TuN Express

JL Audio, Inc

About this app

Use your Android smartphone to set up and command a streamlined, basic DSP feature set on a compatible JL Audio DSP-based amplifier, via Bluetooth LE connection. TüN™ Express automatically recognizes a compatible JL Audio product and offers a clear user interface optimized for that specific product. A simulation mode is included to simulate any product or perform offline setup.

TüN™ Express 3.1 is compatible with JL Audio VXi and MVi amplifiers. It is not compatible with FiX™ or TwK™ processors.

Important: requires a VXi-BTC Bluetooth® Communicator accessory connected to VXi or MVi amplifier

Ratings and reviews

Not a fan. Very limited functionality. Can only do basic setups, similar to what you would do temporarily after an install but before a full tune. JL Audio needs to make a real smartphone tuning app (or re-enable TuN Mobile on smartphones). It's competitors are already heading that direction. Also can't access tunes done on TuN Mobile or TuN 3.0 versions. Makes TuN Express useless for quick tweaks.

Every android device I use, it'll show up then when it tries to connect, I get 2 errors. 1. Update the vxi amp first via computer 2. Kinda like turn it on and off again Nothing I do works. This sucks.

I can't get Express to connect to either of my Android phones (Note 10+ nor Tmobile Revvl) using the BTC. Wife's iPhone 11 Max worked instantly, something with Android & Express isn't working....
