I was actually looking at one of those myself if they will make one for 10s instead of 12s to replace that big bulky square box in my trunk right now...If I get one, I will get it painted yellow to match the car, but that does seem like a lot to pay for a speaker box...
^ BTW. I have two 10" Alpine Type E's and a 1000W Kenwood class D Mono Amp...I just bought the amp this past weekend, it's incredible compared to the Sony Xplod 2-channel that I had in there before...
