I just installed Infinity 6 3/4's in the front doors replacing the factory speakers and after hearing them would like to do the same in the rear. I have read many threads stating that the same 6 3/4's will also fit in the rear. I searched up and down to find install threads on this subject and found the one I needed, to bad the link to his write up no longer works. :thumbs:

 

My question is, does anyone sell an adapter for the ext cab doors or is this strictly a fab yourself type of deal. If I must fab adapters myself can you all give me some hints, pictures of install, etc, to help me on my way.

 

Much appreciated!

I searched for adapters for the rears but never came across any when I upgraded my system. I ended up not using the rears anyway so it didnt matter much.

 

This guy went with 4x6s in the rear but he really didnt do anything to seal the front of the speaker from there rear. Dont think you will get much bass from it but then again there probably wasn't much to be had in the first place being that they are so small.

This guys made a bracket for his fronts out of MDF but doing it for the rears would be a similar concept:

Good luck.

You can make plates out of wood or....

What I did for the front and rear, was cut the factory speaker out of the plastic bracket/speaker assembly with a drimel tool. You have to do alot of cutting and trimming, but it works. So your pretty much destroying your factory speakers to make your own brackets for your new speakers. If you do that, theres no turning back. I have pics but will have to dig them up, so PM me if you want me to post em.

 

I used Infinity Kappa 62.9i speakers in the front and rear. If these are what you are using, STOP NOW. You will need an amp to push all 4 speakers, the factory radio won't do it alone. Well, it will, but will sound like total crap and you will end up with your stereo adjusted to only play the front 2 speakers untill you buy an amp.

 

So think about it before you do as I did. If you end up mounting the rears speakers some other way and want to get rid of your factory rears, let me know please.

They do not make an adapter for the rear on the extended cabs you will have to make them yourself. I used a 1/4" thick piece of ABS plastic which worked great.

      2027 GMC Sierra: Official Discussion

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
