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

What is supposed to go in there? Could that be why my sound isn't working?

It is a proprietary controller that plugs in to that port. Kind of a wired remote, that controls on/off, subwoofer volume, and speaker volume.

I have a Denon AVR-2801 that I have owned for many years with almost no problems. I have 5 speakers and a subwoofer connected to it - the speakers are connected through the wire inputs on the back and the...


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)

I turn on my subwoofer and the volume is turned down and it makes a loud buzzing sound, and its not even hooked up to the amp, just pluged in. Thank you, Joel Arntsen


You might have blown the speaker. This happens when you play things too loudly and you ruin the speaker inside. You can test this by playing something with a decent amount of bass and turned up a bit. If you hear like a "rattle" in the sound or like something isn't right in the heavy bass notes, then you definitely blew the speaker out. This isn't a tragedy. They're fixable if you bring them to a place that repairs speakers. But I would definitely test it first by hooking it up and playing a loud song with a lot of bass. Hope that helps a little! Please rate my solution!

Speaker connection out no sound


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

I put an after market cd player in my 2003 acura 3.2 tl type s. all the speakers are working fine but i am not getting any sound out of the factory subwoofer, it is not working. any idead what i did wrong...


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

8 wires on my 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?
