No volume from speakers

Maybe a shorted speaker causing the power amplifier inside the radio to shut down or a speaker wire shorted to chassis and last the internal amplifier of the radio cd set faulty by itself... set volume to zero power it off take out the radio cd set; remove the speaker iso plug leaving the power plug only in and power it on if necesary turn again the volume down to zero and wait if it keeps turned on it a speaker problem if it shut itself off again then you go for a repair or a new one

You need to run RCA cables from the CD player to the CD or AUX input on your amp / receiver unit. If you have a standalone amp, you need some way to control the volume. Basically, if you have a volume control on the front of your amp, you're OK. If not, you should also have a preamplifier that the CD player feeds first.

From the amplifier, then, a single pair of speaker outputs feeds a single pair of inputs on your speakers. The reason for two jack sets on the speakers is for "bi-wiring" or "bi-amping", not necessary for basic stereo reproduction.

So -

CD red/white RCA out -> preamp/receiver red/white CD/AUX input. Amp speaker output (red + / black -) to one red/black input pair on the speakers. An input on the speaker is side by side...

Keep the red to red, black to black when connecting the speakers, or you will wind up with poor sound and weak bass.

Hello, the protect circuit is likely detecting a damaged speaker or speaker wire.Check the unit with one speaker at a time connected, or if you have an ohmmeter measure each speaker they should read approximately 8 ohms.When you connect a speaker thats bad the unit is designed to shut down and flash protect.

Clipping occurs when an amplifier is pushed to create a signal with more power than its power supply can produce. The red light flashing is warning you that your are overdriving the amplifier located in your speaker cabinets. This can cause damage to your amplifier and or your speakers. You should not allow the volume level to exceed clipping.

ok, the red and yellow wires serve 2 different purposes.the yellow supplies constant power to your stereo, and the red is switched power. what youve done is combine the two, and connect them to a constant power source. like this, your stereo wont be switched with your ignition. so take off the red wire, but leave the yellow wire connected to the wire its already on. make sure your stereo fuse is good in the fusebox of the car. then, use a test light, with the ignition switch on, to find the second wire on your cars harness that has power. that will be your switched power. connect that one to your red wire, and that will solve your problem.

Check the chassis ground connections. If you have electric fans and no power, this could be keeping the fans from running when they ate needed. If everything electrical is acting up, I would check for a common problem like a main ground loose, corroded, or not properly installed. You need good metal on metal contact.

Red - Power
Yellow - primary power must be joined to the red
blue - Remote
Black - ground or negative
To find your speaker wires check the color of the cord behind each speaker than match it with the same color in the dash.
or the easy way is to use a normal 1.5v penlight battery and try each speaker cord behind the dash and listen to which speaker give off a crackling noise so you can get the balance on the cd player right.
If u trying to find power in the car and don't have a tester than get a 12v light or bulb join the negative to the body and push the positive wire into each one of the holes in the factory plug in the dash one at a time until the light comes on. That is your positive the rest is easy. (DIY guru)
