I want to add two more speakers to my room using my current stereo, is there a way to? It may be a little out dated but it gets the job done, heres what the back looks like.
So is there a way to?

Depending on the impedance of the speakers, and what impedance loads the amp can handle, you could try a couple scenarios.
You could daisy chain the speakers in series or parallel, once you answer the 2 vital questions above, the solution will present itself. Judging from the 'plastic' back of your amp/rec, I'm willing to bet series is *probably* going to be your only choice.
Is that a mini system?

Well since I'm new with speakers and stuff, I don't know what impedance means, sorry. The only thing on the back of the stereo that I would guess has anything to do with the amp is this: 240V 220V 120V. It says those 3 numbers in a row.Depending on the impedance of the speakers, and what impedance loads the amp can handle, you could try a couple scenarios.
Again, sorry for my misunderstandings, but I don't know what a "daisy chain" is.You could daisy chain the speakers in series or parallel, once you answer the 2 vital questions above, the solution will present itself.

Yeah, from like 1990Is that a mini system?

Anyone? Bueller? Am I on my own here?
Fine.
What mini-system is it, brand and model? What speakers are connected to it now (brand and model), and what speakers do you plan to add (brand and model)?

If you want more loudness, then get more efficient speakers (but don't expect it to sound spectacular on mini system amps)......if you want more bass, then get a powered subwoofer. If you want more loudness *and* you want it to sound better, then sell it, give it away, use it in another room, however you chose to get it out of the way and just get a real system
-
Jess, I read you loud and clear, should have taken that stand initially.
Can't wait to see how *this* one progresses.

Well obviously, he wants something more. But hooking up two different speakers, two different fr's two different impedance curves, all for the sake of loudness is kindof "ghetto", there are better options.
-
most mini systems are pretty "ghetto" to begin with
-
All well and good, but also for the sake of experimenting, and trying to make the best out of a BAD situation is o-k in my book.
At the minimum, he can get his learn on.
Two different FR's? Why would that matter, in ANY given situation?
Impedance curve, irrelevant. All speakers (individual drivers or as a whole) show *some* sort of curve at given freq's. Nominal (avg) impedance is what we are concerned with in this situation.

Let's throw in some Eminem.......you have some KLH Rave's and some R15's, both running full range.......take a wild guess what happens next.
If one speaker is flat and the other is midrange happy, then there's going to be shelved off trebble.
Same with bass, the two speakers probably have different rolloffs, resulting in what would probably be anemic deep bass and overemphasized mid-upper bass.
Of course I'm assuming he wants more loudness, and will place the two pairs of speakers on top of eachother, or at least close to eachother. If the extra set is going, say, on the other side of the room then have fun. It's not optimal, but I'll simply leave it at "whatever".
Impedance, ok.....I was talking out of my ****. Nevermind. -
Man, I'm not feelin' ya on this one. (assuming the 2nd pair of speakers to be added is somewhat similar to the original...ie not SRS's and JVC $20 plastic cab jobs)
So what if different speakers exhibit different 'tonal' qualities. Why if speaker A is flat, and speaker B is midrange 'happy', how would that affect the overall upper octaves? It is what it is, no?
Maybe I'm not following you, but I read your post like the speakers will affect each other, ie, the whole is NOT stronger than the individual.
Perhaps one speaker can make up for (at least partially) the inadequacies of the other, vis-a-vis. Perhaps it could make it worse?
How would placing speakers near (or far) from each other make the overall sound inherently louder? I can see him effin with the placement to change the soundstage, funky or not....but louder?
If he is forced to increase said resistance of his speakers (by running in series) does that not increase the resistance load (impedance) on the amp? Granted, the efficiency of the speakers can come into play here, but it should not play quite as loud (at any given unclipped power), as running *one* pair alone.
Are we actually discussing this? Something to be said about 'root' or 'back to basics' discussions.

Well Russ, I honestly don't know what I'm thinking right now. Just seems like it couldn't make the most perfect blend, like a mismatched center or something like that.If he is forced to increase said resistance of his speakers (by running in series) does that not increase the resistance load (impedance) on the amp? Granted, the efficiency of the speakers can come into play here, but it should not play quite as loud (at any given unclipped power), as running *one* pair alone.
Yes, if they were run in series then I can't see how it would be able to go any louder. If it were run in parallell it would probably blow up the typical mini system amp......I say leave well enough alone, get a sub, or more efficient speakers, depending on what he wants, and if that doesnt do the trick then screw the mess. -
Well I told you it was outdated.. it's some Magnavox POS, nothing great. I just don't feel like shelling out the money for a new one while this one works perfectly. Heres some pictures of the main part, then the speaker which i have another one running from the other corner. I'm looking to get surround sound, so I want two more filling the remaining corners. Ehh and yeah I know my wires are just exposed like that.

