Ok I'm about to do a complete change over on my 2 door LS. I've bought the speakers 6 3/4" Rockford Fosgate 3 way Speakers. But everything I've read on here says 6 1/2". Did I get some bad info, was told that the 6 3/4" would fit in the doors? Do I need some type of adaptors?

It's not necessarily bad information. 6.75" can fit in these trucks with little to no modifications depending upon exactly how the manufacturer built the frame. Though even when they fit it's not a perfect fit with the 6.75" or the 6.5". Your best bet is to build a custom mounting baffle. The stock plastic sucks anyway, robbing output and muddying the midrange. I can post pictures of how I did mine if you like.

 

That would be great thanks. I'm going to start working on doing the swap tomorrow.

 

No problem.

The factory plastic baffle isn't difficult to replace with a custom made one at all. It's attached to the door with only four rivets. It would be easy enough with a few nuts and bolts to reattach the factory baffle and keep the good custom made one if a person were to change trucks too. Now I made mine knowing that I would be installing some fairly decent woofers and running some fairly good power to them. That prompted me to overbuild mine compared to what most people would need to do. I also built mine to protrude slightly through the door card (plastic door panel) to improve response and imaging. Again not something anyone would HAVE to do so keep those things in mind when looking at these pictures.


Just FYI this is a 6.75" Polk RSD component set mounted to the plastic baffle.




Here's the baffle by itself.






If you notice the shape of the plastic in the picture of the factory baffle above you can see how I simply traced the outline of the factory baffle onto the wood in the picture below.




I used a router with a circle jig attachment to cut out the rings that make up the rest of the baffle. A jigsaw will work fine.






I used fiberglass resin and rubberized undercoating to seal the wood on my baffles. It must have worked pretty good as I actually (and very unfortunately) submerged this truck in several feet of water filling the inside of the truck to the bottom of the seats and never saw any swelling in the wood (MDF) I used to make the baffles. Even without any intentions on submerging them it's a good idea to seal them so that any moisture they may encounter (Rain, Humidity, etc.) does not affect them.






And finally I mounted them to the door with 3/8" bolts. Again, overkill, but I wanted to be sure that they couldn't have been more solidly mounted.











Hope this helps.

 

Not sure I can do that with the equipment that I have. I have some scrape MDF that maybe just big enough to try and make a set.

 

A jigsaw and a drill should be all you need, especially if you don't plan on protruding through the door card like I did. Like I said, mine are an example but may not be the best way to proceed for everyone.

 

How deep of a inset did you do on the top piece? What type of glue did you use to attach them before you coated?

 

It was a 1/4" deep recess on the top ring if I'm remembering correctly. It's been almost five years since I built them. I do know for certain that I used Titebond II wood glue, but any wood glue would do just fine.

 

OK Thanks. About to go out and Tackle the rear speakers first I figure they are going to take the longest to do.

 

Well Ok The Back Speakers are done Tried to make the MDF Bracket.....Not Gonna happen. So I went ahead and installed the speakers to the original baffles. Worked ok. Then I pulled the dash speakers out expecting 4X6 Speakers. well they were only tweaters. I bought the Meata GM speaker Connects so I wouldn't have to do a bunch of soldering. Well that didn't workout either. But the connection on the tweaters are different that the others Am I gonna have to cut the wires at the tweaters in order to install the 4X6 speakers that I bought?????? HELP!!!!!!
