Hi all, I've recently bought a 54 plate 3.0 td6 hse and whilst being a beautiful car it has in the last two days developed a terrible noise (screeching etc) from the dash speaker even when the stereo is off!! Was told it could be damp in the rear amp but it seems o.K?? Any ideas as it's driving me potty. Is it safe to unplug the amp connector or will it cause problems or need reprogramming or something.. Thanks Dan
