You will find several noise sources inside a vehicle audio setup. In the following paragraphs, I'll discuss one where your vehicle loudspeakers produce noise that appears to improve whenever you "rev" the engine. You'll be able to learn to eliminate that annoying noise and revel in your own music.
First, you must realise that this is just interference or caused noise. Caused noise can seem like clicking, popping, whirring, buzzing, whizzing, or whining. This noise has a resource like the alternator, vehicle energy wiring, amplifier, etc. So which means that the issue could be handled in the source. Now, you just need to think it is.
Energy line noise problems (for example individuals from alternators) could be fixed with the addition of a capacitor or energy line filter towards the live supply of the suspect component.
Another place to investigate may be the earth, also called ground wire, towards the rear from the radio or mind unit. Try managing a new earth or ground wire in the rear from the radio to a different position (earth) around the car's chassis, changing the present earth wire.
For those who have installed a guitar amp, be sure that the RCA cables running in the mind unit towards the amplifier have top quality. Also make certain they're run across the vehicle from the car's existing wiring and from the amplifier's energy cable. With regard to testing, try running the RCA lead loosely between your mind unit and also the amplifier without really running them underneath the carpet. "Rev" your engine using the radio on low volume if the noise is finished.
If you've still got the noise, consult a vehicle audio expert. You will find a couple of things in vehicle audio that need expert assessment. There might be a substance problem. A great vehicle audio expert is much better outfitted to identify the issue.
