The Alpine KTP-445U adds more dynamic response and higher output to a system. On top of this, it is easy to install. The universal power pack amplifies factory or aftermarket installed head unit power output. It increases the power by 150% of the unit’s original power.

KTP-445U’s compact size allows it to fit in places where other amplifiers will not fit. In most vehicle dashes, it fits right behind the main unit. Auto-sensing-speaker and RCA connectors come with the power pack. These connectors are flexible in nature, which also helps fit the power pack into a limited space.

Highly Configurable

Another benefit is that this power pack is configurable to specific needs. The pack’s bottom panel contains input options that accommodate RCA inputs of 0.2 V to 4V and speaker levels of 0.5V to 10V. One can select either 2-channel or 4-channel adjustments to control the source inputs. This removes having to use Y-adapters.
