My amp is all hooked up right and i have a green light and the red light is on but no sound...what does that mean?

on some amps there is a duel light. red and green usually. red means it is in protect mode or you didn't hook up your remote wire. if in protect mode, it could mean a number of things. did you hook it up with speakers and everything?

Standard wiring colors are as follows:

4-Way

5-Way

6-Way

7-Way

Green

Yellow

Brown

White

Red

Blue

Purple

Right Turn & Brake

Left Turn & Brake

Tail Lights

Ground

Backup Lights

Electric Brakes

Auxiliary Power
Green- Right Turn and Brake
Yellow- Left Turn and Brake
Brown- Tail Lights
White- Ground
Red- Reverse (Back Up) Lights
Blue- Electric Brakes
Purple- Auxiliary Power

It sounds like your green and yello wires are shorted together somewhere along the length of the harness. I would check the wires on the trailer first. Easier yet, if you have another trailer to connec or access to another to use for testing, connect to it and see if the problem repeats; if it does the trouble is in the vehicle's wiring.

Sounds to me like the amp is going into protection mode. Try placing one sub on the amp with very little gain. One of the biggest reason why this happens is because the subwoofers are wired wrong. What is the brand and model number for your amp?

make sure the blue remote wire is hooked up too, and match the wiring diagrams,hope it helps and make sure to vote for me

The red light on amplifier relates to power supply while the green light is indication of sound functionality. An amplifier that allows sound to generate should display both red and green lights. Howeever, some amplifiers would display only green as long as the sound is functioning.

Solving the problem

First, a red light still on means the power connections to the amplifier is fucntional least requirng repairs.

Second, the green ligh should turn on once the stereo were tuned up to produce sound. If the stereo is still on only least produce sound on the amplifier, check on the connection wires between stereo to amplifier that may have disconnected due to woofing or dubbing sound generals with unfirm wiring.

Third,

1st check all of your wiring, make sure the remote wire is hooked up, check to see it the RCA's are hooked up. I know this sounds stupid, but i've done it a thousand times, check to see if you hooked up the speakers. If you checked all of those and still nothing, double check your ground. Make sure where you have it grounded, you have all the paint sanded away and its a good grounding point. The red light on the top of the amp, its not a protection light is it??

some parts are damaged ,maybe audio amplifiers IC´s or power fet´s

You need to check your woofers. Most likely one or both may be a) blown or at a dead short or b) the ohm rating on them may be too low. What model woofers and amp do you have??

Sony generally drives their power light from a source that does not rely on the amplifier's switching power supply. This means that it's not a good indicator as to the health of the amplifier.

 

As long as you have B+ and remote voltage, it will light up. Since you've tested the speaker and the signal source, I think the amplifier is likely defective.
