Most likely a bad earth. I'd start with the light cluster and clean all the contacts and the earth connection.

As Taurus says, it is probably down to high resistance in the earth connections of the lamps.
I would think that the only way your sub & amp could have any effect, is if they are sharing the supply or earth connections. In any case, it is easy enough to find out, just switch 'off' your sub/amp and try the lights - if the problem is still there, it is nothing to do with the sub or the amp.

Regards.
