Alpine
An 11-inch floating HD touchscreen receiver with Apple CarPlay, Android Auto, Bluetooth, built-in HD Radio, 13-band EQ and 4V pre-outs.
This bundle combines an Alpine iLX-F511 Halo11 receiver with two pairs of coaxial speakers and a compact four-channel amplifier. It is designed for drivers who want a large touchscreen interface and a complete speaker upgrade in one package. The floating 11-inch display sits above the dashboard for clear visibility. Buyers who need a double-DIN chassis or built-in navigation should look elsewhere.
The receiver’s 11-inch WXGA touchscreen mounts on an adjustable hinge so it can be tilted for optimal viewing angle. Two pairs of 2-way coaxial speakers are included: 6.5-inch units rated at 40W RMS and 6x9-inch units rated at 45W RMS. The KTA-450 power pack delivers 50W RMS per channel at four ohms and includes a power output harness with mounting brackets for straightforward installation. Installers without spare wiring harnesses or dash kits will need to source those separately.
A 13-band graphic equaliser and six-channel time correction allow detailed sound tuning from the receiver menu. The KTA-450 amplifier uses DPP technology to produce its rated output without requiring a separate heavy-gauge power wire run. Three camera inputs, two USB ports and four-volt preamp outputs handle media and safety connections. Users seeking built-in HD Radio streaming apps or wireless CarPlay will not find those features here.

The 11-inch floating touchscreen uses a WXGA panel; that standard sets the practical resolution ceiling for the receiver's interface and camera feeds.
The 6.5-inch coaxials require standard 6.5-inch door cut-outs, while the 6x9-inch coaxials need 6x9-inch rear-deck openings; both pairs mount with their included hardware.
The KTA-450 connects via its supplied power-output harness and mounts with the included brackets; the step often missed is securing the amplifier without running extra power-supply wires, as DPP technology draws power through the harness.
