Hi Micah, What Amp and leads do you have? Your passive speaker will need to be plugged into your amp speaker outs , and you radio into your Amps Tuner/Radio input or Aux, but just depends what system you have. Check what inputs and outputs your amp has and what leads you need as a lot of systems need different setup and cables/leads.

Peavey color indicates that Blue is Negative And Yellow Is Positive, so Yellow goes to + Speaker Terminal.

2 possibilities here:

*Speaker coils got fried or,
*Input jack named "Low" in the Bi-Amp section has a loose contact, as they are switch also.

Hope this helps.

First of all i need some more information, such the power amp you've hooked to them rating in watts and please specify if you are not getting sound from tweeter or 15" BW speaker or both of them, this way i can improve accuracy helping you out.

For the MOST PART the lamp is NOT the primary path for the speaker current, the POLYFUSE is and is a low resistance until it is overdriven.

The bulb is a 12 volt bulb and is nominally 2.1 amps when used on 12.8 volts.

If this is in regards to the other problem mentioning 32 watts and 12.8 volts... this bulb is NOT 32 Watts, it is 32 CP or 32 Candlepower which is NOT Watts in general. The lamp is actually around 27 Watts when run at its ratings.

It is important to realize that the lamp and the resistor are there ONLY as a "soft" path when the POLYFUSE opens due to overcurrent. When the polyfuse cools, the lamp and resistors are effectively shorted by the Polyfuse and most of the current again flows through the polyfuse..

The lamp is an "1156" lamp... replace with that part number. Here :


Or you can find it at auto parts store.

LIKELY the polyfuse device is ALSO gone... Probably similar to this one (1.1 amp, trip 2.2 amp):


or this one (1.85 amp, trip 3.7 amp):

These cabinets are self contained and you do not use a crossover with them. The speakers do NOT come out to separate connectors. You just drive these with an amplifier. DO PAY ATTENTION to the power rating... you are safe using an amplifier with a MAXIMUM of 150 Watts RMS per speaker cabinet. More than that and running them loud and you will be replacing the speakers. These will cover a 40 foot square room at comfortable level.

Hi budprice54,
High chance that both of them was blown due to high frequency signal from the amplifier. You may confirmed it by swapping with a working one or if not available test the incoming audio from the two speaker wire connected to this speaker with a multimeter set in AC. There was a small flactuating voltages reading depends upon the beat of the sounds if the audio signal was present.
If confirmed that the speaker was already faulty, there some shop specialized in speaker rewinding, this speakers need to replace the voice coil to work again or you may replaced it with a new one.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

This makes no sense... 32 Watts and 12.8 volts... something to do with this speaker that is rated at 500 Watts???

If you are trying to calculate something for a car amp you don't understand how they work... that is the only thing I can think given the 12.8 volt thing you stated. Most high power car amps BOOST the incoming battery voltage up with a switching power supply. For instance, they might boost to 48 volts and that applied to a 4 ohm speaker would be 12 amps PEAK maximums. BUT the RMS power is one half that or about 288 Watts in round figures before considering losses.

Many car amps are designed to run with 2 ohm speakers... JUST SO THEY CAN CLAIM massive power values in their ads so you will buy them!

Here is a link to forum that someone has posted the soundguard protection circuit down the page:


The 1156 lamp MAY have slightly different shapes but is an automotive lamp. If the bulb is blown, the polyswitch fuse is likely blown as well.

Find them at Digikey.com. Search first for "Capacitor" then select "Non-Polar"

HOWEVER there is a part that LOOKS like a ceramic capacitor but it is NOT. It is a "polyswitch" which is a resettable fuse. Go to the Digikey.com site and search for "Polyswitch". Then select 60 volt in the filter and Radial... see if you can find the item. Also consider opening a second speaker if you have it to get the number off one that is still OK. This is part of a protection circuit and needs to be replaced with exact device.
