Is it bad when you have a car stereo hooked up and when you hit the gas petal it makes a buzzing sound?

I have a jensen 100 x 4 amp that I use for my highs. Recently it started making the tweeter make a buzzing sound when I hit the gas petal, Does anyone know why it does this and how I could stop this ignoring sound?

it's alternator whine.





there are inductors that supposidly reduce this, but i don't know about how effective they are.





if all your wires are tight, it might just be that jensen makes junk.
Reply:3 different causes for this...





1. Bad ground. This is the most common. The ground on the amplifier is loose, poorly connected or to a bad spot. You need to have a clean surface... i.e. no paint and it must be tight on the connection.





2. Power intereference between the RCA's and the power wire. Electricity puts off a magnetic field and that can be picked up by the signal in the RCA's if they are routed together. Not always but sometimes this happens. Running your power wire on the opposite side of the car that the RCA's are on usually solves this.





3. Poor equipment. Some stereo equipment is just.... well.... garbage. No matter what you do.... run the RCA's from ANOTHER car, run the power wire only 12 inches, put the ground directly to the battery..... it won't take the whine out of the equipment. Trust me.... I've done all the above and still had equipment whine.





Good luck!

Reply:thats engine whine usually when you have a amp its usually becoz of the rca wires and power wires being to close together
Reply:yes this is bad. You have a bad ground.
