Caliber Portable Car Audio Accessories UK

Buying portable car audio accessories in 2026

The portable car audio category is where you go when you want a quick, plug-and-play upgrade without rewiring the dash or swapping the head unit. Bluetooth FM transmitters, compact portable car stereos, wireless charging alarm clocks and marine LED controllers all live here. Bass Junkies stocks the genuine UK editions so you get the right firmware, the right plug, and the right warranty cover from day one.

FM Bluetooth transmitters explained

A Bluetooth FM transmitter plugs into your 12V socket and broadcasts audio from your phone to your car radio on a clear FM frequency. Modern Caliber units add hands-free calling, fast USB-A or USB-C charging and microSD playback, so a car with a basic radio can stream Spotify, take calls and charge two phones at the same time. Look for PD or QC fast-charge support if you run a modern smartphone.

Portable DAB+ car stereos

Caliber portable car stereos pair a built-in DAB+ tuner with Bluetooth, USB and SD playback. They sit on the dash or in a cup holder, run from 12V power and feed your existing speakers through an FM link or RCA out. They are ideal for older vans, kit cars, classic motors and second vehicles where a full single-DIN install is overkill.

Qi wireless charging clocks and desktop chargers

Caliber Qi wireless charging alarm clocks live happily in the cab, the workshop or the bedside table. You drop your phone on the pad, set the alarm, and the night light handles the rest. Useful for drivers, fleet operators and anyone tired of fishing around for a cable in the dark.

Marine and powersport LED control

The Kicker KMLC marine RGB LED controller is the bridge between your boat, jet ski or off-road build and any KMLC-compatible Kicker RGB lighting. Waterproof, simple remote operation and full colour control, all from one tidy module.
