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.

Configurable Inputs

  • 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, they'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. - < 0.03% THD+N @ 1W, 1% THD+N @ rated power.

I asking about the Alpine KTP- 445U universal power pack. It says in store purchase only, I live in northern mn. There are no stores even remotely close to me. How do I purchase this product?

  Thanks for your question. The manufacturer does not allow us to sell this product online, as they only want it being sold through installation shops (like our showrooms in the Philadelphia area). I would recommend contacting Alpine customer service directly for assistance in making arrangements to get this. Thank you!
