Alpine
Bundle includes an 11-inch floating touchscreen receiver with Apple CarPlay and Android Auto, a compact 4-channel amplifier, plus 6.5-inch and 6x9-inch coaxial speakers
This bundle combines an Alpine iLX-F511 Halo11 multimedia receiver with an 11-inch adjustable floating HD touchscreen, a KTA-450 4-channel power pack amplifier, and R-Series coaxial speakers in 6.5-inch and 6x9-inch sizes. It is built for drivers who want a large touchscreen interface with integrated amplification and matched speakers in a single package. The receiver supports Apple CarPlay, Android Auto, Bluetooth hands-free, HD Radio, and SiriusXM readiness.
The 11-inch floating display sits proud of the dashboard, giving a larger visible area than standard 7-inch or 9-inch fixed panels while fitting many existing openings. The jump is worth it when you need high-resolution 1280 x 720px visuals, 13-band parametric EQ, 6-channel time correction, and three sets of 4V preamp outputs for cleaner signal routing to the included amplifier.
The KTA-450 delivers 50W RMS x 4 at 4 ohms and 45W RMS x 4 at 2 ohms with THD below .2 % and a frequency response of 15Hz - 50kHz, maintaining stable power during extended listening. The R2-S65 and R2-S69 R-Series coaxial speakers are rated for high-resolution audio playback, complementing the receiver’s 24-bit DAC for consistent clarity over long drives.

The iLX-F511 Halo11 uses a single-DIN chassis behind the floating 11-inch touchscreen, so it fits a standard 1-DIN slot with enough depth for the adjustable mount.
Installers frequently forget to connect the supplied power-wire harness to the amplifier’s input before routing signal from the receiver’s 4V preamp outputs.
Inspect the speaker surrounds once a year for drying or cracking; the high-resolution cones are built for long life but rubber surrounds degrade with heat and UV exposure.
