    "description": "KTA-450\nThe KTA-450 is a very compact 4/2-Channel amplifier, that is mainly designed to be power-stacked with the iLX-W650BT, iLX-W690D but can also be used stand-alone in any universal configuration.\nFeaturing Alpine’s Dynamic Peak Power (DPP) technology, the KTA-450 can add bursts of 100 Watts RMS power when needed.\nIn 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, iLX-W690D this tiny amplifier will make a significant improvement to your system.\nRADIO IS NOT INCLUDED\nPower-stacked with the iLX-W650BT & iLX-W690D\nMounted together, the iLX-W650BT , iLX-W690D and the KTA-450 amplifier measure at 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 install. Enjoy the extra sound system boost without the bulk and hassle of a traditional amp.\nPower Boost for your Head Unit\nGive your iLX-W650BT , iLX-W690D 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.\nHigh-Pass Filters\nThe 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.\nVersatile & Compact\nWith 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.\nFEATURES\nInstall\nTerminal Layout: One side\nSmall footprint for easy installation\nConnector terminal (for speaker and power cables)\nGeneral\nAmplifier Type: Class-D (Digital)\nChannel Design: 4/2 Channel (3 Channel configuration not possible)\nDIP Switches\nRCA and Speaker Level Inputs\nCrossover: Adjustable High-Pass Filter (HPF)\nGain Control: Front / Rear Adjustable\nIncluded Power-Stack bracket and screws for back-mount to iLX-W650BT, iLX-W690D\nIncluded cable harness\nSPECIFICATIONS\nRMS Power Ratings\nPer Channel into 2 Ohms, 14.4V (≤1%THD+N): 4 x 45W\nPer Channel into 4 Ohms, 14.4V (≤1%THD+N): 4 x 50W\nBridged, 4 Ohms, 14.4V: 2 x 100W\nDPP (Dynamic Peak Power) Power Ratings\nPer Channel into 2 Ohms, 14.4V (≤1%THD+N): 4 x 100W\nPer Channel into 4 Ohms, 14.4V (≤1%THD+N): 4 x 100W\nSound Tuning\nCrossover: Selectable HPF: 60, 80, 120Hz (-12dB/oct) on front and rear channels\nGeneral\nPower Requirements: 14.4 V.DC (9 - 16 V allowable)\nFrequency Response (+0/ -3dB: 1W into 4 Ohms): 15Hz – 50kHz\nTHD+N (@ 10W into 4 Ohms): <0.2%\nS/N Ratio: AES-17, Ref: 1W into 4 Ohms: >85dB\nWeight: 0.6kg\nDimensions\nWidth: 89mm\nHeight: 36mm (39mm with attached universal bracket)\nLength: 181mm (198mm with attached universal bracket)",
