The KTP-445U 4/2-Channel Power Pack Amplifier produces big subwoofer power in a small space.

This 4-channel-power amplifier provides an easy update path to add more bass to a sound system in vehicles that don't normally have the room for a traditional amplifier.

With the compact, Power Pack design, the amplifier can fit in hidden areas, like a glove box, under a seat, or mounted behind a receiver to optimize power and space in the vehicle.

The KTP-445U provides up to 150% power increase over the original power from the head unit's built-in amplifier.

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.

The Power Pack provides simple variable gain controls on the end panel for flexibility and a wide variety of system applications.
