Hey guys I'm in need of some help, I know a decent amount about audio equipment. I have an elongated 8' polk audio subwoofer - model number UL 1492 or LR106476. I moved my surround sound to my dorm room. I was hooking it up and I had the red and white audio cable plugged in and when I sat it down the cable did not reach and therefore broke the tips of into the audio receptors. I removed the tip from the red jack sucessfully, but cant remove the white one. I was wondering what part should I buy to replace it or what I could do. I would be greatful for some info soon!

    I don't know if you can see that clearly, but the red input is clear, and the white or negative is clogged with the tip.

    I would try a pin, needle or a small nail to remove that.

    I've tried that, actually both broke off and i cut one end off a cue tip, put super glue on the end and pulled it out, but its not working for this one. What is the name for the audio receptors? I'm guessing I will have to buy new receptors for it, could someone give me a link to where they sell these?

    I could be wrong but I believe you only need 1 unless it's some kind of sub/sat setup that requires R/L. I only use one on my SVS.

    yeah I've plugged it in with one, but it only has half the power with one, it doesn't seem near as loud.

    It seems lower in volume due to half the input voltage, but that shouldn't affect the output wattage of the amplifier. Make the needed gain adjustments to compensate. If you are getting the signal from a receiver that has adjustable subwoofer gain, move it up by 3 dB.

    Ok I have two tuners, one that controls power output (Hz, from 60-180), and volume (60-180). I noticed it has 2 inputs for speakerwire, and 2 outputs for speakerwire, so I went ahead and plugged the inputs with my reciever, it seemed that it may of helped some, but not much. Do you think it makes any difference hooking them up? Also is there anyway I could just buy a new svc box?

    One knob is the crossover frequency cutoff, the other is volume. If you are handy, you could unplug the unit from the wall and take out the screws that mount it to the back of the box. This would allow you to see if the broken part could be removed from the inside at all. The whole amplifier is mounted to the metal plate that you see and should be easy to get into.

    I took apart the sub, and took two photos of the amp.

    I believe the vca receptors are by the yellow glue or muck. How much would a new amp cost?

    You can replace the RCA connectors if you know how to solder, or a local TV repair shop can do this for you. Shouldn't cost much, my roommate in college had this done for $20 IIRC.

    If it were me on a budget I would go get a roll of speaker wire and use the speaker level inputs....
    Too much **** to list....

    awesome thanks, I called around yesterday to some audio places, and they were going to charge me 25$ just to look at the sub, even when I told them what is exactly wrong with it....I'm goin to try some tv repair shops now.

    i'm looking to purchase one of these used, but i can't find the user manual anywhere online. does anyone know what the ohm resistance is and how many watts are in these bad boys? i'm hoping it's compatible with my onkyo tx-nr535.
