About the Connection ST2 550
From our tech experts at CEN
The Connection Sonus ST2 550 is a 5.5m (18ft) 2-channel RCA interconnect cable from the Connection by Audison Sonus ST series. It connects a head unit to an amplifier using WTP balanced conductors and 110% twisted Mylar with double aluminium shielding for over 115 dB noise rejection. The SOFT TOUCH outer jacket makes it flexible and easy to route.
Who it suits
The 5.5m length is well suited to estate cars, MPVs, and vans where the amplifier is mounted in the rear. For slightly shorter runs, the ST2 450 at 4.5m may suit better. For a step up in cable quality, see the Connection Best BT2 550.
Our tech experts advise
Measure your cable run before ordering, allowing extra length for routing around trim and door sills. The die-cast Y block protects conductors at the split point, and tug-proof sealed connectors ensure a reliable fit. For 4-channel amplifiers, a 4-channel RCA lead is required rather than this 2-channel cable; explore the full Connection range for more options.
