Stinger SI4212 4000 Series 2-Channel RCA Interconnect, 3.6m

Audiophile-grade 2-channel OFC RCA interconnect from the Stinger 4000 Series C3 Tech, split-tip connectors, directional twisted-pair construction. 3.6 metres for compact vehicle installations.

Product Overview

The Stinger SI4212 is the 3.6-metre (approximately 12ft) 2-channel version of the 4000 Series RCA interconnect range. It shares the same construction quality as the SI429 (5m) and SI4220 (6m) OFC conductors, C3 Tech, directional twisted-pair shielding, and split-tip connectors in a shorter 3.6-metre length suited to compact cars, hatchbacks, and installations where the amplifier is mounted close to the head unit.

Features & Benefits

  • 2-channel OFC RCA — suited to stereo or mono amplifier connections
  • C3 Tech (Continuous Connection Construction) for unmatched signal transfer
  • Split-tip connectors for superior contact and signal transfer
  • Directional twisted-pair construction — interference rejection
  • Compact connector ends with colour-coded channel identification
  • 3.6-metre length — suited to compact vehicles and short cable runs

Frequently Asked Questions

When would I choose the SI4212 over the longer 4000 Series RCA cables?

The SI4212 at 3.6m suits compact cars and hatchbacks where the amplifier is in the boot close to the rear seats — a typical run of 3–4 metres. Choosing a cable matched to the actual run length avoids excess cable bundling and the associated noise risk. For standard sedans (5m) or larger vehicles (6m), see the SI429 or SI4220.

What is C3 Tech?

C3 Tech (Continuous Connection Construction) is Stinger's proprietary method ensuring the conductor maintains continuous contact with the connector — reducing resistance and improving signal consistency throughout the cable.

Is the SI4212 directional?

Yes. The SI4212 uses directional twisted-pair construction and should be installed with signal flowing from the head unit to the amplifier for optimal noise rejection.

Can I use the SI4212 for a subwoofer (mono) connection?

Yes. One channel of the 2-channel cable can be used for a mono subwoofer connection where the amplifier supports a dedicated mono input.

What if 3.6m is too short for my vehicle?

For longer cable runs, see the Stinger SI429 (5m), SI4217 (5m), or SI4220 (6m) — all from the same 4000 Series range with identical construction quality.
