Need information on installing an amp/sub

Daft · 06-21-2010, 08:40 PM

I'm sure this topic exists already but I couldn't find anything on the search.
I would like to add an external amp/sub combo to put in my trunk. So what I need is to tap into the existing stock system's line out (speaker level output is fine) and the +12v switch. What's the best way to tap into these sources? My car is a 2011 E92 M3. I'd like to avoid ripping out the dash if possible which I had to do with my E46.

PM Technic, he's got exactly what you need.

If you have the standard HiFi system, everything you stated can be tapped from the stock amp located in the trunk.

Kaigoss, can you tell me who Technic is? I'm new to this place, and I'm also trying to install an external amp/subwoofer.

Just send a private message to Technic. He's a very helpful forum member and happens to sell a harness that will allow you to do exactly what you are asking about.

What system do you have in your M3?

I have the standard sound system in the M3 with the Navigation system installed- basically I do not have the premium/enhanced audio system upgrade. I have an a Audiobahn subwoofer and 1200w amp that I'd like to try and install in the car if I can.

I do not offer any add-on sub harness for the HiFi system; I will be offereing for sale a HiFi harness soon to replace the OEM amp completely, though.

Do you know where I can find a guide on how to wire the sub into the system of the car?
