I have 2 jl w7 13.5's and 2 1000/1 amps sitting in my garage, I used one of the 1000/1's to run my RE xxx 15. the bass the amps produce are good clean power, the amps do get a little warm, but if you take and add about 1/2 an inch under the mounting feet to raise the amps off the board, it helps dramatically, at the end of the day, I enjoy the amount of bass the w7's produce, the power is insane, the response is clean and punchy and the low end is totally there almost as deep as my xxx 15. The subs don't need the big huge box that alot of other drivers that are in the same power and size. and for the equipment with out thoughts on price, is amazing, clean, powerful, and does just about everything you can ask of the equipment for what it is.
