You need to check the signal. If there is not signal present or the volume is low the sub will not turn on and goes in to sleep mode.

I have a Th-C50 home theater and lost my subwoofer system cord, can I use a regular s-cord to make that connection? or is it useless with out the cord?? Please help!


Hi,

Yes you can use any 2-core cable to carry the bass signal to the subwoofer. As the bass speaker cone is the largest cone in your speaker set I would recommend a good quality cable of decent gauge (thickness) to carry the bass signal.

You just need to make sure you have the right connectors for the amp and sub and make sure you connect positive to positive and negative to negative.

Hope this helps,

Chris

Subwoofer not working.... JVC surround sound system 778V Subwoofer Part Number SP-PW37-SUB I hear a hum coming from unit so there's power going to it. I hear weak bass thumps with volume turned all the way...


A connectivity check could provide the solution, notice any wrong wire connections on device or any other devices requiring interconnection. The woofer would perform properly when the connections that provide current for woofing are approapiate

important notes
1. Trace the connection from Recorder or sound output to the woofer device
2. The wiring connections should be sound and video ouput into sound and video output into woofer.
3. The connections if any problems would be located at the stereo recorder or device producing the spund and video. Check the connections of wires on the recorder device ensuring rewiriing
4. finally, adjust the equalisers if any the buttoms could have been disbled by master switch hindering full blaster boost sound.

Set your equalizer to you a V shape or U shape pattern, bass effect can only attain by adding a powered subwoofer, (amplifier and subwoofer). subwoofer without an amplifier doesn't sound good, your system doesn't have enough power to drive your subwoofer.

"pop" in speaker when turned up


more likely your deck is just running out of power. another cause is the speaker leads could be hitting the metal of the car with the bass, check for clearance.

My subwoofer fuse keeps blowing out , what might the problem be ?


There may be a loose wire inside that is moving from the bass and shorting out when it touches the wrong place inside. Check and see if that's what it is.

If not, try turning the Bass/Volume down some on the Subwoofer so it's not putting so much of a strain on the Amplifier.

Another thing you could try, but it's usually NOT recommended, is to use a fuse with a higher Amperage rating so it's a bit harder to blow.

I hope this helps :)

Best Regards,

James

My JVC RX6000VBK does not get the signal from or to my subwoofer.


i had the same problem a few times, they are pretty picky receivers.
first take a look in your settings and make sure none of your speakers are set on large, if they are they automatically shut off the woofer,
2, try the adjust option and crank the bass and throw on the bass boost
3. manually turn the woofer on through the receiver itself
4. try and turn up the woofer itself if is powered
5. try hooking the woofer up to the secondary speaker jacks by bridging it, (positive on left and negative on right for even power)

if none of these options work then the woofer itself may be defective even though it lights up

Sounds like your original and this sub have bad amps. The amp for the sub is not the same as the amp for the other speakers. The old unit has a dead amp and this new one is on the way out. (Pulling too much current on high bass)

Systems shuts off if sound gets too loud.


Yes, i had this same problem. If it was too loud, at level 37+, any loud boom would shut down the subwoofer, subsequently shutting down the speakers. As such, I figured it might have been the 8 pin dim cable, but that wasn't it. What solved the problem was lowerin the BASS level. Not the level on the subwoofer, but the actual BASS level. I had it at +10 (the max) and it was too much for the system to handle. I don't think I ever had it like that so I'm assuming someone, maybe my daughters, moved the settings. But anyway, moving the bass level back down to either 0 or +3 at most maintains the "boom" effect of the subwoofer minus the shutting off of the system.
