This is a circuit diagram of power amplifier circuit diagram for subwoofer. Where necessary the ability to connect the air, the addition of transistors recommended 4 achievement, active in such a way as Q9, Q10, Q11 and Q12, and applications of 0.33 ohm emitter resistors. Ability continuously into 8 ohms is about more than 150W (250W for ± 70V supplies), and can be adjusted after the transistor is added to the abundant capacity into 8 ohms number all day, every day. Added transistors alone naked if you appetite to engage into 4 ohms at best accumulated stress. Do not anticipate the application of food for ± 70V, Here is a schematic drawing:

In the picture above is accepted analytic design. Internal connections are provided to the SIM (published abroad in the Project Pages), and clarification given to the protection of RF (R1, C2). Which states that bipolar disorder is through 4.7uF cap, because it gives a lot of capacitance in the size of the baby. Because the impedance, little or no complete humiliation of being seen. A polyester hat can be adjusted if you adopt – 1uF assuming a nominal impedance of 22k will fit a 7.2Hz-3dB abundance, really low abundance for each sub.
