Hooking up old Bose head unit and old Bose woofer to brand new Bose outdoor speakers

[Jynx228]

We recently dug up our old Bose sound system that hasn't been used in 6+ years..

It only has a head unit and a woofer, but they both work.

So we bought brand new Bose outdoor speakers, and called Boss support to see what we had to do.

They told us that we needed to buy an expensive amplifier.

However, the woofer has an amplifier inside of it, so we figured that we could somehow use the woofer as an amplifier.

How would we do that?
