WebA capacitor has two poles: a positive and a negative. They should be clearly marked on the capacitor. The positive connects to the same positive power lead that goes to your sub amp's positive, 12 volt, connection. Use the same gauge wire as the amp uses for its power. This can be accomplished with a distribution block. WebWith that time (the time it takes to get to 1 2 ⋅ V i n ), you can calculate the RC value of the RC circuit. You know R, it's 22K in the circuit above, it's constant. So you can calculate the value of C. Another answer, given that you have a frequency counter, would be to build an oscillator using the 555 timer, and measure the frequency.
