[QUOTE="Umbra, post: 8507111, member: 658055"] You can't just pick an impedance on the fly. The final impedance (what the amp "sees") is based on how many subs you have, how many voice coils those subs have, what the impedance of those coils is, and how you wire them (both at each sub and how you wire the subs to one another). You can read up on subject and the physics and math behind it, but you're better off using a wiring calculator to see these values in action and how to wire them: [URL="http://www.rockfordfosgate.com/support/wiringwizard.aspx"]http://www.rockfordfosgate.com/support/wiringwizard.aspx[/URL] If the amp is .5 ohm stable (I don't know if it is - though it looks like people have been doing it anyway) you could get two dual 2 ohm woofers, wire each sub's voice coils in parallel to get 1 ohm, then wire the subs together to get .5 ohm final at the amp (as recommend above). You could also do dual 4s to get 1 ohm final, which is definitely supported on that amp, albeit it with a bit less output. [/QUOTE]
