An 11-inch floating touchscreen receiver with Apple CarPlay, Android Auto, Bluetooth, HD Radio, 13-band EQ, time correction and 4V preamp outputs paired
This bundle pairs an 11-inch floating touchscreen receiver with two 6.5-inch coaxial speakers for a complete in-car upgrade. The receiver fits a single-DIN chassis while the speakers mount in standard door locations. Buyers who need a double-DIN chassis or component speaker sets should look elsewhere.
The head unit connects via Apple CarPlay, Android Auto, Bluetooth, HD Radio and SiriusXM, so phone integration and broadcast features depend on those services being available in your region. The 4-volt preamp outputs and 13-band EQ with 6-channel time correction require an external amplifier to be fully utilised. Vehicles without a compatible steering-wheel interface will lose factory controls.
Each speaker handles 100 watts RMS at 4 ohms with a 40-kilohertz frequency response and Hi-Res Audio certification. This power rating and impedance determine whether the speakers match your amplifier or head-unit output. Buyers who need higher RMS power or a different impedance must choose another model.

This bundle pairs the 11-inch floating HD touchscreen with two 6.5-inch R-Series coaxial speakers, giving a large adjustable display that fits a 1-DIN chassis and matched speaker sizing for a cohesive install.
The 13-band EQ lets you shape frequency response across the spectrum while 6-channel time correction aligns arrival times from each speaker position, improving imaging and tonal balance from the driver seat.
The 4V preamp outputs deliver a strong, clean signal to external amplifiers, and the 4-ohm impedance of each R2-S65 speaker matches typical aftermarket amps, allowing up to 100 W RMS per channel.
