Problems
My speakers make a buzzing noise when i rev the engine, or just constantly buzz no matter what i do
Why are my speakers constantly buzzing?
There are a few possible causes for this. Some of them are very simple others are not.
I will start by listing the most simple, and giving solutions. If you try all of these and then get down to the bottom end of the list its likely one of them will sort you out.
Solution: re-route the wiring
2. Is the alternator causing interference?
Solution: Fit a ground loop isolator. This is basically a coil of wire, which hides interference. Be careful not to wrap this in other wires or place it on top of an amplifier, as this will make your original problem a lot worse.
3.How close are the amps to each other?
If you have more than one, try moving them as far away from each other as possible.
4. Are the RCA leads of significant quality to be used in a car?
It may be that whatever you do your RCA leads are going past an electronic device. Try upgrading to twisted RCA leads. Alternatively you can wrap the suspected areas with tin foil to stop interference from entering the wires.
5. Is the Earth cable touching pure metal?
Solution: Use a wire brush to clean up the surface that it is fixed to. Try to make it shiny metal. This way it will have the best possible connection.
6. Is this coming from the head unit?
Try another head unit. If this solves the problem then it is likely that your head unit has the earth tracking blown. A cheap solution to this is to joint wires from the outside of the RCA plug to the cage of the head unit. Alternatively you can get it repaired, but it can cost as much as 60 pounds, for a relatively simple job.
How did this happen to your radio?
Whenever you are playing around with your amps, u must remove the RCA leads first, and make sure that they are plugged in last after you finish working. If for example you remove the earth lead from your amplifier, it will earth through the RCA leads and blow the earth in your head unit.
My speakers are crackling and not producing sound like they used to
My radio forgets its settings each time i switch off the cars engine
Questions:
How are watts or power calculated?
