Has anyone ran power cable through the bulkhead on b5 for an amp.
 

I'm looking to put an amp in the boot to run a sub to get a bit of bass.*
I'm struggling to find somewhere to bring the 12v power cable from the battery to the boot. If anyone has done this can you give me any help or tips.

theres a bunco of wires under the dash near the steering column that go through the firewall just look up there and find a way in. then just run it to the boot under th carpet.

Search for "amp power wiring" or something similar. You'll find all the info you need.
