Update:
Today I got another item off the checklist. Installed the stereo. Finding ways to run the speaker wires under the deck was challenging. I ended up using an inspection camera with a long wand, and poked around till I found a passage thru small openings between the deck and stringers. I pulled string thru them with the wand end, then used them as pulls for the wires.
I also removed the seats and put them in the shop for reupholstery. The sliding bases were corroded and cam out in pieces, so Ill have to order new bases. The pedestals are fine, just need cleaning.
The speaker cutouts were 5.3 inch and I didnt have a hole saw that size, so I had to make a circle jig and use a small router, worked out fine.
I coated all the connections with no-ox-id and wired the led speaker lights to the acc switch.
The wife didnt want the head unit way up in the ebox, because she would have a tough time reaching it, shes just a peanut at 5' nothing, so I gladly agreed, otherwise I would have to mess with it for her all the time. So I installed it on the console side in a weatherproof cover. I used 14g tinned ox free cable.
I wired it for 4 speakers, but the 6" didnt work in the rear due to the slight curves in the hull sides, so ill order 5" for the rears.
