E30 Zone

Hi my fellow zoners. I have a 1990 316i e30 5door model. I am at the moment thinking of buying some pioneer speakers for the front. The only thing is I need to know how to fit them because the location of the original speakers are right behind the lever for the bonnet and the drivers side one is in the same location. Any fitting advice would be much appreciated, or any video tutorials would be a godsend. Thanks for reading.

Thank you.
