Rear Speakers

I own a 1997 Z3 with factory in-trunk amp. I want to install rear speakers. Are they prewired and if so, where are the wire hookups located? I was also thinking about splicing into wires off the amp. According to my wiring diagrams (Bentley) there are wires coming out for rear speakers. I found them. Any advise?

It depends on whether you have the Harman Kardon system or not. Also, there's not much depth for rear speakers; even the original ones had to be pretty small, so they can't do much. And many fuel tanks have been damaged while attempting to drill or drive screws back there. I have the original speakers in mine and they have been disconnected for years. Instead, I have a really good set of 6.5" kick-panel speakers with component tweeters in the doors. There is a lot more room to work in the front.

I thought you said you found them: "According to my wiring diagrams (Bentley) there are wires coming out for rear speakers. I found them. Any advise?"


If you have the HK system, the two right rear speaker wires are blue and brown and the two left rear speaker wires are yellow and brown. If you don't have the HK system, the two right rear wires are blue/purple and blue/gray and the two left rear speakers are blue/black and yellow/brown. They are connected to the amp at the J2 plug (the big one). The run along the front of the trunk and enter the soft-top boot via a grommet on the driver's side. Then they pass through the boot next to the driver's roll hoop and run behind the carpet to the speakers.

I just ordered rear speaker replacements from BavSound, claiming to be a good upgrade over stock speakers. I will post a review once received and installed.

I recently installed a rear pair in my '01 Z3 3.0i (HK system). I am not impressed for the price of admission. I am intending to return mine. BTW, they are not their newest speaker design.
