What Is the Blue Input Port on the Back of the AOpen Subwoofer?

Pliug both soundbar and subwoofer in, Press and hold the "input" button on the soundbar for 4 seconds. The display should show two asterisks flashing. Press and hold the "pairing" button on the back of the subwoofer. The subwoofer light should turn blue (from red).

Hi, you do not have many options, check source fuse and take authorized service

Hola, no tienes muchas opciones, revisar fusible de fuente y llevar a service autorizado

Maybe start with speaker test tones to verify the hardware instead of messing with live audio modes.

BTW: the powered subwoofer is supposed to be driven by the 'Subwoofer' Pre-Out.

What input are you using that allows audio when you select EXT IN AND the other modes? That is a specialized analog input for 5.1 analog equipment ONLY. (Page 32)

Hello
Who is Mexico? Who are you talking to? We are Fixya dot com, a site full of Experts who help people. There is no one here called 'Mexico'.

Monitors don't have audio sound out unless that have an audio input from your unstated PC. The audio out is on the rear of your PC. The socket is normally Green and looks like the one in the attached image.

GREEN - "line out" --> speakers with their own amplifier to boost the sound-level

BLUE - "line in" --> connect to "L/R audio output" from a cassette player

RED - "microphone input" --> microphone

You got to connect the blue amp turn on wire. If still dont work. then you got to find the factory amp find the two wires that sends frequency signals to the amp. You will see a total of 7 wires. So you've got to use process of elimination. Use a multimeter.

1.Constant 12 Volt
2. Ground
3. Amp turn on
4. + output wires going to the + of the subwoofer
5. - output wires going to the - of the subwoofer
6 + input wires going to the radio harness
7 + input wires going to the radio harness

6 & 7 are like the rca's you plug in at the input of an aftermarket amplifier and and on the other end plug in the output subwoofer of the Radio.

So on a factory amp you wont see any RCA's its all wires. Once you find the first 5 just remember the last 2 wires.

If you want your radio to control the gain and volume of the Subwoofer get a long RCA plug it on the back of your radio that says sub output and then cut the other end of that RCA and connect the positive the + input wire on the amp and the negative to the negative input wire on the amp.

If you dont know whats positive or negative just go ahead and connect it and experiment. You will know if your in phase when the subs sound boomy. Then the connections are correct. If it sounds Tinney then the connection is out of phase. solder then tape all connections with black electrical tape. Dont leave any power wires exposed or else cause a short and blow fuses.

Good luck

i think it is a shortage with your cord connecting to you subwoofer

"One has positive and negative input, another positive and negative output (red and black on each)"

Just from your description, it sounds like pos/neg input are the 12 volt pos neg supply for the amp inside the subwoofer. Red is pos, black is neg.

"positive and negative output (red and black on each)"

This sounds like it's used if you want to proved 12 volt pos/neg to another component.

"and a third wire with left input right input positive and negative (blue, red, yellow and black)"

This is for the cables coming from the "subwoofer out" on the amp. This is 4 wires altogether -- correct?

check for the power button is on behind the woofer or speaker,if ur speakers does not have switch hten select the volume control optin and click the properties and check the sounds by clicking the speaker images in that window.if u have problem again,askme through fixya again.

sometimes adapters do not work.
this might work
start computer without mouse. you may have to work with keyboard tab key as you press tab key you should see the icons highlighted install drivers plug in mouse to usb if lucky O/S will recognize mouse and setup
