Alpine KTA-450 Power Pack Compact 4-Channel Car Amplifier

Alpine KTA-450 Power Pack Compact 4-Channel Car Amplifier will make a significant improvement in your system. This compact 4-channel amplifier puts out 50 watts RMS per channel from a tiny chassis that’ll fit almost anywhere in your vehicle. KTA-450 uses Alpine’s Dynamic Peak Power (DPP) technology to deliver a quick energy boost when needed, virtually doubling the amplifier’s output power on musical peaks.

Award-Winning Power Stack Compatibility

The KTA-450 can mount behind select Alpine 2-DIN mech-less head units, like the iLX-W650, using the included bracket. The recessed harness receptacle allows the wiring to fold between it and the head unit so both products fit in a standard 2-DIN space. This PowerStack design is a 2019 CES Innovation Awards winner  and makes the duo one of the most powerful 2-DIN radios available.

Exclusive Amplifier Technology, Dynamic Peak Power (DPP)

The KTA-450 features Alpine’s exclusive Dynamic Peak Power (DPP). DPP intelligently adjusts the gain to adapt to musical needs. DPP prevents the KTA-450 from clipping by supplying up to double the power for sudden, dynamic sounds. DPP ensures music sounds the way it should at high volumes and boosts the KTA-450 to 400 watts DPP, doubling its power without increasing its size.

Compact Size For Hidden Installation Applications

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.

Simple Installation For Use With Any Radio

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.

Bump up the power

If adding more power makes music sound better, Alpine’s KTA-450 power pack will make a significant improvement in your system. This compact 4-channel amplifier puts out 50 watts RMS per channel from a tiny chassis that’ll fit almost anywhere in your vehicle. KTA-450 uses Alpine’s Dynamic Peak Power (DPP) technology to deliver a quick energy boost when needed, virtually doubling the amplifier’s output power on musical peaks.

PowerStack Installation

Here’s a very cool idea from Alpine — the package includes a PowerStack bracket for mounting the amp in your dash behind Alpine’s shallow chassis iLX-W650 or iLX-407 digital multimedia receiver. The combined depth of receiver and amp is still less than 5″, so it’ll fit in a wide variety of vehicles. The receiver and amp together make a feature-filled and powerful sound system that you’ll enjoy for many miles.

Installation Notes: This power pack will not work in systems with a factory amplifier. Wiring and fuse are not included — 12-gauge power and ground wires and a 20A inline fuse at the battery are required.