SURROUND SOUND!?!?!?!?!
Well why didn't you say so.............
http://home.earthlink.net/~kantack/surround2.htm
Just hooking up two more speakers isn't "surround sound", its just two more speakers .....the link above shows circuits that can extract "ambient" information (reverberations and such that should come from behind the listener) and reproduce them using a myriad of different speaker configurations. I reccomend the first one, it's simpler and pretty much guaranteed to work, unless your amp has *no* balls *at all*. -
On the link you sent, on the picture it has "volume control". I already have volume control on my current stereo, do I need another or something?? Heh being new at this stuff sucks.
-
No.......the volume control on the component (the big black box with all the knobs and such) simply controls the amplitude (volume) of the signal going to the amplifier.......the amplifier then powers the speakers.
The "volume control" in the digram is really just a variable potentiometer, operating on the signal after it's allready been amplified. In simplistic terms, it lets some of the signal through to power the rear speakers, and throws some of it away, hence reducing the volume of the rears. Turning it all the way up will let the rear speakers play as loud as they can in relation to the mains, and turning it down will make them a bit quieter.
You may prefer to have them turned all the way up at first, but eventually you might get sick of the novelty effect, and want to turn them down.
It is, however, perfectly possible to build that circuit with no volume control. It will work, but if you like the sound or not is a different issue.
Also, make sure to turn off your system before you start to rewire and make sure its wired *exactly* as shown in the diagram, you don't want to create any shorts.
Also note, if you don't have expensive wire, you can pull the two wires apart to make the single wires needed to wire the rears. (Although its not shown as such for readability, the wires going to the mains can be together, no need to pull them apart)
BTW, just exactly what speakers are you going to hook up as rears?
Also, I'll assume we're talking about the first circuit? That would be the best one to try if you have 2 pairs of speakers and have no idea what you're doing, hehe -
BTW, if you do decide to connect more speakers, make sure the unit doesnt get too hot, the sound isnt compressed and strained, and oh yeah....if you see smoke, tahts bad
Just be careful, since most amps in mini systems don't have too much "chest hair" -
While it won't be true "surround sound" you can do it and be surrounded by sound.
Scavange the local thrift stores and find as many pairs of speakers you need to add for a total of 4 pairs. I recently spent $20 and picked up a couple pair. Score yourself some wire. At this level I suggest 16awg lamp cord. It sounds decent and can be bought by the foot pretty cheap. Some lengths of this you'll have to tear down the middle to separate, but it shouldn't be too hard.
You can use 2 pair on each side of your TV, 1 pair above or below your TV (or one above and one below), and 1 pair in the back of your room (probably facing away from you angled into the ceiling and corners if they are close to where you sit).
Connect the 1st speaker like you normally would (+to+ and -to-), connect the 2nd speaker to the first +to+ and -to-, the 3rd one would have the + to the +, but don't connect the - (this comes later and this is where you may need to tear the lengths apart), connect the - to the + of the 4th. Now connect the - of the 4th to the - of the 2nd. This shouldn't change load on your equipment and it SHOULD be alright. If I had a scanner or could use some sort of drawing program I would.
Of course you'll have to experiment with placement. If your TV starts changing colors move the speakers that are closest a little further away until it goes back to normal. I'd use the speakers with the biggest woofers up front.

Ah man.......I'm not even touching this one anymore. Kinda hard to stand up for yourself when you're wrong. Usually I might try to defend myself, but today I degress, I will simply say "WTF" and move on. -
BTW.......I really don't want anybody to feel bad, it was my fault anyway for being a smartass.

Hmmm...
so if I buy...some passive SVS and hook them up in the same terminals (along with the JVC subs) and run them off that same terminal on a JVC shelf system it would be good? lol, could only imagine the smoke and flames...
then add some Wilson Audio X-1 in the main terminals along with the JVC mains...man i can just imagine that...- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

Hmm I dunno, depends how much I can get some decent speakers for, I don't want to put too much into it, less then $50. I already have enough speaker wire, so I'm okay on that. So once I'm able to goto a thrift store and see what they have. Thrift stores at the ish -

I can draw it but it's hard to explain. And I probably explained it wrong anyways. In summary four 8 ohm speakers hooked together in a series and parallel combination will result in an 8 ohm load. This can also be done with 9, 16, 25, etc. speakers.Make it Funky! -
i think i get it, because the parrallel circuit drops the load and then the series ups the load? correct? two 8 ohms in a series is a 16 ohm load and 2 8 ohm speakers in a parallel circuit is a 4 ohm load, so they kinda cancell eachother out? is that how it works?
