I have installed or modded stereos on pretty much every vehicle or bike I have owned since 1976. It has been my experience on a lot of the older vehicles, it's just better to run new wires, (especially speaker wires). It's not really that difficult and when you run new wires, you KNOW where your connections are, instead of relying on modular connectors that may be heavily oxidized/corroded.
Case in point, I recently had 2 different occasions where I had to re-take the front shelter off completely on my GL1500 when I relied on the original plugs.
One of the plugs, I had salvaged from my old GL1200 because it gave me the proper number of conductors. The plug worked fine for about 2 months, and then it didn't.
So, since you seem to be handy and also electronically knowledgeable, do yourself a favor and run new speaker wires. On my GL1500, I added a new fuse panel fed from a 40Amp relay, triggered by voltage from the auxiliary terminals on the bike fuse box. It works great and I don't have to worry about overloading the bikes original 1993 wiring. I tend to over build everything I do... I have six gauge wire running to my fuse panel on the power connections and also from my new 95Amp Lactrical alternator that I installed.
I have lots of spare power for any new add-ons, (like my heated grips, and seat heaters on bike and side car).
Let me encourage you to plan ahead and think past this one project.
Where do you want to go with this bike? Do you want to do cross-country with all the bells and whistles or just have a go-to-work bike?
When I had my 1986 GL1200 I did a lot of custom stuff to that bike, including making rear 6 1/2" speaker pods out of Sintra. That was a lot of fun.
Best wishes in your project.
