## Ultimate Car Audio App Reviews in United States

### **--- "Great but could be better with a few tweaks."
Love the app but I don't like how the cut sheet doesn't give port wall info on slot port and the 3d box is kinda pointless imo, electrical calculations are all over the place and inaccurate, hasn't been updated on apple in years but android gets frequent updates, but other than that it's good ig for simple box calculations and few other things but not much
-- CountryBeast1994, 2025-06-05

### ***-- "Update it plz"
Can you please get it update it been 3 year ago for apple update my buddy told me about this app and love it on android because it up to date but apple not
-- J-Sutton, 2025-01-08

### ***** "The best I’ve played yet!"
So far only complaint is how hard and dense the game gets so fast. Legendary characters don’t come fast at all. However the game is the best I’ve played so far
-- SlomJim0420, 2022-12-04

### *---- "No sound"
The app just stopped working, every time I try to do a sweet or a tone burst nothing plays.. this needs fixed!!
-- garrison00, 2022-11-19

### *---- "No preview"
Paid $2 just to see if this person made the box correctly and I put all the same info he did and got different tuning from the calculator and no preview to see how the box should look smh, wasted $2
-- Naliepooh, 2022-10-01

### *---- "No cut out sheet"
This app is old why is the cutout sheet coming soon you advertise it in the description.
-- Irapepigens, 2022-09-15

### ***** "Great app"
Love this app, have been using it since it was released.
-- c0mp0und, 2022-09-05

### ***** "Great App"
Has been amazing helping me design boxes and understanding displacement and port area
-- BobTheTowTruckDriver420, 2022-08-19

### ***** "amazing app"
the only thing i would recommend in the faq’s is information on 4th and 6th order walls. or a wall tab in general.
-- Cole420101, 2022-01-03

### ***** "This app is good but needs one thing"
I love this app very useful. One thing I would like for you guys to add is how to wire midrange and midbass speakers to a 4 channel amp the same way you guys show the “how to wire subs” tutorial.
