BMW3 Series E36 AMP Wiring?

Question

Today i bought a BMW 3 series e36 318i SE 4 door.

Tomorrow I'm hoping to install my amp and subs but I can't find any good guides with pics. I read about pushing the cables under the trim at the side and through a hole in the back seats but i cant find anything about the front end!

Can anyone provide any tips on the whole thing or point me in the direction of a good guide or forum post?

Thank you in advance

Answer 1

I drilled a hole thru the firewall of my E36 cause there wasn't a factory grommet with room for the power wire
