How do i wire 4 speakers to a 2 channel amp?

Answer 1

You need to run them in series or parallel. It depends on what speakers you have and what ohms they are. Check out this site, it explains what to do. Hope it helps.

Answer 2

you can do that by putting 2 speakers in parallel on each channel of the amp output BUT you had better beware: The "impedance" of the speakers may be too low to do that without damaging the amplifier.
To put 2 speakers in parallel on a channel of the amp, simply wire the red (hot) wire and Ground (Black) wires to both speakers from the amp.

One of the main properties of electronics is Resistance. In Alternating-current systems The resistance is called "impedance". Resistance and impedance are measured in units of Ohms. Volts is the force required to overcome the resistance and Amps is the amount of electrical current travelling thru the system. When the speakers are put in this "parallel" configuration, as far as the amp is concerned they become one speaker with half the impedance - so it will cause the amp to have to output 2X more current for any given amount of voltage - and that can make the amp burn up.
Common speaker impedances are 4, 8 or 16 ohms.
Many amps can drive a "load" of 4 or 8 ohms with a certain amount of current - so if you remove an 8-ohm speaker and replace it with 2 8-ohm speakers in parallel, the demand for current goes up and if your amp isn't rated to drive 4 ohms then you'll be in for trouble.

Another configuration for wiring the 2 speakers would be to put them in series, but you don't want to do that - if one speaker gets disconnected you lose all sound from the channel.

Series resistances add up so 2 8-ohm speakers in series results in a 16-ohm load. 2 of the same speakers in parallel results in 4 ohms.
The Current (amps)multiplied by the Voltage (Volts) equals WATTS which is total power and also a measure of heat. If you drive 4 speakers at a lower Load impedance the demand for current goes up and the result is that the WATTS your amp must supply goes up and then your amp gets too hot and will smoke.

See what the minimum "load" your amp can handle before choosing your speakers.
Also, speakers waste some of the energy sent to them and that's a measure called Efficiency - if the speaker has a certain amount of power required to be very loud, then you will want to choose speakers that have a power requirement close to what your amp can put out. if the power requirement is too high the amp will not be able to make the speakers very loud. if it's too low then the amp will blow up the speakers easily.

Answer 3

Depends on the connectors, i guess. But as long as you connect the R & L wires into the right place, you can double up i.e. put two wires from each speaker to the input.

Answer 4

In parallel
