Hearing a whine through speakers?

If you are hearing a whine through your speakers, it could be one of 4 things...

* Alternator whine

* Signal wires/RCA's too close to your amplifier power cable

* Head unit grounding

* General grounding

Firstly, make sure your patch cords are running on the opposite side of the car to your power cables. If the whine is still there, the easiest and cheapest way to silence it would be to purchase a Ground Loop Isolator (Average price is £8.00 for a decent one). If that does not work, check your grounding. Find a good ground spot that has no paint (A good place is removing the seatbelt and using the seat belt buckle end bolt with a ring terminal. File or sand the area so there is no paint, and that should do the trick.
