote wire should connect to the remote turn on lead from you radio(most aftermarket radios use a blue and white or a blue wire for the remote turn on). This wire will send a 12v signal to the amp from the radio when the radio is turned on. You can disconnect the remote turn on lead from the amp and jump a wire from the terminal marked battery to the remote turn on terminal just to see if the amp powers up. Do not leave it this way however because your amp will not shut off and your battery will go dead.

Punch 100a2 problem ouch


Without the proper training in electronics , Nowbodys goping to be abl to explain to you the way to trouble shoot something without you knowing the lingo and also what the terms mean and do!. You also need to know how to use a multimeter, an ocilliscope,have load resistors to hook up to the amp . A good power supply . You also will need to know how to read a resistor as the resistor color code. And Know how to test capacitors as well as a solid state device. im sorry i cant help you but I wish it was that easy to do or I wouldnt have went to school all these years. Send the unit into the factory or to a repair shop as you could cause more damage if you short something out by accident. Good Luck
