I have a high pitch "squeal" that sounds like the weather warning tone that comes on the radio occasionally on my radio all the time. This just started coincidentally with my window regulator going bad...Anyway, the squeal is over the sound of whatever is playing,radio/cd/ipod, with the car running or not. Its all factory nav unit. I am considering just changing out everything anyway,radio/amp/speakers. I am not looking to install the baddest system in the land so I was thinking of just reusing the existing speaker wires. I dont want to hack it up so was wondering if there is a female plug end for the amp end under the seat. What have you done? I have looked at a bunch of stuff and cannot get any positive fitments for this. Thanks.
