I can listen to the stereo fine as long as I don't start my car but if I start it a weird sound comes through the speakers and gets louder as RPM builds. Is there a way to get rid of this or is the amp screwed? I just replaced the battery and the alternator. And was told that it could be a bad ground but I have reran the ground and shortened it and its still making the sound. Thanx
The problem is not likely the amp. The length of the ground to the amp is not as critical as a good solid connection. Clean any paint and dirt from around the ground connection. It should be clean and shiny metal. Anyway as a test disconnect the RCA's from the amp while the amp is on and see if the sound goes away. If it does then the problem is not in the amp but either the RCA cables, the RCA grounds in the head unit (radio) or bad routing of the RCA cables. Depending on the how old the car is this noise can be coming from your spark plug wires as well. As a last resort you can try a new set of supressor ignition wires for the car.

Open up your computer the speakers plug/outlet is usually at the back of the computer as is the microphone input to check the lead attached to the rear of the input plugs make sure the connections are good or you might have to clean the dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your sound card dust causes static to build up in a computer causing it to overheat any many other problems be sure to wear an anti static earth strap before touching anything inside your computer hope this helps

have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or click start control panel administrive tools computer managementdevice manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your sound card dust causes static to build up in a computer causing it to overheat any many other problems hope this helps don
This is the test tone for the speakers, usually means you have connected the input lead into the diagnostic port. The input leads plug into your computer/ipod/TV etc. there may be 2 of them but you only need one plugged in.
It may sound silly, but can you check all your speaker cables again and confirm whether they are connected to the right connections. please check all cables as also the severed one and please repair it also.
Now please go to the system-set-up and do an auto setup and set up your speakers. Listen to the test tones and confirm that they are coming out of the correct speaker.
Once these are set, then if still there is mismatch of sounds, then we could further trouble shoot.
to localised your problem, try to plug your speakers to other sound source like mp3 player ,stereo system. if still no sound coming from it,your problem is within the speaker system. perhaps the audio power amplifier ic inside, need to be replaced.
This is really weird. Normally, the subwoofer must be turned off when you turn on B speakers. But, hold on.. I have recently tried to do the same thing as you do, and the result is the same as yours. The problem is that you have to turn off A speakers completely when you activate Bs. If you have an A/B Speakers switch, first push the A to turn them off, after that press "B" to listen to music downstairs. I hope it works.
