Alpine KTP-445A Head Unit Power Pack

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.\nWith 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.\nThe KTP-445A includes direct plug-in connectors that work with select 2005+Alpine head units, resulting in up to 150% power increase over the original power from the head unit's built-in amplifier.
