Alpine KTA-450 is a compact 4/2 channel amplifier and can be used both to boost the audio from aftermarket sources but also to boost the audio from original sources, thanks to its convenient automatic turn-on.

Using Alpine Dynamic Peak Power (DPP) technology, the KTA-450 can increase power up to 100 Watts RMS.

The KTA-450 has a selectable high-pass filter (60, 80 and 120Hz at 12dB/octave) for the front and rear channels. This greatly simplifies installation in cars where these controls are not available.

Thanks to the ability to handle PRE level input signals and also high power signals (speaker level) in either 2 or 4 channels, the Alpine KTA-450 amplifier will work with most aftermarket radios on the market, but also with most OEM radios. Its reduced dimensions: 89mm x 181mm x 36mm, make it one of the most compact amplifiers on the market.
