## What is DD Toolbox?

The DD Toolbox includes useful tools for setting up and analyzing high performance car audio systems. We understand installers have a lot going on while setting up a system, so the DD Toolbox layout was designed with this in mind. Easily switch between tools allowing fast and convenient use of the multiple tools. This allows you to do things like use the tone generator while punching numbers into the wattage calculator.

DD Toolbox features:

-Power Calculator for determining your systems actual output wattage and impedance

-Tone Generator

-DD Box Calculator

Connectivity Note: DD Toolbox requires connectivity in order to download dynamic configuration data (allows us to add new speakers/specs to the calculator for example, without having to create a new build). If you attempt to run it without connectivity you may receive an error.


Language Note: This version is capable of handling the native language of your device, but we have to provide a language file for it to use. If you're willing to help with translation to your language, please let us know, we'd love to make more languages generally available.

## Key features

- Power Calculator
- Tone Generator
- DD Box Calculator
- Dynamic configuration data download
- Multi-language support

### 1/5 — Box calculator does not work

*2023-08-18, version 2.0.2*

Every time I start the app on IOS it looks off and the box calculator does not work app has massive bugs till it’s fixed no point using it

### 1/5 — Box design program

*2022-04-12, version 1.1.4*

Box design program is only good for a square box. Don’t need a program for that. Truck boxes are not square, most custom systems the boxes are not square unless you just throw a box in your trunk and there is nothing custom about that.

### 5/5 — Excellent

*2022-02-26, version 1.1.4*

Excellent app

### 5/5 — Thank you DD

*2020-12-14, version 1.1.4*

*2020-02-07, version 1.1.4*

App will time out. Calculator does what it wants to. App is garbage

### 4/5 — Good app

*2017-12-03, version 1.1.4*

This is a nice app for figuring out the voltage to set your amp. The box size is nice just pick you music style 1st or the screen locks up. That’s why I give it 4 stars and not 5

### 1/5 — Please update

*2017-11-26, version 1.1.4*

I try to enter my info in the box building part but the keypad comes up and I can’t hit calculate because the keypad is in the way and there’s nothing I can do

### 2/5 — Faulty

*2016-08-04, version 1.1.3*
