How To Wire A 2 Channel Amp To 4 Speakers

4 channel amps that handle 2 ohms bridged are less common but they are out there.

How to wire a 2 channel amp to 4 speakers. Hopefully you can see all the possibilities this creates. Run it so your left speakers are on one channel with the rights on the other. Lorenzo shows you how to wire your speakers to your factory wiring harness being powered by the head units amplifier or an aftermarket kenwood amplifier. Amplifiers are available with 2 4 5 and even 6 channels so you can use these principles.

Now as you can see the amp will produce 60w per channel at 8 ohms and 120w at 4 ohm. Obviously a pair of speakers would get 50w each speaker 2 pairs will get 40w each speaker. Using a speaker selector switch is the simplest and safest way to connect four or more speakers with a 2 channel amplifier. On a 2 channel amp there are four terminals.

Justin just for clarification this isnt bridging. A common setup with a 4 channel amplifier is to wire 2 speakers each in parallel to channels 1 and 2 for a total of 4 then bridging channels 3 and 4 for the subwoofer. This is the first and best choice for most modern 4 channel amps. 2 speakers in parallel to each front channel 2 ohms x 2 1 subwoofer wired for 4 or 2 ohms on the rear channels bridged for more power.

So say the amp is 50x2 at 4 80x2 at 2. Right channel a positive b negative left channel c positive. Wiring speakers in series raises the impedance delivered to the amplifier while wiring them in parallel lowers it. How to wire four speakers to a 2 channel amp.

Amplifiers have both a minimum and a maximum level of impedance and it is important to stay within these limits. Now from my days of car audio amps subs etc i remember that with a 2 channel amp you could run 4 speakers from it with no problem provided the amp can run at the appropriate resistance. To bridge a two channel amplifier locate the amp terminals. A positive and a negative for the right channel and likewise for the left channel.

Each terminal will be labeled as follows. To connect your speakers using this method all you need to do is to connect the input wires of the selector box to the output jack of the amp and then connect all the speakers you have. Which one to choose depends on both the speakers and the amplifier specifically their impedance levels and limits. How to bridge a two channel amp.

Yes two 4 ohm speakers in parallel will net a 2 ohm load.
