Mosfet stereo amplifier part 5

Simple mosfet amp. Bass boost. With spacial enhancement, rear chanel delay. More speakers more volume. More battery, bigger speaker power. Big heatsink. 4 Irfz44n 4 100 ohm resistors 2 22mf capacitors 2 200mf capacitors 2 1000mf caps for filter and bass boost. 2 trimmer pots for input, to prevent clipping. 1 headphone connector or Bluetooth module. 1 or more battery, rechargeable lithium ion type. Lights simulate speakers. If more power is needed. 12 volt car battery will work. I use a 5 watt Bluetooth board as input. Rear chanel has a cutoff frequency. Third row is a dual coil subwoofer. This helps to add bass boost by limited high Freq. 10 mh - 16khz 20 mh - 8khz 30 mh - 5khz 40 mh - 4khz 50 mh - 3khz ( top of voice Freq. ) 100mh - 1.5khz 200mh - 800hz ( top of Sub Freq. ) 500mh - 500hz 10 mh - 50mh use open air coil to allow the delay. Above 50mh a core will limit the size per cutoff freq. Working with speakers is almost magical like doing antenna design. Every situation is a one of a kind. Enjoy and do new things it's aways fun. Remember when faced with a choice of taking the horses, money and the girls, you can give up the horses.
