There are a couple of reasons why it is critical to match the speaker load with the output impedance of your amplifier: You will benefit from the maximum transfer of power, for example. The other reason is that if you use the wrong load, you can sometimes put your amp in a dangerous situation. Even if you are unsure, it is safer to use a higher impedance to protect the amplifier.
If you have a multi-speaker system, the overall impedance is determined by how your speakers are connected. Connect the white cable to the + terminal lug on the speaker and the black cable to the – terminal lug on the speaker to complete the circuit. There is a 1/4″ jack on many guitar amplifiers labelled “speaker out”.
In addition, information on the lowest impedance load that the guitar amplifier can safely handle is frequently printed on the amplifier someplace near this input jack. Go through the article for a better understanding.
Steps on wiring multiple ohm speaker jacks guitar amp
|Disconnect your battery||This prevents the power flow||Guitar amplifier|
|Cut the wire originating from the speaker||This will help connect the guitar input to the speaker||Check the speaker wires from Amazon|
|Strip a quarter-inch wire||It will help when inserting wires||Guitar amplifier|
|Connect the wires to their respective ports||For a successful power flow||Check the speaker jacks from Amazon|
Step 1; Battery should be disconnected
Neither your guitar amplifier nor your speaker will receive power if this occurs.
If you want to know the amplifier I use, check the guitar amplifier from Amazon.
Step 2; Remove the speaker wire from the amplifier you will be working with
Discard any excess speaker wire that will be required to connect the amp input and the speaker output after you’ve made the necessary cuts. You should consider the route your cable will take to connect your amplifier to your speaker and vice versa.
Check the speaker wires from Amazon.
Step 3; a quarter-inch wire should be stripped
The wire ends will be placed into the terminals of the guitar amplifier and speaker wires, respectively, to complete the connection.
Step 4; connect the positive wires to the corresponding negative wires.
A wire marked with red should be connected to the positive input of the guitar amplifier and the speaker for this to function. To connect an amplifier and a speaker, connect the negative wire (labelled white) to both of their speaker jacks.

Understanding watts when wiring speaker jacks to guitar amps
If you need to save the speakers from a busted combination amp, the first thing you’ll need to do is figure out how much power each speaker is putting out. For me, it was two 80-watt speakers, for a total of 160 watts if I choose to run both simultaneously. After doing some research and snooping around on forums, I stumbled into this conversation.
The fundamental guideline is that the power output of the amplifier head, which is often measured in watts, should not be greater than the wattage rating of the speakers. Assuming that my amp is set at 200 watts and I am driving a 100-watt speaker, the speakers will most likely blow after cranking the volume up over 5 or 6. Amps consume more power when the volume is raised above 5.
For example, when your amplifier’s volume is set to 0, it consumes the smallest amount of power possible. When you raise the volume to 5, it consumes half the power, and when you raise it to 10, the amp consumes 100 per cent of its available power. The watts of an amplifier can also be used to calculate the final volume of an amplifier.
Therefore, smaller amplifiers with power ratings of 10, 20, or 30 watts are not only quieter, but they also inherently distort as their volume and power limits are reached, providing you with that charming, warm vintage tone that everyone is seeking. Your speaker is on the other end of the phone line. Think of a speaker’s wattage as the amount of power it can draw from an amplifier before it shocks you on stage or during practice sessions.
Wiring in parallel vs in series
When using several speakers with your amplifier, they are often wired in “parallel” or “series” configurations. If your guitar amp’s speakers are connected in “series,” this means that you can add up the ohms of every speaker to get the total ohm count for your guitar amp. Consider the following example: if I have two 8-ohm speakers connected in “series,” it implies my amplifiers have a total resistance of 16 ohms. In other words, you can run your amplifier at 16 ohms, and the speakers will not blow up since they are matched!
Alternatively, you can operate the amp at 8 or 4 ohms because, as previously stated, your speakers have a total resistance of 16 ohms and can withstand a lower load from the amplifier. Some speakers are connected in series, requiring a little extra calculation to determine the total ohm load. If the speakers are connected in series, you must reduce the ohm of one unit by the number of speakers in series with it.
Suppose I had two 8-ohm speakers connected in parallel. I would take 8 ohms and divide that amount by the number of units I have, again, two. This is how the math would appear in this case: 8 ohms divided by two speakers equals a total of 4 ohms.

Volume increases as the number of watts increases. Inspect your amplifier to ensure that the number of watts it produces does not exceed the number of watts the speakers can handle. If you’re only playing at home, you don’t need a 100-watt amplifier.
You should never, ever use an amplifier head larger in ohms than your speakers because this will nearly certainly cause your speakers to blow.
