I dont buy into people down talking cheap products. I give everything a fair chance. I purchased 2 of these subs hooked up to a Boss CX3500.1. When i was running them @ 4 ohms 600 watts each they performed pretty well, but sounded like 10's. Werent very loud. I wired them down to 1 ohm 900 watts each (what they claim they are rated at) and they bumped, but within 2 hours they started smoking and blew the voice coils. Boss amps arent bad, but the subs are EXTREMELY OVERRATED. Do not waste your money on them unless youre only gonna run 600 watts max to them.

My friend had 2 of them pushing exat 900 watt rms to each sub they blow right up after hucking them out after a half hour not even pushing them. Do not get.
