Today's mini project - the rear parcel shelf speakers.
Once again, sincere thanks to Robah (Rob) for his generosity by giving me a pair of original GM speaker pods. I wanted to fit these to make the car a little more authentic and a little less 'in your face' - which is how it felt with the previously fitted enormous Pioneer ones.
Rob had already told me that he thought that the original speakers might be a little tired, so we investigated. The top covers are held in place with snap fixings and a simple turn of a screwdriver gets you inside:
As you can see, Rob was right:
After looking at a few speaker reviews, these guys seem to fair pretty well, and at £35 a pair delivered, they seemed good value too:
As luck would have it, they were a perfect fit in the existing pod and I didn't even have to drill any new retaining holes:
I was even able to reuse the GM mini wiring loom too - it couldnt have been any easier quite frankly:
Here you can see the internal connections and these are thoughtfully recessed on the back too:
Upon removing the parcel shelf itself, I was reminded that it was warped in a couple of areas on the edge nearest the glass, presumably cased by damp/water at some point when the car was standing for 18-20 years...
I will come back to that later...
Position the speaker pods (I put might so that they would cover the existing holes and cover one strange random hole...) and mark through - I used a wooden skewer I found in the kitchen draw lol. Then drill your holes to suit:
I decided that as the speaker pods have little weight they only really needed a small retaining method, so opted for short screws through the parcel shelf. The 2 x screw holes in the pods themselves are masked by the top covers when fitted. Here you can see the screws that I chose and how far they stick through:
Just to make sure that they would be scratching around on the metal of the parcel shelf underneath, I chose to glue some rubber grommets over the exposed screw threads:
With the speakers now attached to the shelf, I decided to tackle the warped edge. Assuming that water had caused it to warp, I thought that maybe water might help me solve the problem too?
I therefore may the back of the shelf quite damp and then clamped a length of electrical conduit along using whatever clamps I could quickly lay my hands on:
We will see what we have once that has dried out and then I plan to use some cleaner on the facing surface of parcel shelf itself to try to revive it a little.
As I didn't want to have to speaker cable running directly under the rear seat, then running under the parcel shelf board, I followed to main wiring loom into the boot space, then drilled holes into the Steel of the parcel shelf. These holes correspond exactly with the holes in the parcel shelf board. Then rubber grommets were used and the ends of the cables prepared:
Once the board has dried out, I will refit that and make the final speaker connections.
I hope that all helps somebody else at some point?
