I was MASSIVELY over tweeted. Example 1: Four 8 ohm speakers in parallel: 8 divided by 4 = 2 ohms. *To compute the net impedance of a speaker and a resistor in series, draw a line, say, 6 cm long for a 6 ohm speaker and at the end draw a 2 cm line at right angles to stand for the 2 ohm resistor. That is the big difference between the two speakers. A wide variety of resistor 8 ohm options are available to you, such as other. You can put a resistor in series or just run two speakers in series to hit 6 ohm/ 9 ohm with three speakers. The factory put 8 ohm speakers in the dash so that the dash speakers would not overpower the door speakers due to their placement (in your face). The net impedance is roughly equal to the length of a straight line (the diagonal) from the start to the finish. Anytime you mismatch a load it’s potentially bad for the amp, but there’s “bad” and “really bad” I suppose. Only 18 left in stock - order soon. That way if you’re using speaker crossovers, which are designed for a specific speaker Ohms load, the sound won’t be affected – only the volume. Click & Collect. IN this case, I was trying to match impedances and come to a correct load. Problems occur when the impedance of the load causes the amplifier to try to . simulate this circuit – Schematic created using CircuitLab.
