Authorized Manufacturer's Representative
Dynamat.
Represented in Northern California & Northern Nevada.
Reliable Product Marketing is the factory-authorized Dynamat rep for the territory — car audio, marine, RV, restoration, and industrial. Training, dealer programs, and a rep with 30 years in the bay and behind the counter.
Constrained layer damping — the same physics automakers apply robotically on the assembly line. Dynamat brings it to the panels the factory skipped.
Two ways in.
I own a vehicle
Quieter, cooler cabin. A stereo that finally sounds right. Dynamat is installed by authorized shops across the territory — tell us your vehicle and your goal, and we'll point you to the right one.

Sound treatment is the highest-margin shelf in the store — and Dynamat is the name customers walk in asking for. Below: what to stock, what to sell, and the program that gets you there.
See What to StockTwo layers. That's the whole system.
Dynamat makes a lot of SKUs. You don't need most of them to do 90% of jobs. Every install is a base layer that kills panel vibration, plus a second layer that blocks heat and airborne noise. Stock the pillars, special-order the rest.
Base Layer
Kills Vibration
Dynamat XtremeStock It
The flagship. 100% butyl core, 4-mil aluminum skin. Doors, floors, trunks, roofs — the first layer on virtually every job. If you stock one thing, it's this.
Pro XOrder As Needed
Same butyl chemistry, twice as thick, 5-mil aluminum. For SPL builds, big commercial panels, and worst-case resonance.
SuperLiteOrder As Needed
30% thinner and lighter. Weight-sensitive builds, aircraft-style jobs, and light-duty panels.
Second Layer
Blocks Heat + Noise
DynalinerStock It
Closed-cell foam that layers over Xtreme. Blocks heat, absorbs airborne noise, won't hold water. 1/4″ is the default; 1/8″ and 1/2″ fill the gaps.
DynapadStock It
One-pound-per-square-foot composite barrier for floors and firewalls. The answer to road roar and exhaust drone that damping alone can't fix.
Hoodliner & DynaDeckOrder As Needed
Hoodliner soaks engine noise under the hood; DynaDeck replaces carpet padding in classics and off-road builds. Attachment sales on resto work.
What they say. What you sell.
Surgical treatment — the right product on the panel causing the problem, the way OEMs do it on the line. Not a truckload of mat on every surface.
My new speakers sound weak.
An untreated door is a leaky, rattling speaker box. Damping the door skin is the cheapest sound-quality upgrade in the store.
Sell: Pro Speaker Kit — every speaker install
The highway noise wears me out.
Road noise is structure-borne through the floor. Damp the pan, then barrier it — that's the one-two that customers feel on the drive home.
Sell: Xtreme floor + Dynapad
My bass makes the whole car buzz.
Trunk lids and rear decks resonate right in the sub's range. Treat them and the bass tightens up instantly — a demo that sells itself.
Sell: Xtreme trunk kit — every sub install
Rain sounds like a drum. The cab bakes.
The roof is the biggest untreated panel in the vehicle and the main solar load. Damp it, then insulate it.
Sell: Xtreme roof + Dynaliner 1/4″
Something plastic is rattling.
Trim buzz isn't a damping problem — it's contact. A strip of Dynaliner on the back of the panel decouples it for pennies.
Sell: Dynaliner 1/8″ on trim backs
Where does it all go?
Doors, floor, firewall, roof, trunk — every zone has a prescription. Ask us for the treatment map and custom-cut kit list for popular vehicles.

A note to shops
If you're not selling CLD with every speaker install, you're doing your customer a disservice on their audio upgrade. The best speakers in the store can't perform in an untreated door — damping the panel is part of the install, not an add-on. Make it line one on the quote. Dynamat even boxed it for you:
Dynamat Pro Speaker Kit
- Treats 2 speakers up to 10″ — one kit per pair of doors
- (2) 18″×18″ Xtreme sheets — stop inner-door vibration
- (2) 10″×10″×1″ Back Wave CCF — cut back-wave distortion
- (4) 32″ Pro Speaker Ring strips — seal the speaker frame
What not to sell
One layer of damper is enough — a second layer of CLD on a treated panel is wasted money. 100% coverage isn't the goal — strategic coverage does the job; that's how OEMs apply it. And wind noise above the door line isn't a damping problem — that's seals and absorption, not more mat. Selling it straight is why customers come back.

From the Central Valley to the Nevada high desert, parked interiors bake all summer. Asphalt-based deadening — the core of most bulk import mats — can soften, sag, and stink as temperatures cycle. What looked like a bargain ends up dripping behind a door panel.
Dynamat's 100% butyl core stays put and keeps damping across the full range a parked car actually sees. That's chemistry, not marketing — and in this climate it's the difference that shows up two summers later.
