About the RetroSound M4-308-409-39-78
From our tech experts at CEN
The RetroSound Becker Style Motor 4 (M4-308-409-39-78) is a period-style classic car stereo finished in black pebbled inserts, black and chrome buttons, and a chrome faceplate. It features a DAB/DAB+ tuner, AM/FM RDS with 30 presets, Bluetooth 5.0 with hands-free microphone, and a 25W RMS x 4-channel amplifier. Dual RCA pre-outs, a dedicated subwoofer output, and two rear USB ports are also included.
Who it suits
This is a good fit for classic car owners who want DAB reception and Bluetooth alongside a factory-correct appearance. The Becker-inspired styling suits vehicles that originally carried a Becker-type radio. If DAB is not a priority, the RetroSound Motor 2 offers Bluetooth and FM/AM without the DAB tuner.
Our tech experts advise
RetroSound uses a modular design, so bezels, knobs, faceplates, and mounting hardware are sold separately — confirm fitment before ordering. The unit is compatible with 12V negative earth vehicles only (11.5–14.4V). Professional fitting is priced per vehicle; see our car audio installation in Nottingham page for details.
