Where do I connect key 1 and key 2 wires?
Key 1 and 2 are used for steering wheel control as well as some other applications like radios. You need to connect the key 1 or key 2 with the original steering wheel control wire. The button light control wire is referred to as “Illum” wire.
What does Key 1 and key KEY2 mean?
The Key 1, Key 2, and Key GND wires will be used to interface steering wheel controls if your vehicle came equipped. Most newer vehicles will also need the Axxess ASWC-1 to translate the steering wheel controls to this stereo.
What does KEY1 and KEY2 mean?
KEY1, KEY2 and GND are the control lines for old style Steering Wheel Controls (SWC). The old style SWC are analogue and appear in very old cars. Cars are no longer made with that system fitted. But, the KEY1 KEY2 analogue has become a standard for manufacturers to use when making connections to an Android Headunit.
What wires are for what on a car stereo?
The right-front speaker wires are gray, left-front speakers are white, right-rear speakers are purple, and left-rear speakers are green. Ground wires are black, antenna wires are blue, and amplifier wires are blue with a white stripe.
How do you tell if you have a bad ground on your amp?
It can make your amp cut in and out or if the amp is restating. Whining or popping or any audible noise that isn’t normal. Can cause burning or even a fire! So post some pics of the grounds and the distro block that is welded.
What happens if an amp is not grounded?
a bad ground (or no ground) would prevent an amplifier from turning on. not connecting a 12v+ remote turn on wire, would too, prevent an amplifier from turning on. a blown fuse from a spark will prevent an amplifier from turning on.
Will amp turn on if not grounded?
Without a ground the unit shouldn’t even power on, as the current has to make a loop from the positive terminal to the sub then back through the ground cable and back to the battery via the car chassis. Ground is just a trick to avoid running unnecessary cables and will not damage anything if its not connected.
Can a bad ground cause an amp to go into protect mode?
Ground Problems In some cases, a loose or shorted wire causes an amp to go into protect mode to prevent a more serious problem from occurring. Diagnosing and fixing this requires checking each individual power and ground wire.
Why does my amp go into protect mode when I turn it up?
If your car amplifier goes into protect mode when you turn up the volume high on the car stereo its usually because of voltage drop. Basically when you listen to your car amp at high volume levels it goes into protection mode because there is not enough power from the electrical system to chuck at it.
What do you do when your amp goes into protection mode?
If you find that one pair of speaker wires or one speaker causes the amp to go into protect, disconnect all speakers from the other end of the wires and separate the wires so they can’t touch. If the amp still goes into protect, you have a bad speaker wire or the wire is shorted to chassis ground.
Can a bad ground cause an amp to overheat?
Amplifiers can overheat when the ground connection is poor or became loose. The most efficient ground connection is direct wiring from the battery, but then this is not possible we use various bolting points in the chassis to connect the amplifier.
Why does my amp shut off at high volume?
If the car stereo or amplifier powers off when raising the volume, then there may be an issue with installation. This usually occurs when the ground wire is not connected properly. However, it also can occur when an amplifier becomes overloaded by connecting too many speakers.
