So look at my postings above and you'll see Alpine has different recommendations for factory speakers v. replacing with the ones in the PWS24 kit. Interested in what you come up with. I'm getting pretty happy with the sound at this point.I just pulled the owner's manual on the KTP-445U.
It appears that Alpine suggests the HPF to be set at 60hz:
I might fiddle with this tonight and try out the 80hz filter, re-blend the sub, and report back.
