The KTP-445A connects to any 2005 and newer Alpine headunit that uses a black power harness. It will not work with the CDE-100 or IVE-W530 receiver.
KTP-445A Power Pack and harnesses
Want a simple way to kick up the power of your Alpine receiver? Alpine's "Power Pack" amplifier increases your receiver's power output to 45 watts RMS power by 4 channels — plenty of power to drive high-performance speakers or keep up with a big subwoofer amplifier.
Installation Note: We recommend running a dedicated constant power wire to the battery for optimal performance from this Alpine amp — we offer an inexpensive wiring kit for this installation. This high-powered amp won't work in systems where an outboard factory amplifier is still active.
