Alpine
Bundle includes 11" floating HD touchscreen with Apple CarPlay and Android Auto, 6.5" Hi-Res coaxial speakers, and 45W×4 compact amplifier
This bundle combines an Alpine iLX-F511 Halo11 multimedia receiver with an 11-inch floating HD touchscreen, a pair of Alpine R2-S65 6.5-inch coaxial speakers, and an Alpine KTA-450 4-channel power pack amplifier. It is designed for drivers who want a large display and upgraded sound in a single package. The receiver supports Apple CarPlay, Android Auto, Bluetooth hands-free, and HD Radio.
The KTA-450 amplifier includes a wire harness and universal bracket set for straightforward mounting. Its compact Class D design and power stacking bracket allow placement in tight spaces behind the dash. Installers should verify dashboard depth to accommodate the 11-inch floating screen mechanism and ensure the 4V preamp outputs match the amplifier input sensitivity.
The KTA-450 delivers 50W RMS x 4 at 4 ohms and 45W RMS x 4 at 2 ohms using Dynamic Peak Power technology for consistent output. The R2-S65 speakers handle 300W peak power with reinforced glass fibre cones and a frequency response up to 40kHz for extended high-frequency clarity. The receiver provides a 13-band EQ and time correction for detailed tuning during long listening sessions.

The display should show the Alpine boot logo, then load the home screen with Apple CarPlay and Android Auto icons; touch each icon to confirm the 13-band EQ, time correction and HD Radio menus open without lag.
The box contains the iLX-F511 Halo11 receiver, a pair of R2-S65 6.5-inch coaxial speakers, the KTA-450 4-channel power pack amplifier, wire harness and universal bracket set; you will need speaker wire, RCA cables and a dash kit for your specific vehicle.
The R2-S65 speakers handle 300 W peak; the KTA-450 delivers 50 W RMS × 4 at 4 ohms and 45 W RMS × 4 at 2 ohms, so either rating works — choose 4-ohm wiring for the 50 W RMS figure.
