Cadence SQA-4 or MB Quart NAU-460?

[sc_beerbarge 10+ year member]

Looking for a cheap 4 channel amp for the boat. So far I have it narrowed down between the Cadence SQA-4 and MB Quart NAU-460. I'm open to both or other reccomendations. The amp will power (2) 6x9s and (2) 6 1/2 speakers.

Thanks,

SCBB
