The Truth About Ohms...
#54
Just so you know, posting something that somebody else says doesn't make them facts.
this is hilarious. dude your a dumbass just go eat chloride tablets
what i find hilarious is that if my words are so wrong, then why, OH WHY! can no one prove this wrong... i just get called names. it doesn't take a genius to understand what im saying.
surly someone can post an intelligent answer otherwise... im all for an intelligent argument on the matter..

dude you been trolling for hours and thats all you have.. name calling. funny. choke on the fumes your amp puts out at 1 ohm.. you, of all people i figured you would be able to see through the BS and back me up.

For whatever reason you think that like when you double the resistance you're also doubling the efficiency.
sure you gain "a" db here and there by going with the lower ohm and more watt method. Great for someone who has a spl meter in their car getting measured during a competition.
but on a day to day basis.. why would you torture your amp for a inaudible gain of a db or two?

your right. and thank you for finally giving me a reason for your remarks.. your right you don't, but you do gain some efficiency from the sub. fact right? a low resistance on your amp causes it to be less efficient. Fact right? (produces more heat and audible distortion) which is wasted energy.

if u know what ur doing with ur amp then u can run it at whatever u want.
yay for that guy. he can run at .37 ohms. wow he must have won all types of awards with that system. awards for the worst sounding, loudest system.
trent on what terms would you close this thread?

then look at how much it makes at 8 ohms.
It ill be a TON more, more than a db here and theres worth of power. I run the lowest possible impedance possible because it gives me the most power, and my amp is rated for it.
which is less work! less magnetic flux. less output. at double the watts..

there is a difference between having a loud every day sub system and a competition system.. competition systems are made for Burps and short amount of usage.. Maximum dbs. would you want that for your daily driver? no you just want a loud *** system.
any of those db competitors run their system for hours at a time? if they do I would give them mad props for being able to run that loud of a system for extended periods of time.

RangOH, your explanation of the electromagnet with more or less coils makes perfect sense to me. I see exactly what you're getting at and it's true as far as I know. However, if I have a 2 ohm stable amp, and it's louder at 2 ohms than at 4, and still sounds good, you're damn right I'm gonna run it at 2 ohms. I don't really care if it's 'torturing' my amp.. if it's two ohm stable then it should be fine, if it fries, then I get another one.
I think it's a matter of sound quality.. I am an SQ guy personally, so if my sub sounded crappy or if I could tell that it's clipping, I would switch it up to a higher resistance. But I really doubt that I would be able to tell the difference. By the way I'm running my amp at 4 ohms, simply because I only have a single 4 ohm sub with a single voicecoil. I'd like to pick up a new dual voicecoil though and run it at 2 ohms. At 4 ohms I can pound bass for an hour and my amp will only be slightly warm to the touch, for what that's worth. I wish I could set it up for 2 so I could see the difference, in SQ, SPL, and heat.
Anyway, my 2 cents, all this is great information, the immaturity in this thread is unfortunate, because otherwise it is very educational. Unfortunately I now feel stupider after reading the last couple pages. Thanks for posting that though RangOH. It's something to think about!

That makes zero sense to me as well. If your amp is clipping and you make the resistance higher you're going to have to turn your gain up, which equals even worse clipping if it was doing it to begin with. The smart thing to do would be to turn your gain down some and leave everything else alone...

Nate thanks for that... it did get out of hand.
Its a new day.
higher resistance will make the amp less likely to clip...even if you do have to turn the gains up high. the transistors will have to put out much less current at 8 ohms. your running them at low levels. there really shouldn't be any clip because your running them at half the output. on a 2 ohm load you would clip the signal at much lower gain because they are running full tilt already with no resistance to keep them in check.
One major draw back at low ohms is a loss of dynamic range. theres no longer soft tones and loud tones, its just loud tones and loud tones.. dynamics is gained when you have a powerful amp that is run at low output... the amp will move the sub effortlessly at the quieter tones, and slam the loud ones. its called having "headroom" your amp should always be more powerful then the speaker its driving. this whole gains thing would not even be in the equation if your equipment is selected right.
Great! its always good to have first hand knowledge of what your doing. I wish more people would try this approach. instead of rangerboy's

Im running my sub and amp at 2 ohms right now. I switched it yesterday for $*!ts and gigs to 4 ohms and it sounded really effin crappy it was clipping big time. maybe its just me.
Im not one to like over powering bass. I will admit i do like bass, but i like it clean and i like to hear the words and instruments in the song. I tried your higher ohm theory and i dont know if maybe i wasent adjusting the amp right but no matter where i turned any ***** it clipped horrible. Maybe ill mess with it again today, yesterday i ran out of time.
ive always ran mine on 2 ohm with this sub and amp combo and I have Never had my amp over heat or anything... Never smelled it cooking and i have cranked this baby sky high, for songs with tons of bass

I think that you may have inadvertently wired your sub down to 1 ohm yesterday. i think that you've had your sub running at 4 ohms this whole time.. with dual 2 ohm you only have a choice of 1 ohm or 4.

thats the amp im running
Car Audio Amplifiers - JackHammer JH300 | MTX Audio
The way I have it wired I checked with the manual and its a 2ohm or 4ohm deal and I have it wire the 2ohm way
Thats the sub im running its the single 4ohm
