About the Alpine KTP-445 Power Pack
The KTP-445 connects to any 2005 and newer Alpine headunit that uses a black power harness. It will not work with the CDE-100 receiver.
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. Best of all, you install the compact Power Pack by plugging it directly into your Alpine receiver's wire harness — no extra wires to run, and no other connections needed.
Note: The KTP-445 Power Pack won't work in systems where an outboard factory amplifier is still active. You'll have to bypass the factory amp if you want to upgrade your power with the KTP-445. Please contact an Advisor at 1-888-955-6000 to check compatibility if you have any questions.
What's in the box:
- Head Unit Power Pack (45W x 4 RMS) with attached 38" harness terminated by a male Alpine connector on one end and an attached 29" harness terminated by a female Alpine connector on other end

Overview: The Alpine KTP-445 Head Unit Power Pack is an easy-to-install power upgrade amplifier that allows you to add higher output and more dynamic response to your Alpine headunit. The KTP-445 amplifies your Alpine headunit's power output, resulting in a 150 percent power increase over the original power from the headunit's built-in amplifier.
Compatibility: The KTP-445 connects to any 2005 and newer Alpine headunit that has a black power harness. Please check with your Crutchfield Product Advisor to confirm compatibility.
Installation: Since the KTP-445 is small and compact, it installs behind your Alpine headunit in the dash of most vehicles. Its plug-and-play connections keep it simple, without requiring additional wiring or special tuning. The male harness connects to the rear plug on your Alpine headunit while the female harness plugs into your Alpine headunit's harness (included with your Alpine headunit). Then connect the wires from the Alpine headunit's harness to your factory harness adapter (sold separately).
Note: The factory radio circuit needs to be a minimum of 15A. If it is not, a separate power and ground will need to be installed for the KTP-445.
Controls: A high/low gain switch on the bottom of the amplifier allows for proper gain settings, whether or not a subwoofer is part of the system.
