Hey!
Recently bought my first MB, an E-class 2015 model.
I've got a couple of questions regarding installation of subwoofer and amp that I hope you guys can help me with:
1. Can I connect my amp from the secondary battery in the trunk? (Is it strong enough etc)
2. My amp has a "high" input, and I was thinking I could go with an High-Low converter. Would I just tap into +/- on the rear speakers?
3. Where should I connect my remote wire? One of the fuses? Which one?
4. Anything else I need to worry about regarding the original audio system? I just want to add a subwoofer to the stock system.
5. Off topic, but: There's not a way to get keyless start on this model, right? (

Thinking of just the start button instead of having to put the key in the ignition.
I've tried reading the posts already made in the forum, and i'm totally new to this, so excuse my questions and confusion.
I've been installing car stereo equipment in my own and friends cars for probably 25 years. Look up my sub install thread for W212, that's all you need to know.
1) I would not, run the proper gauge power wire for your amp needs to the main batter, with a fuse or breaker
2) always sounds like garbage. See my thread on how to tap the factory pre-amp signal.
3) I think i used the cigarette lighter, but forgot now
4) 2x12" will far overpower the rest of the stock system. It's ridiculous. I thought people stopped doing that much speaker in the 90s.
5) If your car didn't come with Keyless Go option, it's nearly impossible or at least cost prohibitive to add it. Many components involved, all over the vehicle, not to mention someone who really knows how to us a Mercedes STAR computer to active the addition of those parts.
Just completed my install on adding a subwoofer and amp. I ran the power and ground from my Alpine to the battery in the trunk. Next the remote and signal came from the factory sub under the decklid in the trunk. Since the factory amp only has one signal, I used a female RCA to two males. Most amps these days need two signals left and right. Also I applied Dynamat to most the trunk area, especially the spare tire. So far the sound is great and I have tight punchy bass. JL recommended thirty hours for break in period. I want to thank RNBRAD and jonUFO2 for helping me with this install.
Setup
1. Alpine mrv500 mono amp
2. JL AUDIO CS110LG-TW3 SUB BOX
3. ROCKFORD FOSGATE 8G wiring kit
4.Y adaptor 2 RCA (male) to 1 RCA (female)
5. IEC 18 awg wire (bare wires) with RCA male one wire needed
6. 3-4 T tap used on factory amp
