I need help in design a small portable music drawer with three outputs, one for bosses, one for

low and one for intermediate (three speakers), the circuit must amplify its input signal ten times and

be divided with high-pass, low-pass and high-low-pass filters, using the amplifiers, capacitors, diodes and resistors. The desing should have a drawer design in the shape that can work in CAD and an electrical circuit design.

Also need to understant the cost analysis to produce it on a 10,000 production line

units, in this analysis and take into account the total cost of the product the cost of printing the

circuit board (down to screws), labor will be deemed to cost $ 2.00 per unit
