ACTIVE CAR SUBWOOFER WITH A POWER OF 70 W - SELF-ASSEMBLY KIT

Producer: AVT

It is an amplifier with very good parameters for the subwoofer. The system is powered by battery voltage (14.4V). In addition to the power amplifier, it also contains an active filter with a switchable characteristic and differential input stages, allowing the use of a signal from any source. Thanks to the use of the TDA1562Q integrated amplifier, working in the H-class, it achieves an unbelievably high power output of 70W at a load of 4W at a 14.4V power supply.

Basic parameters:

  • Working voltage of 8 ... 18V
  • Permissible supply voltage 0 ... 30V (temporarily up to 45V)
  • Quiescent current typ. 110mA, max 150mA
  • Strengthening 26dB (20x)
  • Maximum power (14.4V, 4Ω, THD? 10%) typ.70W
  • Maximum power (14.4V, 4Ω, THD ± 0.5%) typ. 55W
  • Maximum continuous output current 8A, peak 10A
  • Nonlinear distortion (14.4V, 4Ω, 20W) typ. 0.06%
  • Upper limit frequency> 20kHz
  • in the set a printed circuit board, a set of elements and documentation
