I just installed 4 brand new speakers that are running through a brand new amplifier. When I start my car, there is a faint buzzing/whining coming from my speakers. When press the accelerater down, the sound gets louder with the more RPM's. Anyone know whats up?

you are probably running your signal wires along side of your power wires. run power cables down one side of car and signal wires down the other. if this does not work then go to grounds, but do not buy a noise filter, this is a cheap way out and your problem will most likely come back.

Engine Noise... the old enemy to all car audio installers!
Believe it or not, a book about engine noise should exist by now! There are a verity of factors, causes, types of noise and solutions out there...It is mind boggling.
Noise filters sometimes work good and sometimes make it worse (i.e. Signal loss, quality of sound degraded, R+L ch balance mixed up...)
First, as always, I would use the process of elimination. But to do that you have to have a wide knowledge of the causes of engine noise and if you don't, I would take it to a local stereo shop to diagnose the problem and fix it.
I have dealt with all faces of the evil noise, and believe it or not, sometimes shielded RCA wires can be the cause!! Try buying some cheap RCA wires and run those instead, sometimes, it magically works!. If it doesn't, there are still 100 different things u can try!

sounds like a bad ground wire. trace the ground wires, usually black, and make sure if they're attached to the body of the car that there is no paint or oxidation between the metal and the ground connector.
Also, you might want to think about the spark plug wires. old wires will have broken down silicone jackets and RFI can leak through.
when you accelerate, more voltage fires thru the wires, it makes sense the wires need to be looked at.

you are probably suffering from somthing called a ground loop, check you grounds try to keep as few grounds as possible like 2 or less, incuding the head unit.if not somthing isnt insulated very well, or if you have an amp and your power wire is running up the same side of the car as the RCA's they might be picking up interferance, run them on differant sides of the car...

wiring maybe too close to the the wiring harness of the car and is picking up interference. or also there maybe grounding wire issue. you may need a noise filter. go back to the shop who installed the speakers or if yo did it recheck connections.

Its noise (electrical fields, not sound waves) from your fuel pump effecting the signal to your amp. its a very common problem. You can get filters for it from most good quality audio shops.

Whoever installed your system has it hook up on a bad ground. You are getting feed back noise from the altenator.

oldguy is right, a "noise filter" will do the trick, but Radio Shack quit carrying them, go to Best Buy or the like.

sounds like ground loop. You can try to reground your amps and cd player, or you can get a ground loop isolator. They usually work pretty well.
