Front two speakers not working at all

*Remove drivers side centre console panel
*You'll see a black plug on the "side" of the stereo, this is your speaker outputs and constant 12v+.

Dark Green - / Light Green + = Front Right Speaker
Grey - / Brown + = Front Left Speaker
Light Blue - / Dark Blue + = Rear Right Speaker
Yellow/Red - / Brown + = Rear Right Speaker

Are we looking at this same computers? Since when do you require drivers for speakers?!? Speakers are dumb devices (yes, this is correct name for passive computer devices) and do not require any drivers in any computer or operating system with sound capability! Computer speakers are compatible with any copmuter in the world and any operating system which generate sound!

These speakers are qualified as 5.1, that meant that these speakers will have front bass, front centre speaker, front left and right speaker and rear left and right speaker, in total six speakers.

Please follow this advice and you will have joy of surround sound.

1. Mount your subwoofer in front centre, below your knee level at the distance of about 2 of your hights
2. Mount your centre speaker in the centre on your head/hight level or slightly above at same distance as subwoofer or slightly closer.
3. Mount left front speaker about 45degree from your centre line to the left and right same distance to your right, on the level of your head while you are listening to the music, distance from you slightly closer (about 1/2 your hight) than your centre speaker.
4. Mount your rear left and right speakers at same or slightly greater distance as front left and right speaker. these should be at same or slightly higher level as front speakers.
5. Triple 3.5mm jack is going to your computer output and your speakers (incidently, your subwoofer servers as junction box, amplifier and mixer).
6. Connect speakers to they respective jacks.
7. Turn power on speakers all way down
8. Connect power to the speakers and switch it on
9. Play some music on your computer, output on full, music recommended will be some classic, like bach or similar
10. Put your hand in front of subwoofer and turn bass till you feel vibration
11. Turn sound till you hear it well
12. Turn sound on the computer down till about 70% - 80%
13. Turn on sound on your speakers till desired level and enjoy the experience!

If you have still some problems, these can be then related to the drivers installed on your computer, please check therefore what motherboard do you have, if there is proper sound drivers installed. If not, go to the site of our motherboard/sound card manufacturer and install relevant drivers.

Please do not hesitate to ask me if you have any addtional problem related to this particular issue.

These are "decent" quality 5.1 speakers, new were on about $100.00 to $150.00, have two years warranty from time of purchase.

Now, to your question, you will not have 5.1 "surround sound" effect with standard sound card, standard sound card will provide only three speakers sound, rear speakers will not connect.

Connect speakers as follows:
1. Audio from PC, orange, green and black connecting to front right speaker.
2. DB15 (D-SUB) connecting to subwoofer, subwoofer is serving as mixer, power board, amplifier and connection box
3. White plug is connecting to front left speaker
4. Red is connecting to front centre speaker
5. Black is connecting right rear speaker
6. Yellow is connecting left rar speaker.

Establish location of the speakers, from experience in ideal world:

1. Sub should be on about your knee level or below,
2. Front centre speaker should be about twice your hight distance from you, on front and slightly above your head.
3. Front left and right speakers should be at about 45degree from your axis, at distance of about 1.5 your hight and on the level of your head or slightly below.
4. Rear left and right speakers should be located similiary to front speakers, on they level or slightly above them, again, about 45degree from your axis.

Location of the speakers is more actually important than it is assumed, total sound immersion is not possible without proper speakers installation. Head in these instruction meant a location of your head while you are listening to your music or recording not whil eyou are standing.

In reality... hang them higher than your head in four corners of your room, front centre higher than sides, woofer lower than sides and below front centre, if they interfere with each other - increase the distance. I hate reality...

After speakers are connected:
1. Plug power cord in,
2. Turn all sounds totally down, including subwoofer
3. Increase sound on PC to maximum, let play any known to you music, tufftuff or bach, whatever, do not bother with metallica as you cannot discredit on it correct levels.
4. Increase subwoofer volume, holding one hand on the front of the grill till you get some vibration from it
5. Increase sound on centre button of the right fron speaker till you achieve equality of the sound
6. Decrease sound volume on your PC to about 60% - 70%
7. Increse subwoofer volume till you feel sound on your hand in front of the speaker.
8. Increase sound volume on front/rear speakers as required.

Hope that short intro solved all your speaker problems, enjoy! if you require any additional help, do not hesitate to answer to this post with request.

connect any speaker instead of center speaker if you get the same result you will have a problem in amp itself if the problem fixed change center speaker with a new one

try to replace a new audio cable

it may just be the way the card was programed

ah yes you are so right, thank you.

my left speaker isn't working. I've check the connections. what can I do? 

just check is there any loose contact frm that speaker connection plug out the cable connect it again and have a check it may work...

or may be any time the speaker may be falled on ground so may be there is problem

take amp to a workbench, have a test speaker in hand, touch the speaker wires to each channel to see if all channels work. take each speaker to the amp and temporarily hook one at a time to see if any speaker is bad. if you eliminate the hardware, you know it's the wires in between.
