Compact size lets the KTP-445U fit where most amplifiers won’t. The KTP-445U comes equipped with the RCA and Auto-Sensing-Speaker level connectors and it fits behind the head unit in the dash of most vehicles. It's small and compact at only 7-7/16” x 1-1/2” x 2-1/2”. The size and flexible wires make the Power Pack an easy choice to save space.
INDEPENDENT FILTERS FOR REAR & FRONT INPUTS
High-Pass selectable switches for Front & Rear allow frequency filtering for a wide variety of speakers. Choose from full range to selectable range: 60Hz, 80Hz or 120Hz to fine-tune your crossover points.
Need configurable options for Speaker-Level or RCA inputs to the Power Pack? On the bottom panel of the Power Pack there are selectable input options to accommodate Speaker-Level (0.5V-10V) or RCA (0.2V – 4V) inputs. Selectable 2 Channel and 4 Channel options give you the control to determine source inputs, and can eliminate the need for Y-adapters.
ACCESSIBLE FRONT & REAR GAINS
The Power Pack provides simple variable gain controls on the end panel for flexibility and a wide variety of system applications.
BEST SIGNAL-TO-NOISE CONTENDER IN ITS CLASS
In order to ensure that Alpine sound quality is heard at your ears, 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.

These are superb little amps. Very small but pack some power. Great for an upgrade from stock radio to give better sound and more power.
Great little unit, fits nicely under the dash and provides a great punch to my music. This is no tube amp, but for the price, you get a decent quality sound. Most people wont need much more than this little unit.
