About DD Toolbox

1. 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).

2. The DD Toolbox includes useful tools for setting up and analyzing high performance car audio systems.

3. We understand installers have a lot going on while setting up a system, so the DD Toolbox layout was designed with this in mind.

4. A DD Toolbox feature is the ability to easily switch between tools, allowing fast and convenient use of the multiple tools.

5. 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.

6. This allows you to do things like use the tone generator while punching numbers into the power calculator!

7. If you attempt to run it without connectivity you may receive an error.

8. If you're willing to help with translation to your language, please let us know, we'd love to make more languages generally available.

DD Toolbox Customer Insights

1. It's still a viable and helpful feature within a well-made, concise app with an efficient UI and helpful toolset, all for FREE! But the whiny cry-babies still hit the 1 star rate because they're spoiled and need to throw a tantrum and possibly a diaper change.πŸ€œπŸ˜«πŸ”¨πŸ–•πŸΎπŸ’©App has worked for years no issues.

2. Primarily P = VΒ² / R Which is super handy when tuning an amplifierPeople gripe about the box calculator being nothing new and that's great that YOU know all that but many people don't so to them it's invaluable and it doesn't constitute a low rating just because it didn't teach you anything.

3. But the way it worked before I could recommend it to someone who didn't understand the math and they could find the answers.

4. Can't wait for the version 2.0 to be finished so I can use this application again!The app is not working at all tried it on different phones stil the same problem.

5. The old power calculator worked better and was more flexible for entry and calculations.

6. Tried to open it a few days ago and it crashed and hasn't worked since.

7. A great free tool from Digital Designs.

8. The new update fixed the crashing but some of the features work differently.

9. This makes me sad because I religiously use it.Simple to use and easy to understand.

10. Granted with a little math you can figure all these out.

11. Until it started crashing.
