Bring modern sound and lighting into your classic Squarebody with our bolt-on lower door speaker panels — designed specifically for 1973–1991 Chevy & GMC pickups, K5 Blazers, Jimmys, and Suburbans.

No more hacking up your doors — these panels give you a clean, factory-plus way to run 6.5" speakers without fighting the power-window motor or cutting the door apart.


🔧 Built to Perform

Every set is built by hand here at Blazin’ Biddles Offroad in Northern California, using premium materials and a design that’s been refined over months of testing and fitment.

Standard Features on Every Set:

  • Laser-cut aluminum back panels for strength and precision
  • Sealed PETG speaker chambers for tight, clean audio performance
  • Integrated LED backlighting, pre-wired with quick-disconnect harness
  • Pre-cut sound deadener and acoustic foam for vibration control
  • Quick-connect wiring harness with grommet for clean install
  • Includes all mounting hardware and single wire pass-through
  • Designed for 6.5” coaxials like the DC Audio DC-65CX

These aren’t just for looks — they’re engineered to sound and perform like modern door audio should.


🎨 Customize Your Setup

Every truck is different, and so is every build. Choose from multiple finish and grille options to match your style:

  • Speaker Grille Options: K5, Silverado, Custom Deluxe, or Plain Bar
  • Color Options: Raw Black or Factory-Color-Matched Plastics
  • Audio Add-On: Optional DC Audio 6.5” speakers

Each set is assembled to order — your panels, your finish, your build.

Pre-Order Refund & Cancellation Policy

🔹 Refunds Before Production Begins

If you cancel your pre-order within 7 days of placing it, you’ll receive a full refund — no questions asked.

After 7 days, materials and production costs are already being allocated for your order, so cancellations will be subject to a 15% restocking and processing fee.


🔹 Refunds During Production

Once production has started on your panels (custom color, emblem, or lighting options ordered), your order becomes a custom build, and cancellation requests will receive store credit only.
Store credit can be used toward any Blazin’ Biddles Offroad product or future release.


🔹 Refunds After Production / Before Shipping

If your panels are completed but not yet shipped, cancellation is still possible but will incur a 25% fee to cover materials, finishing, and labor.


🔹 Refunds After Shipping

Once your order has shipped, all sales are final.
We will, however, support warranty claims or replacement of any defective components immediately upon inspection.


🔹 Production Delays

If production ever exceeds 30 days beyond the estimated ship date, you’ll be offered the choice to:

  1. Continue waiting with a small store credit bonus (we reward patience), or
  2. Receive a full refund, no fees.
