jl 13w7 wiring

I just got a jl 13w7 for a screaming deal and have a good 'ol amp the memphis 16pr1.1000. the amp runs 1 ohm stable at 1000, but the sub wired down in parallel goes to .667 or something crazy like that. I really don't want to spend another 500 bucks for a jl 1000/1v2. will my amp work? or is...
