How to connect 4 speakers to a 2 channel amplifier

[nickloss]

geez...I've got a bunch of those terminal blocks lying around... Had never considered using them When wiring audio systems before. Pretty smart. keeps everything nice and neat too!

I ask you the impedance of amplifier and ohms needed?
How about the connection?
What' you call that wire connection?

Ok, but you’re assuming the amplifier is rated to perform at the new impedance created when you put another speaker in parallel.

So, if (per channel) you have an 8ohm speaker connected and you add another 8ohm speaker in parallel to the same channel the impedance that the amplifier will now see is 4ohms, not 8.

An amplifier will output up to double the watts when you halve the impedance, this means there is always a minimum impedance rating the amp can function at. Otherwise you could continue adding speakers making your system louder and louder.

Your amplifier is now working twice as hard effectively.

Interestingly a doubling of output will only add +2 Db. This is significant with a small system but becomes strange when you get into massive PA systems where a 40k system will only give you 2DB more than a 20k system.

So if your amp is rated to work between 8ohms and 16ohms then you can it 2 speakers er channel in parallel and that would mean the amp is seeing 8 ohms which is fine.

However, if you put 2 8ohm speakers in parallel, then your amp is going down to 4 ohms, and is working far harder than it was designed to do.

This will result in a dead amp.

Be very careful when connecting additional speaker to an amp. Ohms law, If one connects a very low impedence to an amplifier that is not rated for low impedance loads. This can quickly burn up the amp . By the time one smells smoke, the damage to the amp is done. Impedence/resistance is extremely important when pairing to an amplifier. Low impedance means less resistance and possibly an excessive amount of current which causes excess heat in the amps components.

Will running 4 speakers and 2 subwoofers on a 4 channel amp sound better than 2 speakers and 1 sub, thr bose accoustimass 5 series 3

[lazydayswax]

can you please explain to me, i have 4 speakers connected to my amplifier each have there own spot, now i want to add a subwoofer how do i connect it to it

[silversandman]

What happens when you directly connect both wires of the 2 speakers directly into to banana plug of the amp ?

Bro I have 4 4ohm speaker I bought 7$ amp from china should I do this??

[jazznjayy]

where do i get one of those connectors

[HaharuRecords]

Why don't just join the same colored wires on each side instead of using that joining thing right there!

Can i get your email i want to show pic of my amp and speaker

[atgamer]

Sir i have sony speakers original speaker is 120w and i have 2 ch Amplifer sony original but i want some more sound then i buy 2 more speaker of sony which is 100w each original speaker impedance is 6ohm and which i but is also 6 ohm my amplifier is 2600w and output is 120w+120w can i connect these 2 100w speaker with your idea???? Is it alright because i dont want to damage Amplifer

so you start your video pointing out the - and the + which is obviuos because we can see Then when you show the wiring we cant even see where the wires come from - or + crikey shite!!!!
