I have a Model 3 SR+ and want to add an amp and subwoofer (similar to the premium models). It looks like the cost of the equipment won't be too bad, but the labor may be the issue. There's no box and no harness back there. I'm also still not sure where they would connect the amp. Some posts say tap a 12V battery under the rear seat, some say use the 12V battery in the frunk, and others are recommending tapping into the speakers.
Is this a pretty standard install for a car stereo company? I'd like to just do a little research, pick a couple of companies from Yelp, and get some price quotes. I'm in San Diego. For most cars this is a very, very standard thing to do I would think. But for a Tesla Model 3 SR+ with no wiring and no existing sub in the trunk, then this might be a lot more complicated? I read another post saying this could be about 4 days of labor.
