Why We Love It
  • Powerful, immersive concert-quality sound.
  • Dual class reliability and performance.
  • Scrutinized under rigorous testing.
Main Highlights
  • Concert sound for your car – the JBL Concert A704 power amplifier offers real powerful 280 watt RMS and 1000 watt peak JBL sound experience into your car hifi set and is a great upgrade for your car sound system
  • The high-performance audio amplifier of class AB combines the advantages of class A and B and is equipped with high-quality audio capacitors and power MOSFET's for very high sound quality and is therefore not only powerful, but also very reliable
  • Concert series amplifiers have adjustable high/low pass crossover frequency that allows you to adjust the frequency from 40 Hz to 400 Hz depending on your individual music taste
  • Auto power on: the high level signal input will automatically turn on the amplifier as soon as DC voltage is detected (>2.5V) and the line level signal input turns on the amplifier as soon as a +12V signal is detected.
  • RELIABLE PERFORMANCE: Harman Kardon Amplifiers must go through a rigorous testing process that would destroy an unstable car power amplifier. JBL exposures them deepest cold, high heat and shocks, irradiates them with UV light and lets them run at full power for days.
