Toyota GT86, GR86 - Speaker & Left-Side Subwoofer DSP Amplified Package | HELIX Ci3

Overview
Upgrade the sound system in your Toyota GT86 or GR86 with a complete HELIX COMPOSE Ci3 speaker, DSP amplifier and left-side subwoofer package. This vehicle-specific system combines front FlexMount component speakers, rear FlexMount coaxial speakers, dedicated DSP amplification and a loaded subwoofer enclosure for a more comprehensive audio upgrade.

A dedicated subwoofer driver and vehicle-specific left-side enclosure add amplified low-frequency reinforcement, with a supplied remote control for convenient subwoofer level adjustment.

Please Read Before Purchasing
This package is primarily intended for professional installation and experienced installers. Although the system is largely designed around Plug & Play integration, additional wire plugs and speaker adapters are required to make this particular package fully Plug & Play.

Speaker connectors may not be included. The exact vehicle year and trim should also be confirmed before purchase, as minor installation modifications may be required.

Installation fees are not included in the online product price.

Who This Package Is For
This package is designed for Toyota GT86 and GR86 owners looking for a more comprehensive sound system upgrade rather than replacing speakers alone.

It is particularly suited to customers wanting upgraded front and rear speakers, dedicated subwoofer reinforcement and DSP amplification in one system.

HELIX DSP systems require appropriate installation and advanced tuning knowledge, so professional installation and calibration are recommended.

Installation & Tuning Notes
The package uses a no factory amplifier → new amplifier integration upgrade method.

Most of the system is designed around vehicle-specific integration, although additional wire plugs, speaker adapters or minor modifications may be required depending on the vehicle's exact year and trim.

Professional DSP tuning is recommended to optimise the system for the vehicle's acoustic environment. Installation and tuning charges are not included in the product price.
