I drive a 98 Saturn Sl2 4 Door

When im driving and accelerating There is a loud Pitch in my speaker'* and It Automatically Shuts off my after market amps and Subs, it does it with Am/Fm, Cd, Usb, and AUX Even When i have it on aux and Nothing plugged in it does this, im unsure what to do, i kno its not my amp bcuz most of the time when i start my car is will Work for o about a song or to so Somewhere around 5 to 7 mins Useally, then it happens I dont know what to do about this ive check my connections in the back of my aftermarket Deck checked the wires there they were good and all connected, checked my fuse upfront fuse is running fine and Connections are great Checked the leads to my amp There okay, an Checked the leads to my speakers there okay, And gonna check the ground, BUt i dont think thats my problem


Thanks ,
Sean!

did you use good shielded rca cables to hook the hu to the amp? the other causes for interferance are bad grounds, running the power and signal cables together, or possibly a fault in the car like needing wires/plugs, or an alternator fault.

have you had the alternator and the battery tested lately? Do the rest of the lights in the car fade when this happens?
