im looking at installing an amp and was wondering if its fine to go through the firewall were there is already a group of wires with a rubber seal, i was thinking of poking a hole through the rubber seal and running the power cable through there would this be a suitable option. Thanks
Of course you can. As many amps that I have installed I have only had to drill one hole through the fire wall. As long as there is a grommet you are good to go. You should be able to open the rubber up with a screw driver. Just be careful not to damage any wires.
