About the Connection BT4 250

From our tech experts at CEN

The Connection Best BT4 250 is a competition-grade 4-channel RCA interconnect cable from Connection by Audison, 2.5m (8.2ft) long. It connects a head unit or processor to a car amplifier, with CDAS™ double aluminium shielding and WTP™ twisted pair conductors delivering over 100dB noise rejection. Platinum satin machined metal contacts and a tug-proof sealed internal connection add reliability.

Who it suits

This cable suits anyone fitting a 4-channel amplifier who wants interference-free signal. For longer cable runs, the Connection Best BT4 550 offers 5.5m of reach. If you need 6 channels at 2.5m, consider the Connection Best BT6 250.

Our tech experts advise

Measure your cable run from head unit to amplifier before ordering; 2.5m suits most compact and medium-sized cars. The built-in remote turn-on wire saves running a separate conductor during installation. Car audio fitting is priced per vehicle — contact us about installation in Nottingham.
