It was 67 degrees when I went to the garage. Dang, having fun now.
The factory speakers in the El Camino are two little 3.5 inch speakers in the dash. The last time I had the windshield out for a replacement, about 15 years ago, I put in two "high quality" speakers with larger magnets, and more robust cone design. They were better, but still not great sound. The right side speaker has dried out from the sun and it is blown, so now really bad sound. To replace them means remove the windshield.
So there are aftermarket lower door panels that have speaker inserts. Easy fix right!
What a major pain. First they are black, so I will have to use the special plastic paint to make them burgundy. But it also means I need wires in the doors. So I have to take apart a lot of the interior to get to the plastic plug in the door area, drill a 5/8th hole abd run the wire and use a grommet to keep the water out in the rain. Same for the door itself. Then run the wires. The new panels are close the right size but need a lot of adjustments.
And "while I am in there" I will replace the carpeting that is worn out and faded. And while I am in there, I might as well replace the seatbelts made by a local company, Seat Belt Planet. So the seats have to come out to replace the carpet.
I am two days into a 10 day project it looks like. Golly what fun. In the end the interior will finally look right again, and I will have a far better sound system.
