Firewall wiring & grounding points

[razzledazzle]

Alright folks, first post here. I've got a subwoofer to install on my 97 ep91 starlet, and was wondering if anyone could help me with where some easy grounding points are (ideally within the cabin / around the passenger seat area) as well as where to find the firewall to trail the power cable through to the battery?

I could take the dash off and peel back the trim to find out myself but would appreciate any hot tips.

Cheers lads!

e: found a decent ground point underneath the footwell panels. still struggling on where to feed the power cable through to the battery though.

Found a grommet in the footwell just under the trim but the fuse on my power cable won't fit through and there's not enough length in it to get from there to the battery. started raining so left it there, next port of call is dash removal

in the glanza ep91...looking from the front of the car, i feed wires through a rubber grommet on the firewall on the passenger side...kind of behind the battery ...it feeds through to behind the dashboard behind the glovebox area...you can look for the wires from the passenger footwell area with a search light.

i tend to use a slightly harder gauge wire to feed through at first and then tie the other/softer wires to that and pull them through

hope that make sense
