need help with my stereo
 

When I use my amp to power my subs, it produces this annoying noise and especially when I turn on the engine. Its like I can hear my engine through my speakers!!! I have checked all my cables and ground wires and it still does it. What should I do next??? Im almost ready to explode.

First check your amp ground. Make sure its connected to a proper point on your car, and not just some random piece of metal. If you're still getting a whine, get thicker ground wire. If it still doesn't go away, search google for the 'big 3', and make the necessary changes. One of these options should solve your issue.

This is actually answered in this Months Car Audio and Electronics Magazine. It maybe on their website,
