Hyundai Car Audio Upgrades UK

How to upgrade Hyundai car audio in 2026

Hyundai i30, ix35, Tucson, Santa Fe and i40 all share similar factory audio: a basic head unit, paper door speakers and limited Bluetooth on pre-2018 trims. A modern double DIN stereo, a pair of upgraded 6.5 inch component speakers and the right fascia kit raise sound quality, add wireless CarPlay and keep every factory control working as standard.

Single DIN or double DIN: which fits your Hyundai?

Almost every modern Hyundai uses a double DIN slot. The Connects2 CTKHY18 kit covers ix35 2014 on and the CT23HY16 panel handles the i800. We also stock vehicle-specific Grundig 6.8 inch and Sony DAB+ kits for i40 and Tucson with the correct steering wheel control adapter already paired.

Speaker upgrades for Hyundai doors

Hyundai front doors take a 6.5 inch driver. We supply the Connects2 CT25HY01 adapter bracket for ix35 and Tucson plus the CT25HY05 for Santa Fe 2014 on, so JVC, Pioneer or Alpine 6.5 inch coaxials drop in without modifying the inner door skin. The factory paper drivers tend to crack within five years on UK roads, so a coaxial or component upgrade is one of the most cost-effective improvements available.

• ix35 and Tucson. CT25HY01 brackets with 6.5 inch coaxials in matched pairs.
• Santa Fe 2014 on. CT25HY05 brackets for front and rear doors.
• i30 2011-2017. Universal 6.5 inch drivers with depth adapters where needed.

Steering controls, QI charging and DAB

The Connects2 CTSHY019.2 interface keeps stalk volume, track skip and phone answer working with a new head unit. For drivers who want wireless phone charging without sticking pads on the dash, the CTQIHY01 vehicle-specific QI charger sits cleanly in the centre console.

• Aerial adapter. Converts the Hyundai antenna fitting to DIN.
• CAN Bus interface. Keeps parking sensors, comfort settings and dash messages active.

Bass without losing the boot

For Tucson and Santa Fe owners who tow or carry a buggy, an underseat amplified subwoofer is the tidiest way to add real low end without sacrificing boot space. We pair these with high-level wiring so the install does not need a head unit with low-level pre-outs. For i30 and i40 owners on a tight budget, a shallow 10 inch active boot box gives proper musical bass without eating into the spare wheel well or the load space behind a folded rear seat.

Sound deadening for Hyundai doors

i30 and i40 doors benefit hugely from butyl sound deadening on the inner skin. New 6.5 inch speakers immediately sound tighter and lower noise on motorway runs makes hands-free calls clearer. Silent Coat and Dynamat sheets are our most popular for a typical four-door install.
