I HAVE A PYRAMID PS-52KX I NEED TO KNOW THE R13 RESISTOR OHMS AN TOLARENCE AND WATT.

what type of resistor is it? are there any colored bands to signify the ohm rating?
thank you,
Lee

Hi, yes sure you can. Just be sure when disassembling to make notes where necessary to keep track of where parts go-and when you get to the lamps ( either under or in back of the meters-use a volt/ohm meter to measure to voltage so you know the size to replace them with ie.. a 6 volt or 12volt. be careful when powering on a disassembled unit ( no parts touching each other, touching a metal part of cabinet) and if you want you can wrap some electricians tape around loose or exposed parts for safety. Good luck, I hope this was of some help and thanks for choosing FixYa. Prodzilla

What exact model? Do you mean the "protection" indicator?

You might find some help or documentation here...

Generally speaking, an amp protects itself from heat, shorts and overloads.

Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure
the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without
addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

According to this listing I found on eBay it will work for you.

The pb180 has High Input receptacles on the back end. They are marked High Input and identified as Channels 1&2 left/right, and channels 3&4 left/right. You will need to identify all speaker wires coming from your head unit ( left front +&--) , and so on. You will be sending the speaker wires from the head unit to the pb180's High Inputs. In other words, the front left speaker wires(+&-) from the head unit will go to the High Input Channels 1&2 side, left input of the pb180, and so on, so the speaker wires coming out of the head unit will need to be cut. And LABEL all sets of speaker wires before you cut them! Then on the OUTPUT end of the pb180, you will be sending the wires back to the the respective speaker wires which are going to the speakers. So it's out from head unit to pb180 and out from pb180 to speakers.
Hopefully you have the plugs that Pyramid uses for the speaker wire inputs to the amp. If not you have to get creative, and make up terminals to fit into the input receptacles. Maybe a wire terminal from Radio shack will fit those pins..
Also, if you go on line: Google search "Pyramid auto amps" and click on "SEARCH" (upper right hand) of their Web Page. Plug in your model number like this, pb180, and you'll be able to download the manual for this amp. The manual has a full description of the wiring options.

Hope this was helpful and Good Luck!

is the positive cable hooked to the battery or the fuse box and it sounds like a grounding problem

If you get a small voltage signal from a jack labeled, "out" and put it through an equalizer, then to the jack labeled, "in", the equalizer will work.

Make shure your wall socket is grounded.Pull cover and look for black and wite and green wires on the back of the plug.Also may have leaking capacitors in final output stage may need a repair man look at the directory on this site.

you will need to show me a pic of the area along with the measurment of the pak from hole to hole and at least the voltage.

If the display is working, you have audio. Check your amplifier. 1300Watt adaptor ... This unit draws a very low power and that is not needed.
