DD Toolbox vs Ultimate Car Audio App

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.
