Comments on Kicker U for Android

★★★★★ Dell White · May 20, 2018

This is an outstanding app, Stillwater designs (Kicker)has been making subs forever excellent products and service. Now I ready and prepared to build a box for my new 2 -Kicker Comp R DVC 10's 4 ohm. But the only thing I've noticed with the app is it shows my 2 subs rated combined 1200 watts input required when it should be 800 watts but, Im going to set my amp at 4 ohms 938 watts should be good.....anyway Thanks again for your awesome products.

Could let you do just a little more but so far so good all my boxes are having good results so far and the wiring options are definitely tight and understanding how to build is tight too

★★★★★ joshua hunt · Aug 25, 2021

A good layman's terms box builder. Yes it's quirky but if you pay attention between tabs you'll figure out what's going on. And the answer to the guy below... the port volume is included in the final rendering/cut-sheet, so you get to choose how & where you want it. If you can't figure out how to design that you probably shouldn't be building an enclosure to start.

★☆☆☆☆ Nathan Yeager · Nov 13, 2017

The free app is just as capable. The custom features are a joke. The paid and the free app build different boxes for my subs, and when I enter the free app sub specs into the paid app it shows garbage results/specs. So which one of the apps is wrong? Or are they both be info. I'm pissed, I don't know how to get a refund but this app is false advertising.

★★☆☆☆ MrHakisak · Nov 28, 2024

Doesn't have my kicker subwoofer (L7T). Ported box builder doesn't help you with port specifications at all, just tells you to make a box.

★☆☆☆☆ Jacob Eves · Aug 30, 2016

WTF? Downloaded this app in effort to help me design a custom box. The calculator is so up the pole it's not funny. I followed the instructions, only to have none of the dimensions that I entered show up in the final listing, and dimensions so small they're not humanly possible. And it would be really good if the dimensions that get calculated would actually come up with a scale drawing or a plan, so you know what dimensions go where. Improve it. This doesn't even deserve one star.

★☆☆☆☆ Adam Carey · Jun 24, 2020

Doesn't even have Kicker's flagship square L7 subs in the box builder, and doesn't include the port/vent when building the materials list or show one in the exploded view. The two things I specifically needed....
