Alpine iLX-407 7-Inch Receiver Bundle with R2-S69 6x9" Speakers and KTA-450 Power Pack

Alpine iLX-407 Bundle Overview

This bundle combines a shallow-chassis 7-inch multimedia receiver with Apple CarPlay and Android Auto, two 6x9-inch coaxial speakers, and a compact four-channel power pack. It is designed for drivers who want a complete audio upgrade without replacing factory wiring or adding a large external amplifier. The package includes all necessary harnesses, a microphone, and mounting hardware for a straightforward installation. Buyers who need a double-DIN screen size or built-in navigation should look elsewhere.

Thermals and Power Draw

The KTA-450 power pack delivers 45 watts RMS per channel at both 2-ohm and 4-ohm loads, providing clean power without the heat footprint of a traditional full-size amplifier. Its compact aluminium chassis dissipates heat efficiently, allowing it to be tucked behind the dash or under a seat where airflow is limited. The receiver's shallow 2-inch depth further reduces thermal load in tight cavities. No fan noise is introduced because the amplifier operates passively.

Build Quality and Connectivity

The receiver uses a 2-DIN touchscreen display with a 7 by 4 by 2-6/16 inch chassis that fits many vehicles without major dash modification. Speakers feature glass-fibre reinforced cones, composite baskets, and high-pass crossover networks for durability and reduced distortion up to 40 kilohertz. Connectivity includes Bluetooth, HD Radio, SiriusXM readiness, an HDMI input, USB, and a dedicated camera harness for adding a reverse camera. Maestro compatibility retains steering-wheel controls and vehicle data in supported cars.
