General current draw.

Okay Just tonight I have started getting the old dancing lights on the dash and headlights whenever the sub in the boot went. My old orion had this but it was very slight and the Marea has never done it till tonight.

It was so bad that at the point before I thought enough was enough and turned the stereo off it starting cutting out.

Whats the first thing to check then?
As I'm assuming something must have broke considering it's the same setup has been in the car for over 2 years.

Cheers. Battery should be okay was only replaced last year.
Will check the earths tomorrow. Think it might be as simple as a loose connection?

It might just be a loose-ish aux drive belt, i would also look at the condition of the connections on the battery as they can corrode.
