Line Output Converter - Ground question

[ludvigandersson]

Hello all,

I recently purchased a line output converter from bestbuy (https://www.bestbuy.com/site/metra-two-channel-line-output-converter-black/1265702.p?skuId=1265702) and it has the two left and right speaker wires that i have connected to my rear sub wires in my 2016 Golf GTI. The LOC has two ground wires coming from it, do you know if it is necessary to run either or both of these to ground? Any information helps! Thanks!

No it is not necessary to connect those unless it is making a sound through the speakers.
