Wattage and impedance of GPWS aural warning speaker

Postby JamesC » 29 Oct 2020, 23:18

Hi folks!
I purchased a non-airworthy GPWS aural warning assembly recently, and want to repurpose it to use for music as a souvenir/showpiece of sorts.
It's part number 69-37336-8 pulled from a 734 – after checking several versions of the AMM I can't find any information for what type of amplifier (watts and ohms) this speaker is designed to handle. The closest info I could get was that the signal passes through the REU, but no further info beyond that.
Any further info for this oddball question would be greatly appreciated!

I have a lo of similar souvenirs from different dismantled plane in a garage of my Czech real estate here, when I get back home later today I will let you know about a amplifier type you need.
