Power ratings (in & out) for FC 'Vert Amps?
 

I've searched using every combination of terms I could think of, but haven't found this yet. What are the power ratings- both of the signal they can take coming in & how much they output- for the amplifiers in an FC convertible? I'm myself interested in the particulars for an '88, but I imagine for other years would be useful for others if the specs are different. I'm working on rebuilding/restoring a 'vert and would like to maintain the functionality of the headrest speakers and their controls, but want to do some upgrading of the sound system. I've found a lot of good discussions about both ditching and re-using the stock amps- but I've never seen the power specs for them. Thanks!
