Volvo amp specs

[Hendri Verveda]

Hi,

Can anyone tell me what the specs are of the original volvo amp with type
number 9496557?
Same question for type number 3533876

I have a SC-901 and am looking for the original 4x100W amp for this. What is
the type number of this amp?

I have looked all over the internet, but no success.

Kind regards,
