COMPACT
Compact size lets the KTP-445A fit where most amplifiers won’t. The KTP-445A comes equipped with direct plug-in connectors foselect 2005 and neweAlpine 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 PowePack an easy choice to save space.
BEST SIGNAL-TO-NOISE CONTENDER IN ITS CLASS
In ordeto 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 PowePack boasts 1 Watt Signal-to-Noise Ratio of 82dB obetter.
Total Harmonic Distortion (THD+N) vs. Frequency
Uniquely, the PowePack distortion actually decreases at highefrequencies, resulting in a clean and cleasignal where youeais most sensitive to distortion. – <0.03% THD+N @ 1W, 1% THD+N @ rated power.
