I've had a 1000/1 feeding this sub about 500 watts since early April. I got the 1000/1 to get a W7, figured it is time to finally make the upgrade. Sub is in immaculate condition, I have treated it very well and even have a grill on it so cosmetically it is a 10/10. Sub has no problems, it is a 10/10 mechanically as well. 250 +shipping takes it. I'll throw in the grill for free. Get at me!
