In this guide
RetroSound's new Motor 4 stereos have arrived at CEN, and they solve the classic car owner's dilemma: modern sound and DAB radio without a modern-looking hole in a period dashboard. The Traffic and Monza models are in stock now at £399 each.
Period looks, current spec
The Traffic Motor 4 and Monza Motor 4 are built for classic dashboards — adjustable mounting designed around original apertures, with faces that look right against chrome and walnut. Behind the vintage styling sits a thoroughly current stereo: DAB digital radio, Bluetooth streaming and hands-free calling.
Which one?
It's a styling choice — Traffic and Monza offer different faceplate looks for different eras and interiors, with the same £399 price and the same Motor 4 platform underneath. If you're unsure which suits your dash, send us a photo of the original unit and we'll advise.
The bigger picture for classics
A stereo like this pairs beautifully with discreet speaker upgrades and even hidden amplification — a system that sounds like 2026 while the cabin stays firmly in period. It's one of our favourite kinds of installation, and the Motor 4 range makes the head unit part of it easier than it's ever been.
Frequently asked questions
Will a Motor 4 fit my classic car?
The Motor 4 platform is designed around classic dashboard apertures with adjustable shafts and period styling. Tell us your car and we'll confirm fitment before you order.
Can I still run my original-style speakers?
You can, though pairing the new stereo with discreet modern speakers transforms the result — we can recommend options that stay hidden in original locations.
Does CEN install classic car stereos?
Yes — sympathetic installation from our Nottingham premises, keeping original dashboards intact.
