47-54 Cab Corner 6x9 Speaker Brackets

Although not 73-87 related, I have decided to fabricate and sell 47-54 cab corner 6x9 speaker brackets for our older GM brothers.  Just like the 73-87 cab corner 6x9 speaker brackets, these brackets provide GM truck owners with the opportunity to upgrade the stereo system in their truck by allowing them to place larger, more modern and better sounding speakers in the cab corners.  Made of heavy 16 ga steel, laser cut and bent, there brackets fit perfectly into the cab corner and are very easy to install using regular hand tools.  Kit consist of L & R speaker brackets, L & R adjustable floor mounting brackets, mounting hardware, and detailed instructions. These come bare steel, and will need typical metal prep and paint prior to installation.  Brackets can be painted, powder-coated, upholstered...it's entirely up to you!  For those wanting to install component speakers, these can also be ordered with no oval speaker openings as well.

**These brackets will only work if the stock in-cab gas tank has been relocated**

Made in the USA!

"I was lucky enough to get my hands on a set of brackets for my 53 3100. These things fit wonderfully and are nicely built. I didn't install them personally, but the guys at the shop were thrilled with the parts - thick steel and easy to work with. They really are a custom fit for these cabs. I didn't want to cut holes in my doors or install kick panels for speakers, so these brackets are exactly what I was needing. Highly recommend these if anyone else is in the same situation. Thanks, Jeff!"
