    I just finished an install on my 51 chevy. When the car is off it sounds aaamazing, but once I start the car it sounds like garbage.

    Here are the specs:
    pioneer head unit
    Boston acoustic 6 1/2 speakers front and back
    Fosgate subs
    Orion amps
    Monster cables

    The car has a 350 v8 with a new alternator and battery. It's carbureted with an HEI ignition. Why would it sound so bad when the car is running?

    What is happening when the car is running? I'm assuming you're getting alternator whine through your speakers.

    I am getting a crackling sound thru the speakers. It happens no matter what input I am on. Cd, iPod and radio are all the same.
