4Ω vs 2Ω vs 1Ω etc.....


Recommended Posts

So as the title suggests... Is one amount of resistance more disireable than another for any reason? This is assuming that the power remains constant regardless of the resistance.

So given that power is constant, is there a difference between the resistance of a given subwoofer / wiring configuration? I seem to remeber hearing somewhere that higher resistance is better because it pushes more voltage instead of higher amperage through the speaker, and is easier on the voice coil because of it. Can someone confirm / deny this?

In subs it doesn't matter, you select whatever voicecoil config you need to get XX amount of power from amplifier.

uhhh. The coil config that you want to run is entirely up to you. I mean if your amp is 1 ohm stable then most people would want there final load to be 1 ohm (giving them the most power)....so...depending on how many woofers you are running will depend on what coil you want.

Great calc to play around with. now it doesnt show you everything but its probably more than enough for you at this point.

beer sucks...but i can bring some jose cuervo. Only problem is that it makes me horny and gives me the rams. So unless yall wanna fight and then have some great make up sex i will leave it home.

Whats bull?

Yeah, I would like to know too. It's a legit question. Oh, and I found where I read about it...

"Different amp designs with different purposes..High voltage amps have a much higher cost due the parts used in them...high current amps are much cheaper however they are MUCH harder on voice coils due to wiring them down below a half ohm to get the power out of them..." - NDMstang65, audioforum.com

He is talking about regulated vs unregulated amps. And current does produce heat, but for the most part unregulated amps that are wired down that low are usually for SPL meaning you only play a note for 10-15 sec even 30 sec max and then done. That short amount of time it isn't going to matter that much, or matter to the point of saying one is better then the other.

just helps you on the amp end of the set up

1 ohm rating is usually higher than the 4 ohm rating on the amp

gives you more power, more wiring options when you wire it all together

lower ohm load gets you more power. higher ohm load gets you less THD. but no one cares about THD here.

If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

I'm new to the world of car audio... What is THD? And how can a lower ohm load give more power than a higher ohm load? I know that it is harder for an amp to push the same amount of current through a higher ohm load... But if two different amps are designed to give the same amount of rms power, albeit at different levels of resistance, are the both still different?

Ohms law homie

Voltage = Current X resistance

That is LAW and is always true. So if resistance goes down, current has to go up to keep the same voltage. How regulated amps work is they regulate the voltage to match the resistance so you get the same power at 1 ohm or 8 ohms. You see?
