Hi Karan

To be honest I remember removing one of the rubber gromets and checked the other side on the firewall to ensure I drilled through the correct one and then fed the wire through.

If you can see just electrical wires on the opposite side then I would not reccomend you doing this yourself as one mistake can **** up the whole cars electrics if you are not sure.

hey thanks alot for the info. drilled through the gromet and fed the wire through to the battery along the other wires. . ran it to the back all inside the covers. gonna put the amp under the back seats. ran out of time so going to carry on tomorrow. thanks

That's great hope the step by step helped.
