Leading cause of this problem is overheating of car stereo due to the wrong connection of the wires of the car stereo.
It can also be caused by when the amplifier of the car is on safe mode. In a safe mode of the amplifier, green lights show that means everything is good.
While a red light indicates the alarming condition that the problem could be in the wires or another component.
this problem can be solved by checking the voltage of unit head that should be 12v. Check it by voltmeter if the voltage is provided completely then it means the problem is in due to another reason.
But if you find that wires are not providing 12v then change the wires. It can also be caused by the blown fuse you can also check the fuse for this problem. And by changing the fuse you can overcome this problem.
Speakers lack bass:
This problem is mainly caused by car stereo overheating. It occurs when new aftermarket speakers are installed or repaired and then installed in place of factory speakers.
As we know that bass of the speakers requires the push of the air and pull off the air. One speaker pushes the air and other speakers pull the air. So overheating stereo or damaged stereo do not work properly and newly installed speakers lack the bass.
Factory speakers require less energy for the bass while aftermarket speakers are heavier than the factory speakers.
this problem is caused by when car stereo is dirty or the wires of the speakers are not connected in its respective way. That positive terminal should be connected to the positive terminal of the stereo and the same for the negative terminal of the car stereo.
For the no bass in speakers car stereo requires extra watt for this so an external battery can be connected to it to give

When car stereo heats up then noises are heard you can get rid of this problem by setting the capacitor between the power wires and ground wires it absorbs unnecessary sounds prevent from transferring to car stereo system.
If speakers still popping then change the channel and check to wither sound seizes or not if yes then it could be the problem of radio channel if not then replaces the car stereo or speaker.
Sound cuts in the audio system of the car due to overheating of care stereo or it can also be caused by loose wiring of car stereo or speakers.
