Alpine iLX-W670-S bundle for car audio upgrades
This package combines the Alpine iLX-W670-S Digital Multimedia Receiver with two speaker pairs and a power pack amplifier. It is built for drivers who want a single-box solution to replace a factory stereo and all four door speakers. Buyers who need a standalone subwoofer amplifier or a multi-zone DSP will not find those functions here.
Thermals noise and power draw in normal use
The KTA-450 Power Pack delivers 450 W peak power through four channels while fitting behind the receiver. The SXE-1751S component speakers handle 45 W RMS and 280 W peak with a 60 Hz to 20 kHz response. The SXE-1726S coaxial speakers handle 40 W RMS and 220 W peak over the same frequency range.
What the bundled accessories actually change
The bundle adds a 6.75 inch touchscreen with Apple CarPlay and Android Auto, Bluetooth hands-free, SiriusXM-Ready support and Lighting Link for compatible Alpine subwoofers. Component speakers use a ferrite woofer, neodym tweeter and Kapton voice coil. Coaxial speakers use a ferrite woofer magnet, neodym tweeter magnet and Kapton voice coil.

Questions about this item
How do I install the KTA-450 4-Channel Power Pack Amplifier and what step is commonly missed?
Connect the KTA-450 directly to the iLX-W670-S receiver's speaker outputs using the supplied harness, then secure the compact amplifier chassis behind the dash; the step often missed is routing the power lead to the battery with an inline fuse.
What maintenance or replacement will the SXE-1751S and SXE-1726S speakers need later?
The SXE-1751S component speakers and SXE-1726S coaxial speakers use ferrite woofers with Kapton voice coils and neodym tweeters; no scheduled maintenance is required, but a tweeter or crossover can be replaced individually if damaged.
What limit appears first on the KTA-450 amplifier during sustained high-volume use?
The KTA-450 Power Pack Amplifier delivers 45 watts RMS per channel; thermal protection will engage before clipping if the 450-watt peak demand is held continuously.
