1. Speaker ohms varies with the frequency youre playing through them. 2. Measure the ohms from the end of that long speaker wire Jamaicans use, and you will find you're closer to the 8 ohms, and well well pass it too..
Mighty action yes its corey aka mr platinumprovocateur thank you for clarifying my two questions really appreciate it. So yes my double 18" bass reflex, B&C 8ohms drivers so as i said to my mate we should not play it in the option he said by doing 3 and 3 on each channel. though I did say to him we should do it 1 on each channel and use another amp 1 on each channel and we shall be safe because we use parallel wiring. thanks again king
Nice video bro! Big Up. However from my little amplifier circuits theory, the output signal from the amplifier depends on the input signal which is controlled by the knobs (attenuators) in front of the amplifier. The higher the input signal into the amplifier the higher the amplified signal out of the amplifier. The quality of the input signal (in terms of distortion and noise) and the amplitude level can result in an amplification of the same causing blowing of speakers due to overheating. Therefore I want to concur with @aaronlake although a very high-wattage amplifier can blow a low-wattage speaker even with a low signal level at the input.

am glad I asked the question so am satisfied yes big man this was just very informative you have gone above and beyond Mighty Action bless you from corey aka platinumprovocateur over here in the United Kingdom
My favourite is building banks of series and parallel. The limit always comes down to size, storage and transport. Hence people end up using the most compact and most powerful equipment. If you have a decent amp you can go super low. As soon as the voice coils warm up the impedance is much higher. I run 24x 1" drivers and i have had 26x in parallel across 4 channels. That amp was ok with it but it was not even designed to go to 2 ohms. Now they are on a 4chan 2ohm friendly. This is 1.3ohm per channel but it's only 1" drivers that warm up quickly and average much higher than 1.3 ohms. If your amp is overpowered and your load is small the impedance can be quite low, if the amp is quality.
no no no check the battery of the meter. the resistance wont be correct if your meter battery is low.the first reading immediately you attach the meter terminals is 7.5.so kindly replace the meter battery you will get the correct figure .thanks
Bridge mode just changes the 2 channel amp to a Mono block amp,both sides are being used to power a single output. As action said if you you run it hard 24/7 it will break.
Very informative. I've done a lot of research and found out these things too. First mi eva really hear a sound man come out and talk bout these things. Keep up the good work. 2 a side with some with some 21's can help build up back the loudness instead of 18's.
Big boss I was in Milan when your video drop I've come back to 🇬🇧 👀 you 📹 there's some things I've learnt that I never knew I was doing wrong before 🙏🏿 up big boss 🇱🇨🇲🇸🇬🇧
So about the ad442 and ohms,, you said the subs are not 8ohms so you would NOT recommend 4per channel and that is a good advice BUT, remember "WIRE RESISTANCE " as you (previously mentioned and tested) most speakers wires are between 50ft-100ft which will automatically bring the ohms from 6.2ohms to 8ohms. Connect a 100feet speaker cable to the speaker and test the ohms from the other end of the cable and Please inbox me with the results
I have a question how can you test to see which is positive and which is negative on a amplifier if it rubs off or if it's not indicae thank you for the good work. Thank you so much. Very helpful.
Although manufacturers label their speakers @ 4, 8, and 16 ohm as just a standard, this is why they refer to it as "nominal impedance" But the actual DC resistance is usually lower. There are many factors why this is so, but it is not something you should be overly concerned about because a speaker's load is not static. It changes do to the coil moving and it changes at different frequencies while under load... I suggest you look up impedance rise, more commonly referred to as "Box rise".
the AD442 can do all six double 18's, each channelwill play 3 woofers at 2.6 ohms. wiring NL4 1+ 1- equal channel 1, 2+ 2- equal channel 2 (same way for channel 3 and 4) this way you will have 2 4 conductor speaker leads. first nl4 to 1st double 18, nl4 jumper from box 1 to box 2 then to box 3. Do this for channel 3/4 also. DO NOT BRIDGE AMP
Dont know if its factual, but what i was thought is that with wires considered the amp should see the missing 1.5 ohm. The wires for a 100 ft 12 ga. should drop between 1 to 2 ohms.
Mighty action, speakers are not resistive loads they are reactive loads, meaning while playing music the ohms load changes with each frequency (impedance rise) more often than not your amplifier would not be seeing let's say 2 ohm if your speakers are wired to 2 ohms, because of impedance rise the amplifier would be playing at a comfortable level. You should do some research on box/impedance rise.
Go easy my brother! Let’s clear up something. While it’s not necessarily 8 ohms using your white board 6.2 x 4 speakers is going to be 1.5 which rounded up equals 2 ohms! While it may be shocking to see those 8 ohms speakers actually reading less you have to realize they are other factors at work so in actuality the output of the amplifier isn’t going to be constant when it comes to VOLUME which is what we really work with so while we focus on ohms and watts with speakers what’s really important is the SPL! 👍🏿👌🏿so keep in mind that these numbers that you see with these specs are based on a reference using (2,4 or 8) ohm load. Under test conditions you would have a constant output with constant loads hence the reason for those numbers aka(reference) As you were sir. Don’t knock the 4 a side my friend continue there’s much more to learn 👏👏👌🏿👌🏿👍🏿👍🏿
arite me general so is it possible that when a technician build or recoil a speaker would u advise to let the technician drop the ohms to around 6. 2ohms cause normally i see technician rewind it at 7.6 or 7.9 ohms .. whats ur thought on that?
Bro it seems like you are relaying information that's been told to you so I'm not going to hold you to it. The reason you are getting 6.2 or 6.3 ohms is because you are reading the dc resistance when the speaker is connected to the amplifier then the coil puts out a higher value because its now in a AC circuit. In the sound system business tweeters and horns are coupled in series which gives you a better chance of not blowing them in a 4 or 5 way system each section has it's own amplifier so playing highs and horn at 16 ohms and the others at 2,4 or 8 ohms doesn't matter. And you add resistance in series not multiple cause if you had a 4 ohm in series with a 8 ohm multiplying wouldn't work as to how you doing it . Also a little nugget when you put two speakers in series it can only play as loud as one where each speaker will only play to half its potential but will survive more often than parallel.
If your input signal into the amplifier is too high it will cause it try turning down the signal before it goes into the amp and then turn up the amplifier.
