Inside upgrade impedance simulator

Focal's Inside system upgrades include new aftermarket vehicle-specific speakers and subs, along with their Impulse 4.320 4-channel amp. Focal also offers a variety of cables and connectors that you'll need, including:

  • speaker wire harnesses for tweeters, subs, and center channel;
  • T-harnesses that connect the vehicle and factory radio to the upgrade system;
  • and extension cables to connect the T-harness to the amplifier.

In some installations, the factory radio shuts down if you remove the factory speakers. Focal's Inside SPK Sim impedance simulator connects to the input of a Focal Impulse 4.320 and makes sure the factory radio doesn't sense a lack of speakers then shut down displaying "Error."

Length: 9". Warranty: 1 year.

Product Research

Features

Overview: The IW-SPK-SIM speaker impedance simulator is necessary when adding the Focal Impulse 4.320 amplifier to some factory sound systems. Many modern factory radios feature built-in protection circuits that will mute the audio outputs if the factory speakers are removed. The IW-SPK-SIM is designed to simulate a speaker load to stabilize the signal from the factory system and provide the best possible audio.

Connection: The inputs and outputs are terminated with ISO connectors, and plug in-between the radio output side of the vehicle-specific harness (sold separately) and the ISO extension cable (also sold separately).
