Alpine iLX-407 Bundle Overview

The Alpine iLX-407 bundle combines a shallow-chassis 7-inch multimedia receiver with Apple CarPlay and Android Auto, a pair of R2-S65 6.5-inch coaxial speakers, and the KTA-450 4-channel power pack amplifier. It is designed for drivers who want a complete audio upgrade with smartphone integration and amplified sound in a single package. The receiver features an anti-glare touchscreen with WVGA 800 x 480px resolution.

Installation And Compatibility Notes

The iLX-407 includes a mounting bracket, wiring harness, USB extension cable, and microphone for a straightforward single-DIN installation with a 2-6/16-inch chassis depth. The KTA-450 Power Pack measures 7 x 3.5 x 1.25 inches and comes with input/output/power wire harnesses and a universal bracket set. Builders lacking Maestro-compatible steering-wheel interfaces or vehicles without adequate dash clearance for the 7-inch screen height should verify fitment before purchase.

Sustained Power And Thermal Behaviour

The KTA-450 delivers 50W RMS x 4 at 4-Ohm and 14.4V using a Class D circuit with Dynamic Peak Power technology, while the R2-S65 speakers handle 100W RMS and 300W peak with 88dB sensitivity. The PowerStack-capable design allows the amplifier to stack directly behind the receiver, sharing a compact footprint that aids heat dissipation during extended listening sessions. Continuous high-volume playback remains stable within the rated 45W RMS x 4 power pack specification.

Questions about this item

How do I confirm the 7-inch WVGA 800 x 480 touchscreen and Apple CarPlay are active after installation?

Power the vehicle, verify the Alpine logo appears, then connect an iPhone via USB or Android phone wirelessly; the CarPlay or Android Auto home screen should launch on the 800 x 480 display within seconds.

Which components are included in the bundle and what must I source separately?

The box contains the iLX-407 receiver, mounting bracket, wiring harness, USB extension cable, microphone, quick guide, installation manual, a pair of R2-S65 6.5-inch coaxial speakers, and the KTA-450 power pack with its own wire harness and universal bracket set. Speaker wire, RCA cables, and dash kit are not included.

Should I choose the 45 W RMS or 50 W RMS amplifier rating for my system?

The KTA-450 delivers 45 W RMS x 4 into 4 ohms per its CTA-2006 rating; the 50 W RMS x 4 figure is measured at 14.4 V. Use the 45 W RMS number for typical vehicle voltage and speaker matching.
