About the Connection BT6 550
From our tech experts at CEN
The Connection Best BT6 550 is a 6-channel, competition-grade RCA interconnect cable, 5.5m (18ft) long, from the Connection by Audison BT series. It connects a head unit or processor to a car amplifier, with over 100 dB noise rejection from CDAS™ cascaded double aluminium shielding and WTP™ twisted pair conductors. A built-in remote turn-on wire is included.
Who it suits
It suits anyone running a system that requires six independent RCA signal paths — such as a 3-way active setup — over a longer cable run. For a shorter installation, the Connection Best BT6 250 (2.5m) is an option.
Our tech experts advise
Measure your cable route from head unit to amplifier before ordering; 5.5m suits most hatchbacks, saloons and larger vehicles with a boot-mounted amp. Route the cable away from power leads to prevent interference. The flexible matt black jacket makes dressing the cable straightforward. Installation is priced per vehicle — ask us about fitting at our Nottingham workshop.
