CEN is more than an online shop. From our premises at Unit 25 Technology Drive, Beeston, Nottingham, our installers supply, fit, repair and tune the equipment we sell — car audio, dash cams, security and more — backed by decades of combined experience and authorised-reseller warranties on every brand. We are appointment only, so get in touch before travelling.
Audio upgrades
Speaker upgrades, DSP amplifiers, subwoofers, sound deadening and Apple CarPlay head units for cars, vans and campers — from plug and play improvements to complete tuned systems from Focal, Hertz, Audison, Helix and JL Audio.
EV audio upgrades
Electric vehicles are the best listening rooms on the road. Plug and play speaker kits, DSP amps and subwoofers for Tesla Model 3 and Model Y and the wider EV market, fitted with zero permanent modification.
Dash cam installation
Front, rear and 3-channel dash cams from BlackVue, Thinkware, VIOFO and Nextbase, hardwired with hidden cabling, fused power and parking mode configured properly — including battery packs for EVs and fleets.
Radio repairs
Head units, amplifiers and speakers repaired by people who understand them, with over a decade of repair experience and warranty-backed work — including classic car radios.
Vehicle security
Protection against keyless and relay theft: the Autowatch Ghost II immobiliser, trackers and alarm upgrades, discreetly installed.
Demo vehicles
Hear real systems in real vehicles before you spend a penny. Book a listening session, bring your own music and compare upgrade stages back to back.
