Love this app...this is the only app I will EVER use for car audio box building 🔥🤌
★★★★★Leon Ray· Feb 19, 2021
Great update! This is the most accurate enclosure calculator you will find! The changes to single vs multiple subs (and how cutouts affect volume with multiple subs - thanks Thomas), correct port volume, this is so worth it. Plus the new Cone Area Calculator is cool, the Electrical Calculators have been useful, now there's Tone Generators/Sweeps. Just get this app!

Excellent resource for car audio enthusiasts... I've been using the free version for a while and just upgraded to the paid version! Well worth the price for such a valuable resource!

The wire size calculator said "Holy wire size Batman". That was its calculation for me. 12v, 900 watts, single 8ft run of CCA and the wire size I need is "Holy wire size Batman". 🤷♂️ So then I went to the debug mode to send a screenshot of my issue (like it said to do) and the screen was unresponsive. I clicked on email 5 or 6 times. Then I just waited. Nothing. I clicked email some more. Then waited some more. Still nothing. It needs work but feels abandoned.

Terrible, after trying again and again.... Doesn't give port design In the box preview. Seems to poorly represent the actual design of the box as well.the free version is just as good. Waste of $$$$$
