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.

My subwoofers will make no sound now


Go through the multiple menus of your head unit, and make sure the subwoofer setting is set to "yes".

Do you have the owner's manual for the unit? What make/model is the head unit?

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 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
