How do I wire my loudspeakers down to 4 ohms!?
My speakers are capable of a 4 ohm load and so is the amp. I need to know how to wire my 2 speakers (pair) so that I can get 4 ohms. Each tower has the normal -&+ terminal.
Oh, just so you know, the speakers are 8-4 ohms. Not JUST 4 ohms.
Yea. It say 8-4 ohms on the speaker. That means they are capable of 8,6, or 4.
just hook up with regular wire to the positive and negative and you’re all set. it’s good that your amp will do 4 ohms so that way even if you’re not getting the 4 ohms you desire it’s still ok for the amp if they’re working on 8 or 6 ohms. hope that helps dude.
This is all a little confusing. Your speakers are "8-4 ohms"? Normally they would be rated either 8 ohms or 4 ohms not "8 - 4". In reality the impedance varies with frequency. There will be peaks of capacitive reactance near resonance and inductive reactance starting somewhere above resonance. The actual impedance of an 8 ohm rated speaker will vary typically from about 5.5 ohms (it’s DC resistance) and 20 ~ 40 ohms. Put this and other speakers into a speaker system with a passive crossover and the total system impedance can vary more based on the crossover design.
For simplicity’s sake we’ll just assume an 8 ohm speaker is 8 ohms. If you have two of them and put them in parallel the net result is 4 ohms. If you put them in series the net result is 16 ohms.

Simply place them in parallel, plus to plus and minus to minus.
This will present a load of (about) 4 ohms to your Amplifier. I don’t
think you really need to be concerned with harmonics and resonance.
Most speakers are rated at 8 ohms. Don’t go less than 4 ohms, or you
run the risk of destroying your Amplifier.
