Alpine
An 11-inch floating HD touchscreen receiver with Apple CarPlay, Android Auto, built-in HD Radio and 13-band parametric EQ, bundled with 6x9-inch component speakers rated at 100 watts RMS.
This package combines an Alpine ILX-F511 Halo11 multimedia receiver with an 11-inch floating HD touchscreen, a KTA-450 four-channel power pack amplifier, R2-S69C 6x9-inch two-way component speakers, and R2-S65 6.5-inch coaxial speakers. It is designed for drivers who want a single-box upgrade covering source, amplification, and full-range sound. The receiver supports Apple CarPlay, Android Auto, built-in HD Radio, and SiriusXM readiness.
The 1280 x 720 display provides a 13-band parametric EQ, six-channel time correction, and 4V preamp outputs for detailed signal shaping during long drives. The KTA-450 power pack uses Dynamic Peak Power technology to maintain clean output when musical peaks extend beyond brief bursts. Component speakers handle 100 watts RMS with a 65Hz to 40kHz response, while coaxial units match the same impedance for consistent thermal performance across all channels.
Verify that your dashboard opening can accommodate the 11-inch adjustable floating display and that wiring harness adapters suit your vehicle's factory connectors. The four-channel amplifier requires adequate ventilation space and a stable 12V supply line for its 450-watt peak rating. Confirm speaker mounting depth for both 6x9-inch and 6.5-inch locations, and ensure crossovers for the component set can be secured within door panels or kick panels.

The compact KTA-450 uses Dynamic Peak Power technology to deliver up to 450 watts of peak output while maintaining efficient current draw from the vehicle's electrical system.
The iLX-F511 mounts in a standard double-DIN opening; its adjustable floating chassis lets you set the 11-inch screen height and angle without custom fabrication.
Yes, both speaker sets present a nominal 4-ohm load that matches typical factory speaker circuits, so they connect directly to the KTA-450 or the head unit's internal amplifier.
