I hooked the amp up to my second battery in the back of the blazer and the sound ticking sound went away. when i hooked the power wire from the front battery to the back the sound came back when the car was running. so, i am gonna assume that is where it is comming from lol, just don't really know how to go about fixing the problem atm. what would be causing sound to come back through the power wire? i have a new alternator because the old one died. and this amp is just to my mids and highs.
oh, and btw, the sound isn't just comming from the tweeters, it is also comming from the other speakers as well.
