Sub woofers are just mono amps. They feed both the right and left output together. So all you need is a stereo to mono cable. The two jacks go in the sub and the single mono into one of the terminals on your amp. The other terminal will allow another sub to be connected I think, though please check your manual for this.

SOURCE: Wharfdale moviestar 70 speekers and sub

i have the same moviestars 70+ plus a yamaha rx-v750 put the crossover on the sub to maximum (left knob) volume (right knob) about 2/3 clockwise. change the crossover on the yamaha to anywhere from 80-120 ( the 120 will put more bass to the sub) if your yamaha has sub level/volume control set it higher, also if it has LFE/sub out set it to sub only.
Good luck!

One possibility is that the mute switches on your speakers have oxydized contacts INSIDE the switch - this kind of malfunction mostly occurs when the equipment is exposed to moisture and/or smog.

The most common solution is to change both switches, but they can also be disassembled and cleaned up (which is a bit more complicated and time consuming).

Another possibility is a dried up filter capacitor in the power supply or somewhere in the preamplifier section, possibly also a bad preamplifier chip but if your speakers work fine (with the exception of the mute switch noise), then the problem is more likely with the switches.

Also, check the internal connectors for any dirt, broken wires or desoldered pins.

Could also be something else, you should know i'm only assuming on the possibilities and i'm listing the most common problems i've encountered so far.

Which model sub woofer can replace JVC SP-PW100?


The simplest thing would be a like-for-like replacement. Ebay or Craigslist would be good sources if the sub is out of production. There's one listed on Ebay UK for 39 sterilng. Item number 171423774447 - ends 16th Sept 2014

For new replacements the answer depends partly on how you connect and then partly on where you live. I'll deal with connections first...

The JVC has both high-level -speaker cable sockets- and low-level -phono/RCA- connections. Budget subs with both sets are getting rarer in the UK.

If you are connecting from an AV receiver with the low-level phono cable then the Tannoy SFX sub would do quite nicely. It's 99 sterilng at Richersounds.

For a sub with high and low level connections then the Wharfedale Diamond sub is about the cheapest in wide distribution. 170 sterilng at Tesco, 150 sterilng as an open box special at Superfi. Personally though, if I were considering spending 150+ on a sub I'd go the extra mile and plump for the BK Gemini at 215 sterilng direct from the manufacturer. You're getting 300+ sterilng performance because they cut out the middleman.

If you live in the US then there's a bit more choice. Have a look at Bestbuy. The Pioneer SW 8mk2 isn't bad at 159 dollars. There's the Theater Solutions SUB6F at 88 dollars if you just want cheap. Respected speakers brand Polk has the PSW 108 at 199 dollars

I have bought JAMO sub 250 subwoofer and Pioneer VSX919AH-K amp. Please advise how can I connect them. The amp has one RCA out for sub but the sub has two line in sockets (left and right). Do I need to use...


Hi,
You don't need such cable, although you can use it if you have one. If receiver has only mono SUB output (as majority of receivers have), you just connect it to the Left socket on the Sub and it will work.

Using the Y cable would probably cause that you will fed the same signal to both left and right sockets, but half the intensity (you would divide the output from receiver by 2). So in the end the Sub would receive exactly the same signal as when using normal straight cable.

No sub signal from a CDX GT520.


connect the speake(sub) directly to the stereo(just use one of the rear 6x9 speaker wire to test the sub and make sure it's not the amp. if it does not work, it's the sub

Need wiring diagram for Sony XM-E70 Equalizer/Amp


You need 1 thick ground cable ( usually brown)
you need 1 thick power cable ( same thickness and wire as ground usually red )
you should have 1 rem wire ( thin blue )
RCAs, 2 for sub, extra 2 for 2 speakers.
The rest I have no idea what they are.

You need speaker cables to sub or amp.

Some products use different colouring. Maybe the 9 pin connector is for head deck to speakers.

Alpine type-r 2ohm dual voice coil help


try reconnecting your rca's from the deck to the amp when finished wire one speaker positive to positive on left channel and negative to negative on right channel then connect the 1st subwoofer. if all power and sound is fine and working turn off power to amp and connect negative terminal of 1st sub to positive on 2nd sub and positive from first sub to negative on second crossing the wires runs the speakers in series another way to try is parralel the speakers wiring by connecting positive left channel output of amp to positive on 1st sub same with the negative then splice positive to positive on second sub and same with negative.
