Holy cow ... no one said anything about bridging 2 4ohm voice coils across 2 amp channels

further more I in no way eluded that there was anywhere near 800K ohms in ANY "speaker". I said that there was 800K ohms between the 2 channels of the amp GOING to the 2 voice coils of the speaker.

your a frickin rocket scientist man. I don't know how much plainer you need it explained to you to understand. A power source of any kind (including car amps) has no control of current flow what so ever. it's the componet or componets hooked up to the source that control the flow. the powere source (AMP in this case) just has to be able to supply the power at the rate the "load" (speaker in this case) will allow current to flow. If not ... things melt down, blow up, or smoke ... all of which are BAD mmm kay.

there IS +/- 800K ohms MEASURED between the channels of the AMP on the drivers side sail panel speaker JACK (with NO ) speaker hooked to the jack. This would be seen as an OPEN by the amp and my point WAS that the 2 channels ARE NOT bridged internally as some folks seem to believe.

resistance paralled is divided in half ... connected to a power source. If spread over 2 power sources is halfed again. This is where many novice car audio installers go awry when working with DVC subs as they'll get a 4 ohn DVC (or worse a 2 ohm) and parallel(bridge) the 2 coils. that hook it to a 2 channel amp bridged and end up with a 1 ohm(or .5 ohm if starting with the 2 ohm DVC's) and wonder why the amp goes into over heat or self protect, if they're lucky, after just a few minuets "if" they're not crankin on it.

The "lastly" portion of my thread you quoted was directed to richie77 ... and you for agreeing with him about this:

and had NOTHING to do with JL's in my car ... I think your getting lost in your own attempts to make someone look bad and are just reading what you want to hear instead of what's written and using common sense to put things together.

I don't have this much trouble explaining things to my 12 year old!

I've hooked up car stereo for many moons, have made more great sounding systems that I care to remember. I have fixed, tuned, re-routed and more efficently hooked up more systems that someone else screwed up or half-a$$ed at an actual car stereo shop that it makes me sick. When someone's spouting off things that are incorrect or incomplete espicially when others are looking to others for supposed good advice I'm gonna jump in and set things right.


I'm by no means the know all/end all stereo guru, but I have years of training and experiance in operating, fault isolation, and repair as well as practical, everyday working knowledge of electronics in general much less car stereo equipment.

 

Ummm..thanks for bringing me back into the equation.
Here's what I'm getting from this lively debate:
Each Voice Coil (VC) has 2 ohms of resistance? Camaros have a SVC, which makes it rated at 2 ohms. TAs have a DVC, so its rated at 4 ohms.

Am I right so far?

Ohms are just units of resistance, so a 2 ohm speaker will accept twice as much power than a 4 ohm speaker. The power that the amp sends to these speakers should be almost constant, right? The ohm rating of the speaker is what determines how much power the speaker accepts.

How am I doing?

So I don't think the amp will worker harder because there is less resistance. And since there is only 1 VC, the other channel (since I have a TA) won't even be used.

So back to my original question.... I'm thinking that I will be OK.

Please read my comments more in QUESTION form, than statement form...
I'm not trying to state any facts, this is just what I am deducing from everyones posts here, so far.
and BTW, thanks for all the input. :wink:

 

The T/A has a dvc sub, each coil being 4 ohms. Each coil is also being fed by its own channel from the amp.
What you're doing is running a 2 ohm speaker off of one channel of an amplifier that was originally running a 4 ohm speaker.
Aftermarket amps can handle a 2 ohm load on a single channel, not sure if the stock Monsoon amp can? Maybe it can though, as the Monsoon amp in the Camaro's do?

Does anyone know if the part number for the 2 amplifiers are the same in the T/A and the Camaro?

 

the voice coil resistance depends on the manufacturer or the speaker. In the TA both coils are 4ohm a piece so depending on how it's hooked up could be 1 load of 8, 4, 2, or 1ohm or simply 2 4ohm loads which is what I believe is the case with the TA monsoon amp.

