talk to me.
I just installed the speakers and used the factory wiring. BMW used 16AWG for the woofers and 14AWG for the mids and tweets. This is more than sufficient. The wire is also much better quality than anything you would buy in the aftermarket. Its also nice to have all the wires colour coded for reference.
