Alpine . KTA-450

Alpine KTA-450 4-Channel Power Pack Amplifier with PowerStack Capability The next generation of Power Pack is here! The compact KTA-450 Power Pack Amplifier utilizes Alpine’s exclusive DPP technology for a big power boost in a small space. The KTA-450 measures just 7” W x 3.5” H x 1.25” D. For vehicles that do not have the space for a traditional amplifier, the KTA-450’s small size allows it to be tucked away in hidden areas such as in the glove box or behind the radio. It could even be used in a motorcycle’s saddlebag or on a boat. No Extra Wires! Thanks to the efficient power needs of the DPP technology, the KTA-450 does not require a new power supply wire at the battery, so installation is fast using the supplied radio power wires. In addition, the KTA-450 uses a 22-pin power harness with a recessed design on one side, so the cables can be tucked-in for a cleaner, less-bulky installation.
