ummm... my Sony BT3900 basically turned itself off?, after going over quite a hard bump it just did it's typical three sony turn off sounds, and then poof no power, but it let me eject the CD so I am sure it still has power, only earlier on in the day i was fiddling with the sub and two amps i have, but it worked fine for a good two hour drive..
Someone please shed some light on this please, otherwise its gonna have to be lonely in there!

cheers ash
P.S Ruckus, i know you know a lot so come gimme a hand here?
