What's in the Library

Product Categories

  • Amplifiers (Class A/B/D, mono, multi-channel)
  • Speakers (component sets, coaxials, subs)
  • Signal processors (DSPs, equalizers)
  • Head units (source units, OEM integration)
  • Wiring (wire, fuses, connectors, terminals)
  • Enclosures (sealed, ported, bandpass)
  • Accessories (sound deadening, mounting hardware)

What's Stored Per Product

  • Brand and model name
  • SKU / part number
  • MSRP
  • Key specs (power ratings, impedance, sensitivity, T/S parameters for speakers)
  • Product image (where available)
  • Compatibility notes

Searching the Catalog

1
Go to Hardware from the sidebar.
2
Type in the search bar β€” enter a brand name, model number, or product type (e.g., "JL Audio 12W7" or "4-channel amplifier").
3
Filter by category (Amplifiers, Speakers, Subs, etc.) using the dropdown. Sort by price, brand, or relevance.
4
Click any product to see full specs, image, and MSRP. From the product detail page, you can add it directly to an open work order.

Wiring & Impedance Calculator

The wiring calculator helps you plan speaker wiring configurations β€” finding the final impedance when wiring multiple speakers in series, parallel, or combinations.

Why this matters: Amplifiers have a minimum impedance rating (typically 2Ξ© or 4Ξ©). Wiring multiple subwoofers together changes the total impedance the amp sees. Wire incorrectly and you risk amp shutdown or damage.

How to Use the Wiring Calculator

  1. Go to Hardware β†’ Wiring Calculator
  2. Select your subwoofer model (pulls speaker impedance from the library automatically)
  3. Enter the number of voice coils (DVC = dual voice coil)
  4. Select the wiring configuration: Series, Parallel, or Series-Parallel
  5. The calculator shows the final impedance the amplifier will see, and a wiring diagram
ConfigurationFormulaWhen to Use
Series Total Ξ© = sum of all speaker Ξ© Raises impedance β€” fewer subs or higher-impedance target
Parallel Total Ξ© = 1 / (1/Ω₁ + 1/Ξ©β‚‚ + ...) Lowers impedance β€” more power from amp
Series-Parallel Combination of both Multiple woofers, specific target impedance

Importing Your Inventory from Excel

If your shop already has a product inventory in a spreadsheet, you can import it directly into Tuning Labs. This populates your work orders with your own inventory instead of searching the general catalog.

1
Go to Hardware β†’ Import Inventory.
2
Download the import template (Excel .xlsx format). The template shows you the required columns: Brand, Model, SKU, Category, MSRP, Cost, Stock Qty.
3
Fill in your inventory and save the file.
4
Click Upload File and select your filled-in Excel file. The import runs automatically.
5
Your products appear in the My Inventory tab. They can be added to work orders just like catalog products.
πŸ’‘ Inventory is shop-specific. Imported inventory is visible only to users on your Shop account β€” not shared with other shops or public.

AI Compatibility Check

The AI Advisor's Compatibility Check mode uses the hardware library to verify that your amp, speakers, and DSP will work well together. It checks:

To run it: go to AI Advisor β†’ Compatibility Check and select your components from the hardware library.
