In regards to the price, I actually got it on eBay for $119 so with the shipping less than $150 overall! I don't think its waterproof, but the all metal cabinet and poly cone should take a splash or a few raindrops. I'll try to get a pic of the install up. This thing isn't so much a thump thump sub, its not menat to be, more like a high fidelity home stereo sound, again with a good soundbar and its 120 w amp, its more like home theater sound in the car (jeep) and I have a soft top, really, I couldn't be more pleased and it takes up no space! I found the best position for it by folding the seat first and then placing it behind the folded seat so it doesn't catch under the front of the seat when folded. Still fits under with the seat upright. BTW, I also recommend the Sony Xplod or any other head unit with a wireless remote! Its addicting, you control everything, EQ, sub level, fader all with one finger while driving, don't know how I lived without one! Only problem is when you hit a bump and it falls on the floor!
