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.
