Thinking of adding a sub to my base audio, and possibly replacing the rear speakers. I think the base audio sounds good, very clear, good highs, mid-bass is decent, but little to no lower bass. I think a sub would really improve it, and others in the US have commented as such. I'm not handy with stuff like that, so I would want a good installer I can trust, preferably one who has worked on a Model S before. Anyone done an audio upgrade in the Toronto / Ottawa / Montreal areas? Thanks
I'm watching this thread with interest as well. I'm in Ottawa and would like to hear of good local installers.
