But if you want high-performance audio, consider this SONY external amplifier for car radios. This 4-channel amplifier uses carefully selected audio capacitors, output transistors and coil dampers to achieve realistic and clear sound reproduction. Improve your listening experience with a clear high-frequency range, available in a maximum output of 4 x 70 W with 4-ohm speakers or up to 4 × 250 with 2-ohm.Key featuresClear and powerful audio for better listening experienceHigh-quality product made from carefully selected componentsBroadband amplification (5 Hz to 50 kHz)Low pass filter (LPF) for subwooferHigh pass filter (HPF)Design optimised for coolingAutomatic temperature control prevents shutdownAlways onThe amplifier’s construction was designed to provide the best air circulation needed for cooling. Despite its power, the amplifier maintains a low temperature and can reproduce stable and powerful audio without any distortion. And if the critically important components do begin to overheat, the automatic temperature monitoring simply reduces the amplifier’s performance instead of shutting it down entirely. You can blast your sound system at the maximum volume even on a hot summer day and know that nothing will interrupt your musical experience.Specifications:Amplifier:Channel configuration: 4ch; 2ch; 1chLow Pass Filter: 80 HzSlope: Low Pass Filter 18 dB/octave (80 Hz)Slope: High Pass Filter 12 dB/octave (80 Hz)Rated output power (RMS 20 to 20 000 Hz):Max. channel config. at 4 ohm (W) / THD (%): 4 x 70 W / 1.0%Max. channel config. at 2 ohm (W) /THD (%): 4 x 85 W / 1.0%Maximum power output:Max. channel power config. at 4 ohm: 4 x 170 WMax. channel config. at 4 ohm BTL: 2 x 500 WMax. channel power config. at 2 ohm: 4 x 210 WGeneral:Frequency response: 5-50 kHzTolerance: +0 / -3 dBSignal to noise ratio: 100 dBTotal harm. distortion at 1 kHz (%): 0.05%Details:CEA output power: 4 x 70 WCEA signal/noise ratio: 93 dBAMOSFET power supplyLine In: input sensitivity 0.3-6Gold-plated connectorsCurrent drain (A) - rated output power at 4 ohm: 36Subsonic high pass filter: 12 dB/octaveWeight:2.7 kg
