Alpine KTA-450 4-Channel 200 Watt RMS Power Pack Amplifier

Bump up the power

KTA450

The KTA-450 is a very compact 4/2-Channel amplifier, that is mainly designed to be power-stacked with the iLX-W650BT, but can also be used stand-alone in any universal configuration.

Featuring Alpine’s Dynamic Peak Power (DPP) technology, the KTA-450 can add bursts of 100 Watts RMS power when needed.

In combination with the iLX-W650BT, the KTA-450 won the 2019 Innovations Award at CES Show 2019. If you plan to buy an iLX-W650BT, this tiny amplifier will make a significant improvement to your system.

Power-stacked with the iLX-W650BT

Mounted together, the iLX-W650BT and the KTA-450 amplifier measure less than 12,7 cm deep, so they can fit in any standard 2DIN radio dock to create Alpine’s award-winning Power-Stack design. Brackets and included cable harnesses allow for a fast and easy installation. Enjoy the extra sound system boost without the bulk and hassle of a traditional amp.

Power Boost for your Head Unit

Give your iLX-W650BT a sound boost with the 4-Channel KTA-450 Power Pack amplifier, that emits 4 x 50 Watts RMS. Thanks to Alpine’s exclusive Dynamic Peak Power (DDP) technology, this can even increase to 100 Watts DDP per channel during dynamic musical passages.

High-Pass Filters

The KTA-450 features a selectable high-pass filter (60, 80 and 120Hz at 12dB/octave) on front and rear channels. This comes especially handy, if your head unit does not include such sound tuning capabilities.

Versatile & Compact

With built-in preamp and speaker-level inputs (2- or 4-channel input), this tiny amplifier works with many car stereo systems – regardless of OEM or Aftermarket. At only 89mm x 181mm x 36mm it is one of the most compact 4 x 50 Watts RMS amplifiers on the market.
