Details about the Alpine KTA-450
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.
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 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
