Red light is on and subwoofers dont play but regular speakers play

Tell your source (receiver???) that it has a sub and set it up to feed LFE out of that RCA jack.

Prove your sub pre-out works. Or send something like FM on Tape Out to the sub and see how that works out.

How did you hook a speaker wire to this model of powered sub? What was on the other end of that speaker wire? It's not designed for speaker level input.

UNHOOK YOUR SPEAKER WIRES FROM AMP/IF THE GREEN LIGHT STAYS ON IT IS ONE OF
YOUR SPEAKERS.

There is no main AC power switch on the BU series; it's in standby mode whenever it's plugged in.

When playing music normal LED color should be green. After no signal for 10 minutes or so it will turn back to Red (Standby)

cd decks that can play mp3 format cds should be able to play regular cds. there is not mp3 mode per se.

There is a possibility that you may be overpowering or under-powering your speakers with the amp you are currently using or are playing notes below the specified range of "Hz" of the subwoofer causing the sub to sound distorted or as you would call it "chattering".
If the speakers range is 130hz-45hz and your playing notes at 30hz and dont have it tuned at the crossover either on the amp or the stereo to suit the subwoofer, the speaker will try and play the note regardless and will cause the cones to move beyond its range and may cause it to slap the magnet which can damage the subwoofer if consistently played that way. Please let me know if this solved your problem..

Yes it will work coming straight off the dirctv box. What kind of tv do u have that doesnt have an audio out. I have had to actually use rca splitters to get sound from bluray and cable box because the new samsung led tvs only have optical out. Dont forget the unit not being used must be off or u will have 2 source sounds at one time playing.

If you're looking for SPL (LOUD) go vented.
If you're looking for tonal accuracy (Sound Quality) go sealed.

The tradeoff between the two is that a ported enclosure will allow your subs to play highly powered. More air flow - better cooling of the voicecoils.

Sealed enclosures dont like much power because the coil cannot breathe and heats up rather quickly.

Its up to you, and your listening type.
Just remember LOUD = PORTED
QUALITY = SEALED

Bandpass is kind of a mixture of the two, however you give up some of the frequency range the sub plays at - and I dont ever recommend a bandpass enclosure to my customers unless they are looking to be flashy and light up the cones or magnet assemblies.

There are advantages and disadvantages to every enclosure type.
Pick the one that best suits your taste, and be sure to fire it toward the rear of the vehicle for the best response and cabin gain.

Thanks for using FixYa - a FixYa rating is appreciated!!

no not at all you enjoy sound ok...

I have the same speaker and it sounds like its behaving properly.

if you look on the back of the amp, you will find a switch that allows the speaker to automatically switch the speaker on or off based on the level of the audio coming from the tuner that it is attached to. If the switch is set to the auto mode, then it will listen for audio on the line and if the signal level coming into the subwoofer is high enough, the amplifier in the subwoofer will turn on and play. If the signal is not strong or loud enough, then the subwoofer will not turn on. There are two solutions to getting the speaker to work.

1. When you turn on the tuner or audio source that is feeding the Subwoofer speaker, you will need to turn it up loud enough to trigger the circuit in the subwoofer to switch on.

2. Alternatively, you can bypass the automatic circuit and set it to the "ON position all the time. In this position the subwoofer is always ready and waiting and should play any signal that is fed to it regardless of the loudness or volume of sound from the tuner. The switch is located on the back of the speaker cabinet just to the right of the red and black speaker wire connections. It is labeled "AUTO" and the switch positions are labeled ON and OFF.

Hope this helps!

If the speaker itself is working then the problem will most likely be the connection point where the speaker plugs into. If you dont know how to check for this problem, i dont really want to tell you just in case you hurt yourself. Take it to a shop and have it looked at by someone thats knows what there looking for.
