Alpine KTA-450 Power Pack Compact 4-channel car amplifier (50w RMS x 4)

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.
