BBOR V.2 Lower Door Speaker Panels for 1973–1991 Squarebody Chevy & GMC Trucks, Blazers, Jimmys & Suburbans

Which panel fits my truck?

• '73–'76 Chevy/GMC truck, Blazer, Jimmy or Suburban: V2 (this page) is the panel that fits your doors.
• '77–'91: V2 or V3. V2 bolts in with six screws or rivnuts and runs 6.5" coaxials. V3 is a slimmer 3.5" panel with magnetic or bolt-on mounting, plus rear-door and 4-door sets — pre-order, up to 90 days to ship.
• Rear doors (Suburban or crew cab): that's V3. V2 is front doors only.

Not sure? Text me a photo of your door: 530-327-8811. I'll tell you which one fits before you order.

I built these because I wanted them on my own truck and nobody made them. Lighted, color-matched, fit to your Squarebody — the panel I wished existed, now built for yours.

Not a catalog part. Not a universal pod hacked onto your door. A custom-fabricated panel built to your truck, your interior, your taste — so every time you open that door, there's no doubt in your mind it's perfect. These aren't for everybody. But if you care about how your truck looks, feels, and sounds, they're built for you.

Choose Your Build

★ BASE — $595

Raw aluminum and black finish, no lighting. The clean, durable foundation — built right, no extras. Pick any of our standard grille designs at no extra charge, run your own 6.5" speakers, and add upgrades if you want them. The honest starting point that still looks like nothing else on the road.

★ PREMIUM — $795 · MOST POPULAR

Everything Base gives you, PLUS the three things that set it apart: color-matched to your interior, 3-light ambient lighting that comes on with your door, and sound deadener on the panel with all wiring included. Looks custom, sounds clean, lights up when you open the door. Same finish, speaker, and grille choices as Base.

★ FULLY LOADED — $1,149

The works, done my way. Everything in Premium PLUS a polished or powder-coated finish, a custom grille design of your choice, and DC Audio Pro coaxial speakers already installed. Fully assembled and ready to bolt in — exactly the way I'd build it for my own truck. Nothing to pick. It's all in there.

Pick Your Grille Design

Every set comes with a grille in the design of your choice — these standard designs are no extra charge. Pick yours from the list below (you'll confirm it with me before I build):

Want a design that's not on this list? That's a custom grille (+$140 — already included on Fully Loaded). Just tell me what you're after when I reach out.

How You Pick Your Color

Premium and Fully Loaded panels are color-matched to your interior. You don't pick the color here — and here's why: every set is custom-built, and I confirm your exact color and grille with you personally before I build, so it comes out perfect. Here's how it works:

1. Place your order and pick your package, finish, and speakers above.
2. Right after, I'll reach out by text or email to lock in your color and grille — I can match any factory interior color from 1973–1987, or whatever color you've got in mind.
3. You sign off on a final approval, and then I build it.

No guesswork, no surprises — nothing gets made until you approve it. (Base panels come in black with raw aluminum — no color match.)

Upgrade Options (Base & Premium)

• Polished finish: +$125
• Powder coat, white or black (aluminum backing & grille): +$100
• Skyhigh coaxial speakers: +$135 / set
• DC Audio Pro coaxial speakers: +$240 / set
• Custom grille design (anything not on the standard list): +$140
• Standard grille designs, plus color match on Premium: no extra charge

(Fully Loaded already includes the polished/powder finish, custom grille, and DC Audio Pro speakers.)

What Comes With Your Panels

• Direct install support from a master tech. Get my direct line during your install — text or video. You reach the guy who designed these, not a help desk. 20+ years a master tech. I'll get you through it.
• The Squarebody Wiring Cheat Sheet. Where to find switched and door-trigger power, how to test it, and how to wire the lighting clean the first time. The hard part, already figured out.
• Founding Customer Feature. Send me photos or video of your finished install and earn store credit toward your next order. Your truck joins the Blazin' Biddles lineup, and you get rewarded for it.

Fitment

Fits all Squarebody Chevy/GMC trucks, Blazers, and Suburbans, 1973–1991 — front doors only. Fits regular, extended, and crew cab. Looks best on '78 and up, where it matches the door body lines. These replace the factory carpeted panel below your door panel (an add-on, not a full door-panel replacement). Works with factory or rewrapped doors; a full custom interior may not be compatible.

Install

Not a no-tools drop-in, but no big cutting either — six self-tapping screws (or drill + rivnuts) and one wire pass-through hole. No giant speaker holes hacked into your doors. Most installs run 3–5 hours with a drill, a few bits, and a Phillips. You should be handy with basic wiring and have a wiring diagram for your truck — I'll tell you which wire to tap, but not its color on your specific vehicle.

Speakers & Electrical

Built for 6.5" coaxial speakers (no tweeter cutouts). Run your own 6.5s or add ours. Works with any head unit or amp. Lighting is 3 white ambient lights, wired to your door switch, headlight switch, or a panel switch.

Built To Last

All stainless hardware — no rust. Solid PETG-GF construction, no thin sheet metal to warp or rust. Premium and Fully Loaded include sound deadener and acoustic foam in the chamber, so no rattles. Run in my own rigs for over a year through real heat and cold — zero issues, and zero complaints from every set out in the field.

Is It Worth The Price?

It's not a speaker box. It's a custom-fabricated, lighted, color-matched panel that doesn't exist anywhere else, finished the way you want it. We're not the cheapest. We're the ones who get it right.

The Blazin' Biddles Guarantee

• You approve it before I build it. You sign off on your colors, finish, and grille before anything gets made. No surprises when the box shows up.
• If it's wrong, it's on me — I fix it, 100%, at no cost to you. That's the whole name on the product.
• 3-year defect warranty on materials and workmanship. (Normal wear, drops, or misuse aren't covered — a real defect is on me.)
• Changed your mind? Because every set is custom-built to your choices, custom orders can be returned for a refund minus a 35% restocking fee plus shipping. The approval step means this almost never happens — but it's there if you need it.

Why I Can Only Take So Many

I'm not a warehouse. Materials come in for a limited number of sets each month, and I build and assemble every one by hand myself. When the month's slots are filled, you're on next month's batch. That's not a sales tactic — it's just how these are made: small-batch, by hand, one truck at a time. If you want yours in this month's run, get your order in before the slots are gone.

Build yours the way you've always pictured it.
