Subaru Forester - Speaker & Subwoofer DSP Amplified Upgrade Package | HELIX Ci5

The Subaru Forester Speaker & Subwoofer DSP Amplified Upgrade Package | HELIX Ci5 is a vehicle-specific sound system upgrade combining HELIX COMPOSE Ci5 front and rear speakers, a loaded subwoofer enclosure and DSP amplification.

The package upgrades the front stage with two FlexMount tweeters and two FlexMount component speakers, adds two rear FlexMount coaxial speakers, and includes four FlexMount speaker adapters. Dedicated low-frequency reinforcement is provided by the loaded subwoofer enclosure, while amplification and system processing are handled by the included DSP amplifier and radio-specific amplifier T-harness.

Official bundle media clearly identifies the amplifier as the MATCH UP 6DSP, a six-channel amplifier with an integrated seven-channel DSP. This gives the package amplified front, rear and subwoofer capability together with professional DSP processing and calibration.

Please Read Before Purchasing
These Plug & Play upgrade packages are primarily intended for professional installation, although some may also suit confident DIY users, particularly MATCH-based systems.

The packages are designed for specific vehicle models and are mostly Plug & Play in design. They are intended primarily for experienced installers or trained professionals.

HELIX packages typically require more advanced tuning skills to unlock their full potential.

Minor modifications may be required depending on the vehicle's exact year and trim. Installation fees are not included in the online product price.

Who This Package Is For
This package is intended for Subaru Forester owners seeking a comprehensive speaker, subwoofer and DSP amplified audio upgrade rather than a speaker-only or subwoofer-only solution.

It upgrades both the front and rear speaker systems, adds dedicated subwoofer reinforcement and introduces DSP-controlled amplification within one vehicle-specific package.

The package is primarily suited to experienced installers and trained automotive audio professionals, particularly where professional DSP setup and tuning are available.

Installation & Tuning Notes
The specified upgrade method is:

No factory amplifier → new amplifier integration

The bundle includes a radio-specific amplifier T-harness as part of the amplifier integration package.

Because the system includes the MATCH UP 6DSP, professional DSP tuning is recommended to optimise the system for the vehicle's acoustic environment.

Minor modifications may be required depending on the vehicle's exact year and trim. Installation and tuning charges are not included in the online product price.
