200x2 @ 4 ohms. 200 watts per side at 4 ohms.

300x2 @ 2 ohms. 300 watts per side at 2 ohms.

600x1 @ 4 ohms. 600 watts when the amp is bridged.

Sciontist, according to your explanation, the amp would put out 400x1 at 8 ohms, not 2. If you are going to simply add together each channels output, you must also double the load that the power was rated at.

If, you run it from 4 ohms on 1 channel, to 4 ohms bridged, the amp would be basically 2 ohm stereo added together.

 

thank you, the stereo man had come to put the infidels into their place.

 

eeeehhhh! wrong! haha... asking the amp to power one channel instead of two halves the resistance the amp sees. Doesn't matter How many voice coils the sub has.

If "bridging" the amp just combined the two channels to make more power and RAISED THE IMPEDENCE...what would be the point!! NO ONE EVER RUNS AMPS AT 8 ohms!!! the dropping of the load/resistance/ohm (going from 2 channels to one channel) is what raises the power. iF bridging increased the resistance..it would make LESS POWER!!


Larry Bird..You get to 4 ohms bridged if you have two 8 ohm subs (or dvc subs wired in series to 8 ohms)...then bridge the amp (aka. run a speaker wire from a positive terminal on one channel to BOTh positive terminals on each sub. then run another speaker wire from the negative on the other channel to the negative terminals on each sub) VOILA!!

the amp is bridged.. running at 4 ohms! making the most power possible

mandos...i THOUGHT you were some kind of stereo expert, but i've lost a lot of respect for you based on some of your recent posts. In fact, i've never even HEard of ED.. ImHO you got your tc, then went to ED and pitched an idea to be their link to scion owners...you know a way to unload some of their equipment..which you seem to have done a fairly good job of. I'm not questioning your salesmanship, just your technical know how... no offense though.

 

You really don't get it do you?? YOU ARE WRONG. I'm not trying to brag, but for credibility sake, I'm a first class certified installer, have been installing for years and I'm about to graduate as a certified electrician...I put together and take apart amplifiers all day long. Mandos is perfectly right...its is you that we should be questioning.

Your above statement is so wrong its not even laughable. You said that no one runs amps at 8 ohms, that shows how much you know right there....a sentence spoken by someone who obviously does not have much experience in the area. Especially since distortion levels are lower at higher impedances, it is much much cleaner to run an amp at a higher impedance such as 8 ohms vs. 4 ohms. DUH. There again, you're probably one of those who doesn't know what "clean" sounds like...you probably just like "loud" and truthfully can't tell the difference.

But getting back to your above statement...if an amp is rated at 200x2@4 ohms like you said above, then it would also be rated at 400x2@2 ohms...as everyone knows that most 2 channel amps are stable down to 2 ohms when run stereo (using both channels). If an amp is rated at 400x2@2ohms, then it would be rated at 800x1@4 ohms bridged...not 400x1@2 ohms bridged as you said above. Don't believe me?? Go pull up the specs on a common 2ch amp...

Yeah, you're the expert...that much is obvious. You ought to try listening instead of making stupid comments on how someone has lost their credibility with you (like your opinion is important to everyone on here). And nice job showing some immaturity by using this thread to try and tell Mandos what you think about his personal endeavors with ED. Who asked for your effin opinion? Mandos was dead on. And aside from our bickering...the original poster has a mono block amp. There is no such thing as bridging in his case, so all our arguing isnt helping the original question at all.

 

^^^ +1 Craig...

that's why I simply posted this and nothing else in reguard to this "noooob...OMG"(mocking the_sciontist)





and BTW: mandos could school 99.8% of the people on this board when it comes to anything audio related.....

 

You'll love that JL W1v2.4, it's a great speaker.. I have the 12" with about 250watts going to it and it sounds awesome. It's actually slightly louder then the older model w3 12" that I use to have.

 

HA!! The only thing you said that was rite, is that the OP is limited by his mono channel amp. YOU guys are obviously NOobs when it comes to wiring, amps and impedance... in the dozens of systems i have installed/wired/fixed, i've never met any two people as clueless as you two. have fun trying to figure out car stereo! ha ha ha ha ha ha ha haha...

 

Yes, of course.... all the go-to people on ScionLife are incoherent retarded _______s and you are the god of car audio, your ____ doesn't stink, you are a genius, you know EVERYTHING and you never make a mistake.....


now that I'm done spewing bull____ out my ears, I'm going to say this: Sciontist, I think you know the concept you're talking about, but perhaps should be more clear in what your thought process is.. (other than "gawd, youz ppl r newbs"...) maybe in reality we're all thinking the same thing but you're just saying it in a way that sounds incorrect..... ??? who knows, just a thought...

 

You ended being correct at that statement.

Yes, if you run an amp at 4 ohms bridged instead of 4 ohms stereo, it does halve the impedance to each channel.

