how when i turn my amp on to power my subs certain stations wont come in when its on only when i have the switch turned off?

 

im not sure, but some random thing happens in my car... when i have my heater on high, some radio stations wont work lol.... maybe something is happening like that? probably not though, just wanted you to consider an option lol

 

is everything wired correctly and free from each other? sounds like you might be getting interference from the wiring from the amp maybe

 

try taking it out and putting it back in.
