have just reinstalled my mp3/cd head unit. and everytime a song changes or i press a button, a thud comes through the speakers. is this a head unit problem (somehow i dont think so). or have i stuffed up the install?

1st thing is to double check your ground for the headunit and the speaker connections. Did you use a harness or cut into the factory wiring?

You'll probably find that if you run a new ground wire you might remove the problem. But if it is doing it direct from the battery than i suspect it is either a low quality unit or there maybe something wrong internally.

Try tapping the battery for the +, but ground the headunit (-) to the chasis of the vehicle (less then 3 feet away, clean bare metal). You normally don't run both + and - to the battery like you mentioned you tried above. Make sure you fuse you + wire within 18 inches of the battery with an inline fuse.
