So there are 2 versions of the kicker cvr12s, the 2ohm and 4 ohm. my amp is a 2-channel and If Each sub is 4 ohm the amp supplies 300w per sub, 2 ohm and it is 450w per sub. my question is this, witch should i get. 2 2ohm or 2 4 ohm subs. And how should i wire them? Keep in mind i have to end up...