ohms determin how much resistance to current flow the speaker has ... less ohms more flow... not so much how much power the speaker can take ... that depends on the make-up of the voice coil and strength of magnet ... etc

as far as you being "ok" running 1 of the channels @ 2ohms .. I can't honestly say as the actual manufacturer specs aren't available and Monsoon's web sites have been down/comming soon for quite some time now. I can't get in touch with them to get better spec's. "Most" amps now days rated @ 4 ohms can handel a 2 ohm load for some duration quite well and as long as not pounded on will never even go into over heat or self protect. if you crank it it might get warm/hot and shut down but I have no idea what kind of self protect circuitry is built into the amp... or not. they give the higher ohm rating to keep things cool and completely out of the danger zone as they don't want their amps blowing up any more than you do, it makes them look bad even if it was your fault. Monsoon's been arounf for a while and is known for making well made products but for the rating of the amp ... it's rather small 8 channels (some debate it 2 mids in the door 2 in the hatch area and 4 to the sail panel in the TA) coming out of one AMP and no one really knows (that I've talked to) the RMS rating of each channel, alot of guessing but I haven't found someone with a for sure yet. but even at say 35 RMS per 8 cannels in the aftermarket community would be a pretty substantial amp (2 amps for most manufactures)

I will be running mine bridged across a single 4 ohm voice coil initially and will give me 2 ohms per channel theroitically. and I'll see what happens there with the JL's worse case ... I have to put in an aftermarket amp to run them (oh twist my arm right ). I'll probably be heading that way soon anyway as I have a stealth box with a 10" kicker comp in route to the house soon

yes the amp works harder as it puts out more power at a lower load on that channel you have the 2 ohm load on versus a 4 ohm load. lower resistance will make it run hotter too.

I hope that clears it up a little

 

YES!!! thankyou ...

I'm not sure if they're the same I've got the p/n list for the TA's at work but I don't have the part #'s for camaro's at all

 

Well I wasnt trying to say anyone on here didnt know what they were talking about because I mentioned my training, I was just putting that out there for reference.

I get the 8,2 ohm loads from the 4ohm dvc but 4ohms would just be one voice coil hooked up *which is not recomended* and the 1ohm load im am just lost. Unless you are talking about running both dual voice coil speakers togeather?

Sick WS6
This part# 16257161 is for the monsoon amp out of a camaro.

 

if you briged the DVC's and briged across the 2 channels of the amp you would have 1 ohm

4/2=2 2/2=1 ...

if you ran said speakers in series then bridged across the amp you'd have 4 ohms

4+4=8 8/2=4

quite simple when you look at it

 

As stated before, just because the circuit reads 800k does not mean that it is an isolated channel.





Where did this come from?
This is totally random.
The resistance of the voice coils and how they are wired determine the electron resistance that the amp will "see". A lower resistance of the circuit will cause more electrons to flow through the transistor which in turn translates to heat. Heat is the #1 cause for electronic failure.







I agree. I stated this earlier.





No ones trying to make anyone look bad.
Nor am I hear to justify my knowledge with you.
I read a lot of threads on here and a lot of times I choose not to say anything... Unless someone is giving out bad information. You are proposing that people can use a 4ohm speaker and get the same output of a 2 ohm speaker which couldn’t be further from the truth. To top it off, you base this from a guess (a 800k ohms resistance reading of a output circuit)

 

never once did I say anything about a 2ohm speaker ... this whole thing has been about the 4ohm DVC in the TA ... (and the fact that he currently has a 2 ohm SVC camaro speaker there)

NO duh you won't get near the sound out of a 4ohm speaker ... I never said anything to the contrary ... I nfact I said a 2 ohm speaker will draw more current from the amp (and there for play louder)

AND I topped it off by going out to MY CAR and measuring ACROSS MY MONSOON amp and getting the ACTIVE ohm readings with no speakers hooked up to TRY and make some sence of what's going on "inside" the amp it's self as no one here really knows exactly whats' going on inside it for sure other than ... it puts out sound.There's no guess no maybe might be ... it IS +/- 800K ohms between the 2 channels, PERIOD, DOT! no question. WTF did you think I just pulled that out of thin air or something.

I've made my point and untill monsoons site comes back up I'm done with this post as there are several of you that choose only to read part of a post and try to make it sound like it's something it's not. Jimminy christmass have you ... never mind ... it's just not worth it ... Pewterpowre if you have any more questions PM me and when/if monsoon gets back up I'll get the "NO ****" answer form the horses mouth then all the fuss will be done!

Later!

 

Im glad we could both agree. You will not get the same amount of volume (measured in db) from a 4 ohm speaker as you will a 2 ohm speaker on the monsoon amp.

This thread is done. Pewterpowre, if you have any more questions, feel free to create another thread.
