The Toyota GR Supra (2019-) JBL - Underseat Subwoofer Upgrade Kit | For Amplified Systems is a vehicle-specific low-frequency upgrade designed for the Toyota GR Supra from 2019 with the JBL audio system. The package replaces the under-seat woofer system with a pair of HELIX COMPOSE Ci5 S200FM-S2 8" FlexMount woofers and two vehicle-specific FlexMount subwoofer adapters.
Each HELIX Ci5 S200FM-S2 uses a 1 × 2Ω voice coil, handles 200 W RMS / 400 W maximum, and features an ultra-shallow 47 mm installation depth. The hybrid woofer design operates from 25 Hz to 500 Hz, making it suitable for low-frequency and mid-bass reproduction in restricted factory mounting locations.
This is a subwoofer upgrade kit only. It does not include an amplifier or DSP and is intended for vehicles already using a suitable amplified system.
Key Benefits
- Twin 8" under-seat woofer upgrade for the Toyota GR Supra JBL system.
- HELIX COMPOSE Ci5 S200FM-S2 woofers provide 200 W RMS power handling per driver.
- 2Ω impedance per woofer suits amplified system applications.
- 47 mm ultra-shallow installation depth supports integration into restricted factory mounting locations.
- FlexMount200 technology uses dedicated adapter rings to integrate the woofers into the original mounting positions.
- ±7.8 mm linear excursion supports strong low-frequency output from the shallow driver architecture.
- 25 Hz – 500 Hz frequency response allows the drivers to operate across sub-bass and mid-bass frequencies.
- Dedicated FlexMount subwoofer adapters are included for the vehicle-specific installation.
Please Read Before Purchasing
This vehicle-specific upgrade package is primarily intended for professional installation, although experienced and confident DIY installers may also be able to complete suitable Plug & Play upgrades.
The kit is designed for an amplified audio system and does not include an amplifier. The existing amplifier or upgraded amplifier must therefore be suitable for the replacement 2Ω under-seat woofers.
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 designed for Toyota GR Supra JBL owners who already have an amplified audio system and want to improve the vehicle's under-seat bass and mid-bass performance without replacing the complete sound system.
It is particularly suitable for customers upgrading an existing amplified system or building the under-seat woofer stage as part of a larger audio upgrade.
Professional installation is recommended to confirm amplifier compatibility and correct vehicle fitment.
Installation & Tuning Notes
This kit includes the replacement under-seat woofers and their required FlexMount adapters.
Because the package contains no amplifier and no built-in DSP, amplifier installation or DSP calibration is not part of the supplied kit.
The HELIX Ci5 S200FM-S2 woofers use 1 × 2Ω voice coils, so the existing or upgraded amplifier configuration should be suitable for the replacement drivers.
Minor modifications may be required depending on the exact vehicle year and trim. Installation charges are separate from the online product price.
