Your IX1000.1 is going to be okay with the CVX woofer. I like to supply a little more power than the woofer is rated for; this will be fine unless you go heavily distortion-clippin the amp.
Tried to call Kicker technical support and ask them but it was after 5pm. I was wanting to run a CompVX 12 with a IX1000.1. I know the specs on the CompVX12 is 750rms, stupid question is, can I run this setup? Are the CompVX beefy enough to be run by the IX1000?
