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.

i have a friend wit the same problem. What he had was a 4 guage power wire and a 8 guage ground. All we had to do was match the ground sizee
