difference between 2 and 4 ohm speakers/subs?

subs i'm debating over

 

Thats easy math......4 - 2=2ohms (is the difference)

most amps give a higher wattage output at 2ohms.

 

First, I wouldn't get those subs.

Second, Ohms is the measure of resistance. The higher the resistance the less the amp can send to the sub and vice versa.

 

thanks for the replies guys.

what's wrong with the subs?

they also have a 12" on sale.

 

I'm just not a fan of 15's. Those are pretty darn cheap, but I've never listened to them before.

 

Hey Now - they are MB Quarts - how could you go wrong?

 

No, they're NOT MB Quarts. MB Quarts were designed and built in Germany.

These were spec'd by Rockford and built by one of Rockford's China subvendors.

The difference is that amps put out more power into 2 ohms, but many aren't stable with 2 2 ohm VCs (whcih in parallel measure 1 ohm, which will shut off or blow up many amps).

The real question is, what amp will you use? That should dictate what VC values you get - and how you wire them after.

 

DING DONG ! Was waiting for "The Man" to chime in. Good info like always. Make a different sub selection. Price is good but not worth it.

 

Hey Bro, so dose this mean that you can turn speakers that are 1-2-3--4-(or)8 ohm ratings into different ohms by wiring teh speakers in parallel or bridged?

 

Only to a point. 2 and 2 can be 1 or 4. 4 and 4 can be 2 or 8. 8 and 8 can be 4 or 16.

5 is right out. (Monty Python and the Holy Grail.)

 

So its all in how you wire it basically?

 

No, no all.

2 and 2 can't be 2. 4 and 4 can't be 4.

A lot of people with two dual voice coil woofs think that if the just think hard enough they can make a combo that is impossible, that's why I'm being specific about it.

 

Just remember that with audio signals, "ohms" refers to impedance, not resistance.

Impedance is basically the resistance within a certain frequency range of an alternating current (which is what an audio signal is, essentially).

Remember the speaker is a load. You cannot push more current to a load at the same voltage. The load needs to draw more current. A lower impedance allows more current to pass, and more current means more power, if the amp is designed to handle it of course.

 

can you have a 2 ohm speaker on a channel with 3 other 4 ohm speakers, or do they need to be the same? My 06 TSX stock amp isn't liking the new infinity 2ohm speaker i put in - is that because its 2 ohms and the others are 4 so its resetting itself?

 

First off thread revival and no!! All the speakers need to be the same impedance(ohms) and they need to be wired down to the correct impedance to match what the amp is stable at. And those infinity 2ohm speakers arent working right with your factory amp because its prolly set up for 4 ohm speakers.

 

Revived it cause no one likes new threads about something that has already been discussed! (nor do they respond to them)

So angry at crutchfield - they insisted this wasn't the issue when i suggested it, shouldnt even buy the replacements from them at this rate. Now going for some Boston Accoustics models. Will see how they do - i really dont want to keep tearing my doors apart. also got some dynamat extreme to go behind them... http://www.crutchfield.com/S-fcC33bs...stics-S55.html

We'll see.

 

Crutchfield has good enough customer service that if you're unhappy with the speakers you bought, you should be able to return them to crutchfield for a trade in. I think their time limit is 30 days for the return though...

 

Hey, a quick way to see if your factory amp is happier with 4ohm or 2ohm with out useing special tools,just your ears and if system cuts out.Take your 2ohm speakers,first wire one,turn it up,listen to it.Then take both and try wiring them in series this will give you a 4ohm load,again listen.one or the other will sound beter and not cut off.

 

i'm just going to return the 2 ohm speakers and replace with 4 ohm speakers.
thanks for all the help, you guys are great!

 

i got one of the boston s55's in there. seems like a lot less bass coming from the door now, however highs and mids are clear as a bell. Can't find a ton of reviews. I used dynamat around the enclosure to reduce vibration and noise distortion.

they are only 35 watts RMS 100 watts max - what are the stock pioneers? anyone know? (i have a 1G TSX)

I really want to make sure this is not a downgrade

 

Do you like the sound of the speakers? If so, then why worry if it is a downgrade?
