I have a problem, i'm installing a new soundsystem, but i'm one of those unfortunate cases where the battery is at the front of the bmw (1995 318is coupe)
Now I cant get my cable to the battery from underneath the dashboard and vice versa. ghead
Does anybody know how to get there (where some holes are placed) I am not able to drill a hole and im not leaving my hood and my door open and leave the cable outside :P
It wouldn't matter if the fusebox was in the cockpit, you need a much better power source to power an aftermarket amp.
The firewall should have an opening that is easily found. Pop the hood and trace the wires, most likely it will be on the lower portion of the firewall and it will be easier (once located) to run your power wire from inside the cabin into the engine bay (not vice versa).
If you plan on using a single amp configuration, 8AGU wire should be sufficient. IF you plan on installing a multiamp system, go with at least 4AGU power wire.
I have traced every wire under the cockpit and dashboard/glovebox and they all find their way out through somekind if plug wich only has space for those wires.
But here is what I did, I removed the battery, drilled a hole from the engine compartment to underneath the glove box and hot glued the oversize of the cable hole.
Also today i installed the tweeters in the doors.......my god (it has cost me a day)
Especially when you have to drive a thick speaker cable through that rubbery-thingy between the chassis and the door.
I just finished installing the cables from my headunit and the speakers in the kickpanels.
Tomorrow im going to run all the cables (and i mean alot) through the rails to the trunk.
I hope it'll all be worth it.
Thanks for all the help
