Which cable do I need?

If your head unit has RCA pre-outs, choose an RCA lead with one channel pair per amplifier channel pair, long enough to reach the amp without strain. If you are keeping the factory stereo, a vehicle-specific plug and play harness is usually the cleanest route, as it connects a compatible amplifier or DSP without cutting the loom. Check that the harness matches both your vehicle and your amplifier model. For power cables, see power and distribution.

RCA Cables & Wiring FAQs

Q: Why use shielded RCA cables?

A: Shielding helps reject interference from the vehicle's electrical system, which reduces the risk of whine and noise.

Q: What is a T-Harness?

A: A T-Harness sits between the factory wiring and the vehicle's audio system, so an amplifier or DSP can be connected without cutting wires.

Q: Can CEN fit my amplifier and harness?

A: Yes. Our Beeston, Nottingham workshop can supply and fit amplifiers, DSPs and harnesses, and tune the system once installed.
