160Ω resistor included with speaker
The speakers available to use with it are from a stereo which says 4 ohms under the wire tabs. Not sure if that means each or both are 4 ohms. This gets extremely loud for the small apartment I'm in. Not even an eighth of a turn and it's way too loud. Would a resistor in the speaker lines be a good way to handle this, and what value would you recommend given the stats above? Not a shared ground. Adding resistors in series with the speakers as you suggest would work, but is not a good idea, for two reasons:.
So it means that, depending on the frequency, the speaker will see a different RMS voltage across it the frequency response will be less homogeneous. It would make more sense to attenuate the input to the amp, using another pot, or just a fixed resistor divider actually two, one per channel. Adjust R2 to get the level you need the lower the value, the lower the volume.
Here, with a 4. If you put a 1. Best Answer. Here is what you can do, for each channel: simulate this circuit — Schematic created using CircuitLab Adjust R2 to get the level you need the lower the value, the lower the volume. Related Question.

Electronic – Volume reducing resistor in speaker lines
In late a plug-in was added for making speaker impedance measurements. This post takes a look at additional hardware requirements to be aware of and the impact of those requirements on impedance accuracy. First, take a look at the topology for measuring speaker impedance in the diagram below. Let's recap how the measurement works: The left channel measures the voltage across the speaker and only the speaker differentially, and the right channel measures the voltage across a sense resistor in series with the speaker. From the second measurement, we can learn the current flowing in the resistor and speaker, and using a complex division with the speaker voltage, the impedance and phase of the speaker can be learned. Above we are specifying the sense resistor value, the desired output level for the chirp, any external gain that might be present, how much smoothing we'd like, and then a few options related to phase and calculations. The key to this topology working is the CMRR, or common mode rejection ratio of the QA when measuring the sense resistor voltage. That is, if you apply an identical sine wave to both inputs of the QA left channel, you should see no signal at the sine frequency. But in fact that's not the case: Every differential circuit has a CMRR short of ideal and it's usually due to resistor variations between the channels. In the QA, a representative set of plots were made with the attenuator on and off for both the left and right channels at both Hz and 1 kHz.

CCR2.2K-.5 Resistor
A lot has been written about replacement of speaker xover resistors including adding resistors to film caps to more closely match the ESR of the original NPE caps. I thought it would be nice to have all the questions and answers to resistors in one thread. Can you get by with 20 watt rated resistors? Re: adding resistor to a film cap when replacing NPEs. For contemporary NPE's, use 0.

This dramatically decreases distortion when the radio is connected to an amplifier instead of being connected directly to the speakers. We sell plug and play connectors with load resistors already in line with RCAs, but you can also make your own. An important step that many people miss is not putting resistors on the rear speaker output of the radio. Even if you do not use the rear speaker output, you must add load resistors in order to keep the radio from distorting. You will need a 10 watt 47 ohm resistor for each channel one for left and one for right, both front and rear. Solder the two resistors between the positive and the negative wires of the rear speaker output plug.

While seemingly new in concept, the purpose of these resistors is simple. Most modern car audio amplifiers, especially those installed by a vehicle manufacturer on an assembly line, use Class-D output circuitry to provide a balance of sound quality and amplifier efficiency. Automakers are fanatical about reducing fuel consumption. The output of the filter is the original audio signal.
