Your stereo is picking up alternator whine. If you're good, you can make the motor fit with the song... kidding.
you can purchase a noise filter that will fit on the ground line of the alternator.... here's a few to scope out online

this will get it out for ya...

How do i get the best sound from my infinity 1250w subwoofers


Make sure the ohm's are the same on all your speakers and amp.
You amp watt should be equal or higher then your speakers total amps.
You base box should be completely air tight, and have about 1/2 of the box stuffed with cotton.
Make sure you use a good thick speaker cables to connect from the amp to the speakers.
and finally, make sure your trunk seals tight and wont rattle... cause nothing sounds worse then someone pulling next to you and all you hear is a buzzing sound from the trunk rattling... Also... sell the infinity's and get something like memphis, or panasonics. :P

High dinging or ringing noise Under hood


if it goes away when you turn the a/c on its the a/c clutch plate that is dragging and when you turn it on its pulled into the the a/c compressor and is turning all the time that's why noise goes away,you have to replace the a/c clutch.sometimes you can try prying with a screwdriver the edge that is dragging and noise will go away.

How do I remove the "needs Maintainance " code. Is the interlink sunvisor a plug and play accessorie? Is the compas mirror also a plug & play accesorie? Are there any reputable salvage lots that...


The maintenance light goes away like this:
1. Turn the ignition key in 'I'-position
2.Press the trip odometer reset button (make sure that it is showing T1. Make note on the mileage).
3. While keeping the reset pressed down, turn the ignition key to 'II'-position.
4. Wait until the service light (or the yellow triangel) has blinked three times or the trip mileage has returned to show the previous mileage (not reset to 0.0)
5. Release the trip reset button.
5. Release

Fuel system on infiniti 1999


Turn key forward and listen for the fuel pump to kick on. It will make a high pitched sound then shut off. If no sound the more than likely you need a fuel pump. You can check at the fuel rail with a guage pressure should be 30psi.
