That amp will run the subs fine.. The fact that it runs 160W RMS x 2 into 2ohms is good. Most people really go overboard on amp/sub power. Unless you really want to crank it up to ear bleeding levels, you don't need a gajillion watts.
I run a crappy Jaycar 50wx4ch amp, bridging one channel for the sub, so it's putting out approx. 100w (not quite though), and that's more than enough for a little bit of doof-doof. It's only in a Magna, so who cares? lol
