Please Read Before Purchasing
This vehicle-specific upgrade package is primarily intended for professional installation, although some vehicle-specific systems may also suit confident and experienced DIY installers.

The system is mostly Plug & Play in design, but HELIX-based packages typically require advanced installation and tuning knowledge. Minor modifications may also be required depending on the vehicle's exact year and trim.

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

Who This Package Is For
This package is designed for Toyota Land Cruiser Prado J250 owners with the JBL audio system who want to upgrade the complete front and rear speaker system together with amplification and DSP processing.

It is particularly suited to customers looking for a substantial speaker-system improvement rather than a simple front speaker replacement, with professional DSP tuning available to optimise the complete system.

Installation & Tuning Notes
The package includes a radio-specific amplifier T-harness together with the DSP amplifier and vehicle-specific speaker mounting hardware.

Professional DSP tuning is recommended to correctly configure the multi-way front stage, rear speakers and amplifier processing for the vehicle's acoustic environment.

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

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