Speaker Installation

[bigTee]

Rait, i need help with wires and speakers!

I'm going to get a 2 channel amp, but want 8 speakers to run off it.

Its for a shop.

Speakers will be 8omhs and amp says 8-16omhs.

I'm looking at series and parallel installation, but it's confusing me.

In idiot terms - how do i do this?

Hi Big Tee.

So for each channel you have 4 speakers. If you make your total o/p 8 ohms for each channel instead of 16 (you state that your amp will drive 8-16 ohms)then your o/p volume for each channel will be louder than if you have a 16 ohm network.
For each channel, connect 2 speakers in parallel ie + to + and - to -, that will in effect give you a 4 ohm speaker.Do this again, then you have 2 x 4 ohm speakers.
Connect these 2 sets of speakers in series ie - of one set to + of other set. You then have a network of 4 speakers. Connect - of first speaker to - of amp, and + of last speaker to + of amp.
Repeat for other channel.
Hope this is step by step enough
Regards

That won't work. Gimme a minute and I'll do a picture!

There you go. The issue with what you posted was 1- You were shorting the outputs together. 2- You had no functional circuit because of this. In effect, you' only connected the positives together.

To clarify, I've done it slightly differently. 2 8ohm speakers in series to give 16ohm pairs. The pairs are then in parallel to give 8 ohms overall.

Rumbly said 2 8 ohm speakers in parallel to give 4ohm pairs, then 4 ohm pairs in series to give 8 ohms.

Either way, they are functionally identical!

Just picked the picture up on my phone, as abbotsmike stated, his or my way will work the same.

OP unless you already have the kit, then look at using a 100v line system, far better and more flexible for what you want, probably cheaper kit as well. If you want more info then just ask.
