How to Add Modern Speaker Technology to Your Classic Chevy Truck

Classic Chevy truck speakers are usually the weakest part of the truck. Classic trucks have plenty to offer in engine feel and build quality, but the audio systems are often lacking. Our cab corner speaker brackets let you install a proper pair of 6×9 or 6.5″ speakers in a 1973-1987 or 1947-1954 Chevy truck without cutting the cab.

Typically, these classic Chevy trucks include dash speakers only. They are not very powerful, and the sound quality is poor. Installing LS Fab Speaker Brackets lets you upgrade your audio system with more speakers and modern technology, easily and affordably.

Placing and installing classic Chevy truck speakers

Inside the cab, the corners contain a lot of wasted space. In most cases, that is the perfect place for a new set of 6×9 or 6.5″ speakers. Install a pair of LS Fabrication Speaker Brackets with the included hardware.

We offer brackets that house 6×9 or 6.5-inch speakers, which is a large step up from built-in dash speakers. First, test the fit of your exact speakers before you paint or upholster the brackets. That way you know the speaker holes work with your specific speaker. If they’re slightly small, you may need to trim the hole a little.

Once your speakers fit, align the brackets in the rear cab corner area to determine the exact fit and placement. Check the position with the seat all the way back. Then use the included hardware to attach them to the floor. You can secure the top with screws, or weld it if you prefer. Once mounted, connect the speakers to the brackets and wire them through to the correct connections. Consult your speakers’ installation manual if needed.

Will these classic Chevy truck speakers brackets fit yours?

We designed our Speaker Brackets to fit properly. They are 18-gauge raw steel, laser cut for a precision fit, and shaped for the cab corner of a specific era of Chevy truck. These brackets fit the 47-54 and 73-87 Chevy pickups, so a different year or era won’t fit correctly. However, we’re always working to expand the product line, so check back for brackets for other eras.

If you’d like to confirm fitment before purchase, the product listing shows the bracket measurements and hole sizes, so you can compare them against your specific speakers.

Finish options: paint, carpet or vinyl

Our 47-54 speaker brackets come in a smooth or bead-rolled design option for a bit of customization and flair. Our later-model 73-87 brackets come in smooth only, as they’re much smaller. Either way, you can spray-paint, carpet, or wrap them in vinyl so they look factory-installed.

Both years are available for 6×9 or 6.5-inch speakers, so you can buy the mounting brackets that fit your speakers properly. Most go with the standard 6×9, though 6.5-inch is available too.

What tools does the job need?

All bracket kits include the hardware needed to install the Speaker Brackets, but you’ll provide your own tools for installing the brackets and speakers. Typically that means a screwdriver, utility knife, socket wrench, and electric drill at minimum. Some customers prefer to weld them in position if they’re at that stage of their build. However, our kit includes all the hardware, so welding isn’t required.

Revamp Your Classic Truck

Good audio matters. Not knowing how to mount speakers properly is one of the biggest reasons classic Chevy owners haven’t upgraded their sound system. These speaker brackets provide support and stability in the unused space of the truck’s cab corner. They are simple to install, made of high-quality materials, and affordable. If you’re ready to give your classic truck a modern audio revamp, we encourage you to check out a set today.

We cut speaker brackets to the factory cab corner, so the fit depends on your generation. We now make them for the 47-54, 55-59, 67-72 and 73-87 cabs. Most owners pair the brackets with a modern head unit, and the Crutchfield fit guides are a useful cross-check for speaker depth before you order.
