Question about Car Amplifiers

1 Answer

Car stereo a new car stereo with the help of an adaptor all fits and works, Thought that when the car lights are turned on the lights on the raido come on, a bit strange. There is a red wire which must be the positive lead, live feed, it has a tag on it saying this might have to be conected to the ignition or the battery could go flat, and yes the battery has gone flat. What do i do???is it i cut the red wire and connect it to a wire coming off the ignition,,, I took off the face plate to the stereo and there is a red light, on. Clearly the stereo is still drawing power from the car battery even when everything is turned off.. pls advise

My amp stopped workin, when i turn the stereo on, the green light is on, then when the music starts to play it turns red and stops working,


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.

Today i turned on stereo system driving in my car, and i have 2 12"inch t1 Rockford in a box with kicker zx300.1 it all hooked up on my car for like weeks ago and work great, but today it stop working...


Hello charlietmn,

First off you need to turn your vehicle on, turn the stereo on. Go back and look at the amp. Do you see a power light on ? Is it green or red ?
If there is no light or a red light on, your amp is not getting power or is not grounded correctly in which you can try the following:

Check and make sure your ground cable is grounded properly. It should be attached to your vehicles frame on bare metal.

You can also check your fuses, in your amp, and in the power cable for the amp.

In my experience installing car audio, those are the two most common simple issues.

Post back after you've checked the things I mentioned. I will assist you further if you need further help. Thank you for choosing Fixya and have a great day.

Install dual xd1222 into a 1993 dodge intrepid


The best way is to get a stereo installation kit designed for your car. It will have the surround for the new stereo to fit where the stock stereo fit. Also, it comes with a wiring harness that you connect the new stereo to then it plugs in to the stock radio plug. Most local automotive stereo stores should carry them.

Red Power Protector light


Hi, the only way i can see the amp resets the stereo is that power is dropping. The amp should have its own wires directly to power/battery so as to not affect anything else.

On the protect, try to disconnet all the speakers, make sure the power is OK. If it appears to work, the there could be a problem with speakers/cables. Try a different speaker to see if it works. If the problem continues with speakers off, a different speaker etc, then there is a problem with the amp. Hope that helps

Powers on but no sound


Check the main amp fuse under the hood, even if it looks good just change it. Often times that light on the amp can come on just from the power amp tunon wire. Try a friends subwoofer box just to make sure the connectors on your box are good, and if that doesn't work then give me some more details....year/make/model of car, what kind of sub, what types of things do you see on the side of the amp....is there a green light as well as a red light?
