Please Read Before Purchasing
This vehicle-specific package is primarily intended for professional installation. Some vehicle-specific systems may suit confident DIY installers, but HELIX packages typically require more advanced installation and tuning knowledge.

This particular package requires additional wire plugs and speaker adapters to become fully Plug & Play. The included parts should therefore be checked carefully before installation.

Speaker connectors may not be included and should be confirmed before purchase.

Minor modifications may also be required depending on the vehicle's exact year and trim.

Installation and tuning fees are not included in the online product price.

Who This Package Is For
This package is designed for Toyota GT86 and GR86 owners seeking a complete speaker, subwoofer and DSP-amplified audio upgrade rather than a speaker-only or subwoofer-only solution.

It is particularly suited to customers wanting HELIX COMPOSE speakers throughout the cabin, dedicated 10" bass reinforcement and DSP amplification that can be professionally calibrated for the vehicle.

The package is primarily intended for experienced installers and trained professionals, with professional DSP tuning recommended for the best system setup.

Installation & Tuning Notes
The specified upgrade method is: No factory amplifier → new amplifier integration

The package integrates a new DSP amplifier into the vehicle and includes the required wiring harness. Professional DSP tuning is recommended to optimise the upgraded speakers and subwoofer for the vehicle's acoustic environment.

Minor modifications may be required depending on the exact vehicle year and trim.

This package is not fully Plug & Play as supplied, as additional wire plugs and speaker adapters may be required. Speaker connectors may also need to be sourced separately.

Installation and tuning charges are separate from the online product price.
