Product Description

Hear the Difference with this Simple Power Upgrade!Add higher output and a more dynamic response with this easy-to-install Alpine head unit Power Pack upgrade. The KTP-445A Power Pack amplifies power output on select 2005 and newer Alpine head units, resulting in up to a 150 percent power increase over the original power from the head unit's built-in amplifier.Overview45 Watts x 4 @ 4Ω/2ΩFor select 2005 and newer Alpine head unitsCompact sizeEasy Installation and FlexibilityCompactCompact 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 ClassIn 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. FrequencyUniquely, the Power Pack distortion actually decreases at higher frequencies, resulting in a clean and clear signal where your ear is most sensitive to distortion. - <0.03% THD+N @ 1W, 1% THD+N @ rated power.

Recently installed an alpine Halo 9 ILX-F409 in my 2013 Civic Si. Since it has the premium audio system it has an external amp from the factory but the sound quality was bad after installing my headunit. I don't need my music to he loud enough to hear from miles away but do enjoy clarity and read about this amp. There's 2 versions, this one is specifically for alpine headunits. Installation couldn't have been easier! Plug and play directly to your head unit using the harnesses the amp and radio came with. Sounds great, can get loud too for such a little amp. I'm currently running Kicker components in the front and coaxials in the rear. Will be adding a kicker hideaway sub as soon as it gets delivered. Great little unit if you're looking to add some oomph to your sound system without needing to be heard from miles away.
