Thanks. For some reason the Hankooks did not appear to be as wide as the Falkens. I ordered them in the same size as the TGs and Falkens (285/65/18), but they HKs did not look as good once mounted. I think is because of the tire walls or tread pattern. So the problem was the looks, and not the performance (just used them for 1 day).
The Infinity set-up was purchased on Ebay. Paid $119 shipped (compare to Best Buy $299). Only thing missing were the mounting brackets, which are still on backorder from Infinity ($15). The subwoofer is strapped to my back seat in the mean time.
For installation, a local shop charged me $75 for the wiring and hook up. Not too bad as I tend to blow some fuses and burn wires.
Regards
