Shallow-Mount 7-Inch Receiver

The Alpine iLX-407 is a 7-inch multimedia receiver with a shallow chassis designed for dash openings where depth is limited. It delivers Apple CarPlay, Android Auto, Bluetooth, SiriusXM-Ready and HD Radio functions. The bundle pairs this head unit with SXE-1751S component speakers, SXE-1726S coaxial speakers and a KTA-450 power pack amplifier. It suits drivers upgrading a factory stereo without cutting the dashboard.

Thermal and Power Behaviour

The KTA-450 power pack uses Dynamic Peak Power technology and draws energy from the existing vehicle wiring, so no new power-supply cable is required. Its compact 7 by 3.5 by 1.25 inch frame fits behind the receiver, keeping heat confined to a small area. The four-channel design outputs 50W RMS per channel at 4 ohms and 45W RMS at 2 ohms. Normal operation stays within the vehicle's standard electrical capacity.

Bundled Hardware Impact

The SXE-1751S component set brings 45W RMS and 280W peak handling with a ferrite woofer and neodymium tweeter for separated imaging. The SXE-1726S coaxial pair adds 40W RMS and 220W peak using a Kapton voice coil and ferrite-neodymium magnet structure. Together they cover 60Hz to 20kHz across four channels. Buyers needing more than four amplified channels or higher continuous output per channel will need additional amplification.

Questions about this item

How do I fit the iLX-407 shallow chassis and where does the KTA-450 Power Pack mount without running a new power wire?

The iLX-407 uses a shallow 2-6/16" depth and included mounting bracket; the KTA-450 measures 7"W x 3.5"H x 1.25"D and draws power through the existing harness so no extra supply wire is required.

Which speaker components will need attention first and what are their power ratings?

The SXE-1751S component speakers handle 45W RMS and 280W peak; the SXE-1726S coaxial speakers handle 40W RMS and 220W peak — both at 4 ohms. Surrounds and voice coils are the typical wear items.

At what point does the KTA-450 amplifier hit its thermal limit during extended playback?

The KTA-450 delivers 50W RMS x 4 at 4 ohms using Dynamic Peak Power technology; sustained output at that level will eventually trigger thermal protection.
