Alpine KTP-445A 4-Channel Head Unit Power Pack Amplifier

Upgrade Your Head Unit Power with a Alpine KTP-445A amplifier. Add higher output and more dynamic response with this easy-to-install head unit power upgrade. The KTP-445 amplifies the head unit power output, resulting in a 150 percent power increase over the original power from the head units built-in amplifier. The Alpine KTP-445 connects any 2005 and newer Alpine head unit that has a black power harness. *Contact your local authorized Alpine retailer to confirm compatibility.

More power for your Alpine receiver

Want a simple way to kick up the power of your Alpine receiver? Alpine’s “Power Pack” amplifier increases your Alpine 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.

Easy Installation and Set Up

The KTP-445 fits behind the head unit in the dash of most vehicles. It’s small and compact at only 6″ x 2″ x 1-1/8″. Its plug-and-play installation keeps it simple, without requiring additional wiring or special tuning. A high/low gain switch allows for proper gain settings, whether or not a subwoofer is part of the system.

Compact

Compact size lets the KTP-445A fit where most amplifiers won’t. The KTP-445A comes equipped with direct plug-in connectors for select 2005 and newer Alpine head units and it fits behind the dash of most vehicles. It’s small and compact at only 7-7/16” x 1-1/2” x 2-1/2”. Its size and flexible wires make the Power Pack an easy choice to save space.

Best Signal-to-Noise Contender In Its Class

In order to ensure that Alpine sound quality is heard, we’ve created a platform that offers an unbelievably low noise floor, taking extra care to ensure a clean signal path, with no extraneous interference. The end result: The Power Pack boasts 1 Watt Signal-to-Noise Ratio of 82dB or better.

Total Harmonic Distortion (THD+N) vs. Frequency

Uniquely, the Power Pack distortion actually decreases at higher frequencies, resulting in a clean and clear signal where your ear is most sensitive to distortion. – less than 0.03% THD+N @ 1W, 1% THD+N @ rated power.
