these people are nuts, those subs mentioned above are all way to big for this amp.

get a pair of JL audio 10w04 (get the 4 ohm version) wire 'em down to 2 ohms. they handle roughly 150 watts peak. they have a 1.38" voice coil. they aren't going to pound like the IDQs (but they aren't as expensive, and you really need big power for the IDs). But the JL 10's would be perfect for that amp. 10w04 is the way to go.
