My SS is cut for speakers. I did'nt do it. It did'nt weaken it much. I did put some dynamat there to help with vibration though. Just put them where you like them.

The 67 I'm working on now, was never cut, and I've decided not to do it. I'm just going to install quality speakers in the factory locations, and leave it.

 

One of my friends was parting out a 73 Nova. I cut out the whole package tray. It already had two holes for 6x9's. I then cut holes in my 66 tray large enough to clear the 6x9 holes and then welded them together.

In my 72 my tray was hacked up but I didn't want to see the speakers, so I mounted them under the metal so the package tray sits flush on top. I need to make the package tray more permeable as it muffles a little, but it works fine, as they are the only speakers that I have in it and can hear the music fine.

 

That's what I did, but I used the factory style speaker grilles, so they fit nice and flush

 

cutting the factory ribs for 6x9 speakers will not weaken the tray. as posted earlier, mounting the speakers below the tray will make them less obvious.

 

yeah, somebody hacked the whole package tray in my 70 and we were thinking about welding some tin in it or something so it doesn't look so bad and I can mount some speakers.....any suggestions?

 

Here's how mine were done on my 66.

 

Now thats quality...must be an arm and a leg

 

You could also do like I did for a customer's Chevelle:

On this one I used the original deck material as a template and cut a new one out of thin masonite. After marking where the oval holes would be I cut out the material. I then took some old 6x9 mesh metal grills and flattened them and placed them on the topside of the deck and marked around the outside edge. I then took my 3" angle sander with about a 36 grit wheel and thinned the masonite from that mark inward towards the cutout oval hole. I went down far enough to where when the grill sat in the recessed area it was flush with the rest of the topside of the new rear deck. I then took some liquid nail and glued the grills onto the masonite. After it dried a ran the sander over the topside to smooth it out and then took some automotive speaker cloth that was UV treated and stretched it over the whole rear deck. The material is somewhat thin and you may want to shoot some black paint on the topside so it doesn't show through. I also just glued on the edges and backside so I could work out any wrinkles in the cloth and not have to worry about the glue bleeding through.
Since the factory rear deck normally had a flap on the front edge I took some subwoofer carpet and stapled it to the topside of the deck and then folded it back over itself to where I had a flap to glue to the metal behind the rear seat.

Total cost on mine was a couple of bucks for the spray glue and wood, maybe $20.00 for the grill cloth and a few bucks for the carpet to make a flap. Timewise maybe 2 hours ?.

I bought the 'deluxe package tray', which has holes through the cardboard for the sound to go through. The whole top of the package tray is covered with a screen:

I used dual coil speakers from custom autosound. They were supposed to be 'bolt up and go,' but as you know, it is never that way:

The speakers sound decent, but I've never been much of an audiophile...
