How do I make the power of 2x145watts usable on my jbl gto 75.2? At a voltage of 14,4V as far as I know, an auto akku usually 12v (HABE A VW POLO 9n) thanks in advance mfg snigers jbl gto75.2 • 2 x 97 Watt RMS at 4 Ohm, distortion factor = 1% (THD+N) • signal noise distance: 82 dBA (referred to 1 Watt at 4 Ohm) • 2 x 145 Watt RMS at 2 Ohm at a voltage of 14,4 Volt; distortion factor = 1% (THD+N) • 1 x 290 Watt RMS at 4 Ohm at a voltage 14.4 volts; distortion factor = 1% (THD+N) • Dynamic power: 190 watts at 2 ohms • Effective attenuation factor: 6.39 at 4 ohms • Frequency range: 10 Hz – 90 kHz (-3 dB) • Maximum input voltage (at speaker terminals): 5.5 volts • Maximum input voltage (at the Cinch sockets): 230 mV • Frequency dependent output attenuation: 0.098 dB at 4 ohms • Built-in electronic crossover: 12 dBLow pass filter, adjustable takeover frequency • Two preamplifier outputs with vol • Inputs via loudspeaker terminals or Cinch sockets • Dimensions (L x W x H): 295 x 313 x 60mm
