I want to get the Cadence Z8000 for my CDT Components and it says the Freq Response is between 10hz-40khz and my other amp for subs would be the Cadence Q4000 and that freq response is bettern 20hz-30khz. That hz for the subs is low enough right? Thanks

Yeah, I'm pretty sure you don't want your subs playing lower than 20 hz. In fact, there probably aren't many songs that actually achieve a note that plays below 20hz. I could be wrong, but I'm pretty sure 20 is as low as you want to go.

Lowest humans can hear is 20hz, so it doesn't matter what so ever.
