4 stars for a great tool/app, but...

I love this app for its ability to calculate everything I need for kicker enclosures. The only problem I am having is that the app shuts down whenever I try to save an enclosure. Am I doing it wrong?

Very handy

I have used this app in the "frequency generator" mode to efficiently two my full channel amp and sub amp. Equipment to do this is very expensive so I am glad to get the use out of a 4 dollar app. Useful if you're tuning amps, building a box, or are simply into everything kicker.

im not mad… just disappointed ,


Kicker doesn't supply BL or MMS in its literature so I thought their own software would. Not only do they not have but when you select a kicker product you are expected to supply the theile small specifications and it asks for… BL and MMS!!

I give it one star because zero stars isn’t an option.
