Wiring for SUB.

[e30kid6]

Hello,
Right I was planning on wiring up my sub yesterday but I soon realised that I couldn't find any clear sort of hole at the rear of the engine bay where I could stick a couple of wires through to my battery. In my previous cars the battery has been on the passenger side, so i'm not too sure where to look. I've seen where the main loom goes through, but I can't see that being any help because you cant get to it from the inside of the car. Any help please?

It's easily accessible behind the glovebox, and is provided with cut out sections for extra wiring.
Why can't you access it?

hmmm this loom i was looking at went in behind the battery and into the dash behind the clocks, I couldnt get to that. I didn't manage to see anything behind the glove box, but then again I didn't think there would be anything there

That's the engine loom going to the ECU - such is the design of the E30 that the engineers specified that the ECU should be inside the cabin, away from the elements, unlike on later models and other makes. There's no provision for any other wires to go through where that goes though.
The body loom passes through where I said, through a large grommet, around 3 1/2" across, that has cut out sections for additional wiring.

Okay thanks a bunch. I'll have another go tonight.

Thanks for that, found it pretty much straight away. Wish I looked there first time round!
