Jeep GC 1997 which factory amplifier?

My Jeep GC 1997 factory amplifier is blown I would like to replace it
with the minimum effort possible bue I cannot guess which brand and
model is: does anybody know it?
BTW in italy is seems impossible to find an used one :-(

 

Lrkwz did pass the time by typing:

the ramjw charter kinda frowns on crossposting, but since your here.

According to
http://www.carstereohelp.com/jeep.htm
it's an Infinity amp.
This might help http://www.wjjeeps.com/audioupgrade.htm

eBay is a possible source, but it might be cheaper to get a new
head unit that doesn't need the amplifier.

Replaced my stereo about one month after the ZJ was delivered.
