Alpine iLX-W670-S bundle for car audio upgrades

This bundle combines a 6.75-inch digital multimedia receiver with two pairs of 6.5-inch coaxial speakers and a compact 4-channel power pack amplifier. It suits drivers who want integrated smartphone connectivity and a complete speaker upgrade in one package. The system fits double-DIN dash openings and includes a steering-wheel control adapter. It does not suit buyers who need a single-DIN chassis or a separate subwoofer channel.

40W RMS speakers with 45W RMS per channel amplifier

Each SXE-1726S speaker handles 40W RMS and 220W peak power across a 60Hz to 20kHz frequency response at 4-ohm impedance. The KTA-450 power pack delivers 45W RMS across four channels at both 2-ohm and 4-ohm loads using Class D Dynamic Peak Power technology. This combination provides clean headroom for the included speakers but runs out of power for high-output component sets or subwoofers.

SWC adapter and power pack simplify installation

The bundled steering-wheel control adapter retains factory button functions without extra wiring harnesses. The KTA-450 amplifier measures 7 by 3.5 by 1.25 inches, allowing it to tuck behind the dash or under a seat for a hidden install. Its compact Class D design reduces current draw and heat compared to larger amplifiers. No separate amplifier wiring kit or line-output converter is included.
