Speaker Noise

[sharpeaveo]

So I just upgraded my front speakers Kicker KS600. I hooked them up to an amplifier ZX350.4 and when I turned them on I get all this noise. The left speaker has a whining noise that changes pitch witht the rpms of the car. The right speaker makes a quieter ticking noise. I have my power wire running down the drivers side and the rca and speaker wire running down the passenger side. I have the amp in the hatch with the ground wire connected to a bolt for the back seat bracket (there is a pic of this in another post that someone else grounded at the same point). I kept the factory head unit. Any ideas on how I can get rid of this noise? I've never had it happen in any of my other cars. HELP!

if you installed only the speakers its probably a ground issue. if it happened after installing a head unit, its probably a shielding issue. (or power to radio is pulsed).
