It probably has shorted output transistors. Read through the following page to eliminate other possible causes. Let me know if you have any other questions.

Power light flashing


This means it is blown. Whenever the power light flashes on any amp it is blown or something else is wrong with it. Most likely its blown. You can blow am amp by hooking it up to a powerful sub and blaring it, or just overheating it. Hope this helps. This can usually be fixed as well

HOW MANY LIGHTED HOUSES CAN BE HOOKED UP TO A BACHMANN CONTROLLER


You don't have enough power with a single controller to provide enough power to light all your light houses. You need to figure out the power draw & get a separate power supply.

I just bought a hifonics amp the brz2100.1D and when i tryed to hook it up every thing is correct as far as the wireing compared to the manual and the blue lights come on power light is on but its not...


MAKE SURE YOUR GROUND WIRE IS GROUNDED GOOD,,AND IT IS IMPORTENT TO HAVE YOUR REMOTE WIRE HOOKED UP. IT WILL BE A BLUE WIRE,,FIND THE HOT WIRE FOR YOUR TAIL LIGHTS AND HOOK IT THERE THEN WHEN YOU TURN YOUR CAR ON THE AMP WILL ALSO COME ON.THAT SHOULD STOP ALL THE NOISE AND POWER YOU UP.

Um the power light will flash then the protl. light will flash its all hooked up right but weird sounds coming out my subs.


Disconnect subs from output of amplifier and then turn on car and radio. Does amp stay on or go into protect? If it stays on then there is something wrong with the subs or how they are wired (series, parallel ) to the box and amp. If it still goes into protect then something internal with amp.

I have a pioneer gm-d8400m the amp isnt working


flashing light could mean a few different things. 1- constant power may not be there. check with a test light or multimeter. should read around 12 volts. it would be a good idea to check all the power and ground leads. make sure u have a good ground. 2- bad sub. im assuming sub since its a monoblock amp. you can meter the subs. make sure the total ohm load is no less than 2 ohms. any lower the amp will go into protect mode. 3- bad amp. power supply may be bad. the newer pioneer amps are full of protection circuits. ive been a professional installer for a shop about 8 years and we sell pioneer. hope it helps.

I miss placed my manual for my incredible holiday light show, The trees are all pluged in I get a flashing red light in the back but it wont start what am I forgetting to do


Just put mine up & it did the same thing. Unplug power. Have remote handy & paperclip. Find reset hole behind remote. Plug in power, red light will flash, hold reset button in until unit stops flashing. Make sure remote is also powered on. Thats it.