But that makes it 2 ohms per channel, 4 ohm final load. It is NOT a 2 ohm final load no matter how hard you try to make it sound that way.

It sounds like you do have a basic understanding of how it works because of what I quoted above, you just seem confused as to how it ends up making power after that.

 

Finally, as for this statement, could you please be more wrong?

I've owned eD products much longer than my tC. I was set up for an interview at eD before and then totaled my Neon. Got a tC and came down. Ben was already a SL sponsor. Yes, I DID get him to stick around here, if it weren't for me eD wouldn't sponsor SL at all.

Also, how often do I go through peoples threads to tell them to buy eD stuff? Only if they request info about it will I post about it. It's consumers that have purchased products through us that suggest it.

 

No no, not ALL the people..just MOST. I'm no God...I'm the KING of car audio!

Yeah, i know my concepts, and have NEVER ever had a problem with car stereo, nor have any of my customers complained or had any problems with their systems.

I have a feeling we're all thinking along the same lines, just some of us are a bit confused..or are not properly explaining themselves.. OR are just spewing to much mumbo jumbo techno jargon that confuses EvERYONE and makes this whole thread useless. SOmetimes two people can read the same thing and see it differently.

But when you go from using TWO channels of an amp, to ONE channel... YOU're HALVING the load/resistance. NOT DOUBLING IT!! What would be the point of combining two channels if that amp sees a Greater REsistance??!!!! Lower resistance = more power. Bridging an amp= more power/wattage. Bridging an amp = lowered resistance (tradeoff is heat buildup and less stability at lower ohms..and more chance you're gonna fry something).

Period. the end. The king has spoken....."its good to be the king"

 

that's me!!

 

so you're trying to say that if you have a SVC 4ohm sub, and you hook it up to a 2channel amp (bridged mono), the amp will be "seeing" a 2ohm mono load???

if that's what you're trying to say, I'd have to disagree.... the amp would be powering mono @ 4ohm final impedance.... like Chris said, it'd be 2ohm per channel, but since the channels are combined(bridged) it's a 4ohm final load (because that's what the sub is)

If you have 2 2ohm SVC subs running 2ohm stereo on a 2channel amp, then want to run it mono, you could wire your subs to make a 1ohm final impedance or a 4ohm final impedance depending on series or parallel wiring....

on almost all 2channel amps, stereo 2ohm would = mono 4ohm in terms of power...

 

Wow..You are quite misinformed SCI TC GUY.. Maybe cuz you're only 20...hopefully in another 5 years you'll GET IT.

I really don't care if thats what you think..You OBVIOUSLY have NO idea what you are talking about. ha haha haha. thats fine..

If you have a SVC 4 ohm sub and a two channel amp, you could: a)use ONE channel to power the sub at 4 ohms at say 200 W. OR you bridge the amp (use a pos. from one channel and a neg. from the other) and have a 2 ohm load at 400 watts.. THOUGH THE SUB is still a 4 ohm load...YOU're SPLITTING the load between the two channels, halving the load the amp "sees". YOu don't NEED a DVC sub to wire in parallel or series off the AMP!

I'm Done.

 

HA! THis is ABSOLUTELY the most ridiculous thing i've ever heard!!! THis just makes NO SENSE!! Stereo means using 2 channels, mono means combining to one channel, Just so YOU know! You contradict yourself left and rite..and you don't even SEE IT!

 

He's not contridicting himself, you are agreeing with him and saying it completely wrong.

4 ohm bridged = 2 ohm per channel, same power, just in 1 channel instead of 2.

You are saying the exact same thing, and then disagreeing with people who say it in terms everyone else understands.

Please, for your own sake, stop making a fool of yourself.

 

that's exactly what I said.... a SVC 4ohm sub wired to a 2channel amp is 2ohm STEREO... which = 4ohm MONO....

yes the amp will "see" a 2ohm load from that one channel... and a 2ohm load from the other channel.... but since it's ONE SVC 4ohm sub, the FINAL impedance is 4ohm MONO.... everyone knows that if you take a 4ohm sub on one channel, and wire it to both channels, you'll get more power because you're using both channels.... but you WILL NOT GET A 2 OHM MONO LOAD!!!!!! you'll have a 2ohm STEREO load that is actually technically a 4ohm mono load because the amp is bridged to ONE sub......

a 400x1@4ohm (that "x1" means mono/bridged/2into1) amp will give you 200x2 @ 2ohm..... the 200x2@2ohm is the reason you can get a 400x1@4ohm... when you hook up a SVC 4ohm sub to 2 channels (bridge the amp) you're giving half the resistance of the whole sub to either channel... meaning 2ohm STEREO at the amp... but since it's not technically a stereo setup, it's MONO... and since you can't change the impedance of a sub, it's 4 ohm MONO (bridged)

 

Since the original posters question was answered long ago...and this is just going to go back and forth....locked.
