Hi,

I have a fiat 500L. I would like to add the oem subwoofer that comes with the beats system. I been trying to find the extra wire for the subwoofer at the trunk of the car. Does anyone have any idea if that extra wire it's included on the trunk of the car? If so, where it's located?

Thanks, in advance.

Where did you buy your sub? I need one too[emoji134]*

I've just fitted a subwoofer, an 8" active juice A8 subwoofer, great sounding, and not overpowering, used it with the standard stereo , and didnt even change the door speakers, very happy with it, especially as the standard stereo has an equaliser that does the job.
I have a non beats MPW, but I did look for a redundant (beats) subwoofer harness/cable under the carpet or hiding under the side plastic trims, but couldnt find anything.
As a basic non ideal, but satisfactory method, I had to solder/connect the speaker signal cables to the uconnect stereo rear speaker cables, and bring the cable under the carpet to the sub.
I took power from the rear 12v accessory socket to power the sub, and I cant hear any hum, so very, very pleased with the result...
