Which CEN Enclosures, Wiring & Accessories should I choose?
For subwoofer enclosures, choice depends on your vehicle and preferred mounting position. The T5 8-inch under-seat box is the compact carpet-trimmed option for older Transporters, while the T5/T6/T6.1 10-inch under-seat box offers 10 litres and is supplied unfinished ready to wrap or carpet. The wheel arch 10-inch enclosure provides the most volume at 15 litres in a finished carpet box. The VW Caddy box is purpose-built for behind the passenger seat in the Caddy. For speaker adapters, the SAVW31 adds vehicle-specific plugs for front door fitment in listed models; the SAVW30 is the bracket-only version.
For wiring, the ISO extension lead adds 15cm without cutting, while the bare wire adaptor suits installs requiring bare ends. The CNK8A covers everything needed for an amplifier install up to 800W RMS. Use the fuse tap kit to hardwire a dash cam or 12V accessory from the fuse box, and the start stop voltage stabiliser to prevent head unit resets on stop-start vehicles. Choose the Fakra-to-RCA adaptor, DAB splitter or T6 USB retention cable according to your specific vehicle and install requirements.
CEN Enclosures, Wiring & Accessories FAQs
Q: What is the difference between the SAVW30 and SAVW31 speaker adapter brackets?
A: Both are 6.5-inch adapter brackets for selected VW and Skoda models; the SAVW31 includes plugs and is designed specifically for front door fitment in models including the Passat, Tiguan, Touran, T-Roc, Octavia and Superb, while the SAVW30 is the bracket-only version without plugs.
Q: Which VW Transporter subwoofer enclosure offers the most internal volume?
A: The wheel arch 10-inch enclosure for the T5, T6 and T6.1 provides 15 litres of internal volume, compared with 10 litres for the 10-inch under-seat box and 8 litres for the 8-inch under-seat T5 enclosure.
Q: What is included in the CNK8A amplifier wiring kit?
A: The CNK8A includes power, ground, RCA, remote and speaker cables, plus an AGU fuse holder with a 60A fuse — everything needed to connect an amplifier in a system running between 400W and 800W RMS.
Q: What does the Start Stop Voltage Stabiliser do?
A: It fits inline on an ISO power cable and prevents an aftermarket head unit from resetting during engine crank on stop-start vehicles — specifically those where both the ignition and permanent feeds drop during restart.
Q: Can CEN fit these products at their workshop?
A: Yes — CEN has a fitting workshop in Beeston, Nottingham, where products such as subwoofer enclosures, speaker adapters, amplifier wiring kits and dash cam hardwire kits can be professionally installed to your vehicle.
