Output Wattage for Delco Factory Cassette deck??

[Looter]

My search for a new cassette deck is over, but I’m unsure of the factory wattage (getting new speakers), anyone know the specs?

I don't know for sure. But it's probably on the low side 10 or 15 x4.
I remember the first cd players we where getting in the early 90s where 25x4 and they where awesome compared to the factory decks.
