[QUOTE="Umbra, post: 8498823, member: 658055"] I don't know exactly which amp you're talking about, so give us a link and we can comment on it. You want an amp that does around 600W RMS at the impedance (measured in ohms) of your sub(s). If you're using one sub and it's an SVC sub (meaning single voice coil) then the load (what the amp "sees") will be just 2, 4, or whatever it's rated. If the one sub is DVC (dual voice coil) then it's a little trickier. DVC allows you to wire the voices coils together in either series or parallel, giving you expanded wiring options. For one 4 ohm DVC you can get 8 ohm or 2 ohm final. For 2 ohm you can get 4 or 1. If you're using multiple woofers you wire up each woofer, then wire them together.
