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."
Product Features:
- Compatible with the compact 4-channel digital amplifier, IMPULSE 4.320
- ISO connectors to simplify mounting
