Alpine iLX-507 7" Multimedia Receiver with 2x SXE-1726S 6.5" Coax & KTA-450 Power Pack

7" Multimedia Receiver Bundle

This bundle pairs an Alpine iLX-507 7-inch multimedia receiver with two pairs of Alpine SXE-1726S 6.5-inch coaxial speakers and a KTA-450 4-channel power pack amplifier. The receiver supports wireless Apple CarPlay and Android Auto alongside built-in Bluetooth for hands-free calls and audio streaming. It suits drivers who want a complete audio upgrade with smartphone integration in a single package. Buyers seeking a standalone head unit without speakers or amplification should look elsewhere.

Check Dashboard Space and Wiring

Verify that your dashboard opening can accommodate a 7-inch WXGA display and that you have accessible USB and camera input routing for the receiver. The KTA-450 amplifier measures 7 W x 3.5 H x 1.25 D inches and requires a suitable mounting location such as a glove box or behind the radio. Ensure your vehicle wiring can support front and rear camera inputs plus three pre-out connections. Vehicles without space for the compact amplifier or additional speaker wiring will need alternative planning.

Compact Amplifier and Coaxial Speaker Build

The KTA-450 uses Class D circuitry with DPP technology and includes a Power Stacking bracket for flexible mounting in tight spaces. Installation is simplified with no extra wires required beyond the standard connections. Each SXE-1726S speaker handles 40W RMS and 220W peak power across a 60Hz-20kHz frequency response using Kapton voice coils, ferrite woofers and neodym tweeter magnets. The coaxial design integrates tweeter and woofer in one frame for straightforward door or rear-deck mounting.
