Hi all,

Planning to wire a subwoofer into a 2013 E250 using the rear speakers to acquire the audio signal.

Running the stock standard NTG audio system - anyone know what colours the rear speaker wires are and where to access them (preferrably via the trunk)?

Wiring diagram would be particularly helpful if available!

Thanks

Hi. How did you get on?

I’m myself on the same page. E220 bluetec, basic audio set up with no speakers in the rear deck. So I need to tap into rear door speaker to take to the aftermarket amp but this is where I’m confused. Rear doors both have a mid/woofer driver and a tweeter. The tweeters both have a separate connection going to them but thw mids/woofers have a connection with 4 purple wires going into them. Now I understand that these are 2 negatives and 2 positives, 1 for the highs for mid frequency and 1 low for lower frequency. The problem is I don’t know how to figure out which is which?

any help would be highly appreciated.

Thank you so much for sharing this information.
Very much appreciated after spending hours trying to find what the colours were.

Hello dear member, can you get a diagram or list with the colors of the audio cables for a 2016 Mercedes W213. normal sound system. I am very grateful

Dear Retna, many thanks for the diagram.

Hey everyone! Looking for some help and not a technical guy at all!

I would like to install two amplifiers into my car, one for the bass and other for mids.

I had a few questions;

1. Some people talk about connecting the line-out-converter to the rear speakers, which saves removing the dashboard. Can this be done and if so, how and where are these wires?



2. I noticed there are two wires for Bass Speakers (H4/17 and H4/19), is there any in particular I should tap into?

3. For the mids, which one should I tap into?

I have attached the user manual for the LOC, if that helps see what I got?

the nicer systems on US W212 cars use an amplifier in the trunk area that has an optical MOST bus input. some have 2 amps, one for the main speakers and one just for the sub, later ones (maybe just 2016?) have a single amp that runs the mains and the sub. you can get MOST adapters that will decode the digital audio to 'line' levels you can feed your own amplifier.

Do you have a subwoofer speaker in the rear that you can tap into to boost it

the factory amps including the sub amplifier are quite heavily equalized to make the factory speakers sound better playing into the shape of the car..
