I would like to add that there is a BIG markup in car audio equipment. Retailers, especially the bigger ones have a LOT of dicker room. A 100% to 200% markup is not unusual, and on some some "cheap" brands even more. JL is one of the better brands out there, in my opinion, and like their speakers and subs. My 450/4 has been to the shop once, part of it shorted out, but it kept working! We are beginning to see a lot of Chinese knock offs, beware. The class A and A/B amps cost more, but in a motor vehicle a 1% distortion properly would not be noticed traveling down the road.
I got the steps at a local shop, they are ICI's. The chrome on them are not the best, and the tubes are not the thickest, but the rear step is really nice. Yep, 285's. They fit great, ride nice, great off road, and carry a LOAD. I've had too big (and meaty) of tires in the past, "TIRED" of the problems they cause.
