The DD Toolbox includes several 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. A DD Toolbox feature not found in similar apps is the ability to easily swipe 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, all the while illuminating your trunk with the flashlight!

DD Toolbox features:

-Wattage/ Ohm's Law Calculator for determining your systems actual output wattage and impedance

-Tone generator that ranges from 20Hz to 20kHz

-DD Box calculator which uses DD's exclusive enclosure design theory to make a recommendation for maximum bass in your given enclosure space

-Flashlight function that's able to be toggled on/off from any screen.

What's New

Version 1.1.4

- Fix bug with international number formats

Ratings and Reviews

Good app


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

Please update

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

DD is severely underrated

I am a massive fan of DD Audio. They make incredible, competition-grade products. Why they're not more popular than Kicker, I'll never know. I like to compare Kicker to Mustang, and DD to Lamborghini. While they're both pretty cool sports cars, I would never take a Mustang to a competition with any of the real big dogs.
