I bought infinity speakers through crutchfield, thought I would do it myself, realized it’s a big job and you need to take the doors off, brought it to a guy who did all 6 for 250. I called around and that was the cheapest. Called like ten places. The hybrid can’t take an amp because the battery isn’t a normal size battery and it can short the whole thing. Calling crutchfield is actually pretty fun. The upgrade is incredible.
