I have 2 12inch W3D2's I have them wired up to a JBL600.1
it absloutely hammers when i want it to and sounds great all the time. I entered it in a sound off and i hit 143.3 without maxing it out. The JBL amps is a good choice, they are a class D amp so they are very efficient, not drawing too much power.
The amps are very reliable, me and my friends all have them, among us we have 3 JBL600.1 and 2 JBL180.2 and none of us have had any problems
