Default Radio fuzz when cathodes are on?

Hey Guys, I seem to get REALLY bad static on the radio with my cathodes on. Also, when they are on, and I'm using the aux input on the stereo, the sub power seems to get cut in half.

The Lights are tapped into the parking lights, the amp is right off of the battery (Fused). the power/signal wires are on opposite sides of the car.

Anyone know what might be up? Only thing I can think of is a stronger alternator, better battery, or adding a capacitor to the amp. Can anyone help me out? Thanks!


::Edit::
PS I searched before I posted but couldn't find anything...

Where is the circuit for the cathodes grounded? A poor ground can cause noise in your audio system. It is also possible that you have the transformers too close to your signal cable from your stereo. You do not want any source of power near your audio cables. Transformers can introduce HUGE amounts of noise into even the best shielded cables.
