Yes amps from Infinity, Sony and many others have led's built in.
A typical car stereo contains 4 amps. It is rare to find a car stereo without amps. Cars usually can contain up 8 amps, but you could always add more.
You need the volts times the amps to equal 100 Watts. On 12 v that is 8.33 amps, or on 200 v is it 0.5 amps.
They light up because of the filament in the light
this question is kinda split into 2 answers. 1. total amps available to your car thru it's battery can be 500, 600, 700, etc amps 2.fused amps are restricted by the fuses, say a car radio has a amp draw of 5 amps so the fuse thru that circuit would be rated at 5.5 or possibly 6 amps to protect the component . So total amps " used " in your car is simply added up all the fuse ratings of all the fuses in the car and you will be close.Now if you add excessories then the amps will increase with each item added. One side note, the battery itself and the car have connected a special fuse called a fusible link to protect the whole car from say a bad short so say a 500 amp battery does not burn the car or explode the battery .Hope this helps.
Any mechanic with a code reader can get them from the car then you can look them up online.
The Legacy Car Audio LBP22 has leds around the subwoofers that light up.
Use a mini 30 amp fuse. If it blows then check for grounds with a test light. If know ground is present, then you can step up the amps in intervals of 5 amps until the fuse doesnt blow.
This was the case in my wife's 1997 Pontiac Grand Am. Couldn't figure out why. But, when the original alternator went recently, the mechanic also noted that the battery was under the recommended amps recommended for the car. Now with a new alternator and a new battery with plenty of amps the radio display is fine! Answer: The radio might have connection which dims the light when the lights on the car are switched on. This could be wired up wrong.
It depends on the alternator. Some only put out around 40 amps while others that supply power windows and heated seats may put out around 120 amps or greater. Some heavy equipment and buses put out around 300 amps. Best way to find out is look up the specs in your owners manual or call your dealer with the make and model of your car.
Jack the front of the car up and crawl under it and pull any plastic down behind the light and then you will be able to get to the bulb.
If you are referring to a car and not a home theatre set up than most likely your problem would be "engine noise". The inner workings of the car create low level frequencies that you normally won't pick up. But when you use amps, which AMPLIFY frequencies (sound) everything can get amplified. There are several devices to block but their operational success depends on the position of your amps and radio. The best way to insure your amps don't pick up engine noise is to use sheilded wires.
Yes, you do.
