Please help
G'day everyone first post on the forum.

I have a 94 celica and I'm looking to do a sub install. I have all the wires and everything but there is simply no visible gromit. Drilling through the firewall is not an option as is taking it to a store. Where the factory cables go through I have tried threading coat hangers yet they don't come out no matter how long I push them through. I'm using 8 gauge and I need to find a whole ASAP.

Any help is greatly, greatly appreciated.

Thanks in advance.
