Adding Carver 4060 into all Alpine system

I just scored a mint 4060 and would like to add it to my already crowded system in my Nissan Frontier. My system is:

CDA-9833
MRV-T420'S (Two run mono) MoMo MMC-6500 components
MRD-501 running one Polk MoMo m-104 in a bandpass enclosure.

Any thoughts? My head unit is capable of running an active crossover to
the amps without using the Polk crossovers. (The head unit is programable using the Alpine ipersonalize system)
