Step 1: Choose Your Tool Box

First, decide which tool box you plan to use. This guide assumes a US General or Kobalt tool box; however, many other brands and styles are now available and can also be used successfully.

Step 2: Select Your Speakers

Speaker selection is divided into two build types:

Single Speaker Builds
Dual Speaker Builds

Once you decide how many speakers you want to run, you’ll need to determine the correct size.

For most mini tool boxes, the maximum single-speaker size is typically 5x7.

Compatible Single Speaker Sizes

3.5 inch
4 inch
5 inch
4x6
5x7

Compatible Dual Speaker Sizes

3.5 inch
4 inch
5.25 inch (note: not all 5.25 speakers will fit)

Recommended Budget-Friendly Speakers

Below are popular, budget-conscious speaker options. There are thousands of brands available—these are simply common and proven choices.

Step 3: Choose an Amplifier

Now that your speakers are selected, it’s time to choose an amplifier.

Single Speaker Builds

Use the 1001U

This amplifier also supports TWS (True Wireless Stereo), allowing you to pair two separate boxes together.

Dual Speaker Builds

Use the 1002T

While there are many amplifiers available on the market, these models are proven, budget-friendly options that have been used successfully in thousands of builds.

Step 4: Power Options

There are three main ways to power your amplifier:

Wall Power
Battery Pack
Power Tool Battery

Best practice is to run these amplifiers at the highest supported voltage to achieve maximum output with minimal distortion.

24V is ideal
Most power tool batteries are around 20V, which is acceptable
12V batteries will work with the booster on the 1001U but may increase amplifier strain
The 1002T will experience significant clipping at lower voltages, which can damage speakers

Power Tool Batteries

Most power tool batteries require a Low Voltage Cutoff (LVC) to prevent cell damage.

Rigid and Ryobi batteries typically do not require an LVC
DeWalt and Milwaukee batteries do require an LVC

Step 5: Cutting the Box

Templates can be found on the website:

Depending on your tools and preferences, speaker holes can be cut using:

Water jet
Plasma cutter
Dremel
Die grinder
Cut-off wheel
Jig saw (for some boxes)
Hole saw
Knockout die

Most builders prefer a hole saw when possible. Avoid bi-metal blades, as they wear quickly. A carbide-tipped hole saw is strongly recommended.

Hole saw size will vary depending on the speaker used.

DC Input Jack

Used for charging standalone batteries or powering the unit from a power supply.
DO NOT use with power tool batteries, as they require a smart charger to interact with their BMS system.

Always verify proper wiring and voltage compatibility before use.

LED Lighting

5V LEDs can be powered via a standalone 5V converter:
