Windows 10: Car sub-woofer + home system speakers to computer - help!

Thanks for explanation, did good for non electronics engineer. I am pretty good when comes to Home Theater setups, minus the PC. From what i see and think about thread starters use with this stereo just might not sound right or work right as far as i can tell. Now if you can help him get it right, Good luck ! Guess rather get usage out of it, rather then buying speakers for PC this i can understand.

 

I can definitely get the sub-woofer to work, but it's recognized as a middle speaker, not a sub-woofer in the Realtek HD Sound Manager software, so it won't work as a sub-woofer just yet. Any work-around to this issue?
Thank you jds63, and you're definitely right!
Edit; I don't have the option to swap center/ sub-woofer in the Realtek HD Audio Manager, which would most likely solve my problem. Fill speaker and Enable Bass Management is also not there.

 

Your welcome, all i felt was how can your sound card send the proper low tones through the left/right stereo channels when clearly it has a separate connection on sound card for Subwoofer which is not being used in this case.Also Amp does not have a connection proper for sub.My assumption of this scenario.

 

Do you think I could only power the speakers instead of the sub-woofer instead?

 

Yes, that should work o.k..Some sound card and this is integrated change coded color for each speaker. From what i see from your pic Grey is side speakers, black is rear, yellow looks like sub and green should be front, others are mic and line in.

My integrated which i do not use, using PCI card, orange is my Sub out, as it looks yellow in pic you posted, only color difference i noticed for standard color coded. Yours is 7.1 channel integrated, as it has side channels.

See what other member has to say about it for you first.

 

For just stereo, use the green jack.

I suppose that it might be possible to use the subwoofer connection and a separate mono amp to drive the sub. (I've never done that. The 2.1 systems that I have use only the green jack, and have their own crossovers.) You'd have to figure out which of the two channels from the orange jack is for the sub.

You might get into some weirdness because the two small speakers would also receive the low frequency stuff, but as long as you get the phasing right, it may be OK. (If the phasing is wrong, the signals will subtract rather than add, and you'll lose a lot of the bass.)

 

Dude, do you have some death wish or something?
There are far easier ways to set a house on fire than playing with electricity!

You got:
- a piece of trash stereo/mono-bridged amp
- two pieces of trash 6ohm speakers
- one piece of trash unknown ohm subwoofer

You want:
"2.1"
Not gonna happen.

It's either 2.0 or 0.1:
- use just the piece of trash 6ohm speakers in stereo mode (2.0): cables remain as in the 4th picture, NO FREAKING WOOFER CONNECTION ON TOP, UNLESS A FIRE IS WHAT YOU'RE AFTER

- use just the piece of trash unknown ohm subwoofer normally if it's less than 8ohm (0.1) and use something else for speakers: stereo jack goes from yellow PC output to L mono amp input, subwoofer cables goes to one of the red+black pair amp outputs

- use just the piece of trash unknown ohm subwoofer in mono mode if it's 8ohm (0.1) and use something else for speakers: stereo jack goes from yellow PC output to L mono amp input, subwoofer cables goes to the 2 middle, red amp outputs, NO CABLES ALLOWED ON THE BLACK OUTPUTS, UNLESS A FIRE IS WHAT YOU'RE AFTER

SOME OTHER WAYS TO START A FIRE OR AT LEAST BREAK EITHER THE AMP, THE PC, THE SPEAKERS, THE WOOFER, OR ALL OF THEM THAT YOU MUST DEFINITELY TRY. OR NOT:
- speaker one (+) connected to speaker two (-) then the other ends connected to one of the black+red pair amp outputs, then the woofer connected to the other pair amp outputs. I would love to hear that 12ohm "speaker" + sub!
- speakers connected as stereo, woofer connected on top of one of the black+red pair amp outputs. I would love to hear that 3ohm "something" + 6ohm speaker!

This might sound harsh, but I assure you it's not. People instead of having fun at some club, lost their lives because some moron decided to "pimp" sound outputs and the whole thing end up in fire.

EDIT: this is not something to be politically-correct with. AMPs can kill people. Or at least destroy property.

 

Thank you for the warnings AveYo!
So I've connected the sub-woofer as you told me to, I've tried both the first and second method. The sub-woofer still works as a center speaker, not a sub-woofer in the Realtek HD Audio Manager software. There is still no option to change the center/ sub-woofer speaker output. That option is apparently normally there, no clue why it's not on my software although I guess it has something to do with my motherboard.

If there's no work-around I'll definitely give up on it and use my piece of trash speakers in a stereo setup instead!

Edit; If I use the red cable instead (right) of the white one (left) as you told me to, and turn the volume up high enough you can hear the test tune go through the sub-woofer as intended, it's just really low. In other words It's recognized as a sub-woofer in the Realtek HD Audio Manager software, as long as I use the red cable to right amp input instead of white cable to left amp input.
Edit2; If I turn off the bridged mode on the back of the amp the volume suddenly gets louder? Not sure if this is how it's supposed to react, or if it's still acting like a center speaker.

 

That's why I've used red for the unknown ohm subwoofer part. It makes quite a difference if it's 8ohm or if it's below that as bridged mono mode requires 8ohm or higher, on any amp I've seen. From the pictures posted I can see it's mentioned just under the red outputs. I don't see a bridge turn switch, but if there is one, it should have some warnings as to what you can connect in bridged mode. Most likely the subwoofer is below 8ohm (4?) so it's unsupported, cannot gain x2 output power. Stop connecting it to the two red outputs, instead use a normal black+red pair.

Anyway, there is no good choice when it comes to pairing 3 speakers to a single amp. Most, if not all 2.1 commercial products are actually 2 ams in one.

Best bet is to use the current amp for the 6ohm speakers in stereo mode, and get another cheap mono amp for the subwoofer.

About realtek gui:
- some options appear only under 7.1 or 5.1 mode.
- enable bass management and full-range options.
- disable auto popup dialog under Connector Settings, then use connector retasking option when right-clicking output panel icons

 

Thank you again! I think I got all information I need or more, so I'll mark the thread as solved.
