thanx but i would like to put mine threw the firewall does anyone know how is done where is the hole and another question can ia disconnect the -(minus) cable of my batery without harming the car pc?

all you need to do is either run it through where your wiring room goes through by cutting a small hole in the gromit or drill a new hole in the bulkhead and fit a new gromit in there and put the wires through. and you do not need to disconnect the -ve terminal at all.

have a look behind the carpet on the right side of your boot, you may find an answer to all your problems. a connector for factory sub,

Undo the scuttle panel and there is a massive grommit there that needs to be cut to put a wire though.

Connector for the factory sub is crap tbh and a waste of time for anything other than the standard sub.

Disconnect the battery aswell. Its not wise to work on the car with the battery connected.
