Open Question

Powered subwoofer----sp-pwm55 Hello, I need the back part to the powered subwoofer(sp-pwm55. About three or four years ago it stopped working(after about 6 months of use). I took it apart and tried to fix it. I didn't accomplish that. So I storred it for about three years since I moved in with my girlfriend. Now I live by myself again and want to set it up(IT'S ALL LIKE BRAND NEW). But I must have thrown the powered subwoofer and the back of it away. I just ordered a new subwoofer but it didn't come with the back parts to it.(the connection part and power supply. Do you know where I can locate this item. system......TH-M55 powered subwoofer.................SP-PWM55 the serial # to the original subwoofer is.....178Y0886 Without the guts to my subwoofer it's all useless. And it's all like brand new. Thank you, Mark

SOURCE: JVC TH-M505 powers off right away

The unit is going in to shutdown. My guess is a failed output. Service is going to be required.

SOURCE: subwoofer not powering up

I could either be the sub or the main unit. The main unit actually sends a signal to the sub to turn it on so if that circuit is bad in the main unit the sub is never going to come on. I've also seen bad cables (You'd be amazed at how stubborn people can be when din connectors don't cooperate).

MOst of the time it is the jack that the cable plugs into that has the problem. .
Also the jack is not broken but HAS broken the solder connection TO the jack.
If you know someone who can safely take it apart and solder, let them try.

SOURCE: connecting an Ipod to JVC TH-M45 System

you can hook up ipod 2 different ways. the one i will use will be with a 3.5 to 3.5 mini plug connection(on both sides of cable it has i.e. head phone jack connection) and then set unit to aux in and that will give you sound from ipod. another way is with red and white audio cables to 3.5 mini plug connection. connect red and white to audio in on back of unit,and then set unit to that source.

How do I hook up the sub woofer to my home stereo system


You don't say what make or type either of the appliances are, so I can only answer in general terms.
First look at the back of your stereo system and see if there is a dedicated subwoofer output. If there is you should be able to find the correct lead between the two units by looking at both the connections. If the subwoofer is a powered one. IE with a mains plug on it, you have to plug it into the mains before it will work at all. The connection points also then need to be hooked up to the amp. If it's not a powered subwoofer then your main left and right channels speaker wires need to be split into using the subwoofer terminals provided. Another set of terminals on the sub, then lead to the main speakers.
Lastly if it has a dedicated subwoofer output, then the amp might have a setting that turns this on or off. So you might need to switch it on.

Does the subwoofer pre out if used, work in addition to the powered sub that is already a part of the system?


If the subwoofer you have already is not connected to that socket and is working, I would assume that is then a second socket for connection of another powered subwoofer.

You may have to connect the subwoofer output to a powered subwoofer.

My subwoofer seems to work for one song then stop. It is possibly over heating? I can I trouble shoot and fix myself. It is just 1 year old.


That's an easy one to find if it is overheating. Open up the unit and get it powered up. Get yourself a can of Servisol Freeze Spray. When it stops working spray a part which you think might cause it. Do this one part at a time, or you might get a faulty outcome. If the application of spray on a part brings it to life, you might have found the part. To be certain, heat it up with a soldering iron to make it switch off. Then try the spray again. If it does it twice then replace the part.

I have the sub woofer and two sp-thc5f front speakers. Can I hook this subwoofer directly to my JVC 56 high def big screen or do I need a dedicated amplifier that works this sub wooofer?


No, the powered subwoofer gets its signal AND power through the DIN connector so you'd have to second guess JVC engineers on which pins are power or signal; and what voltage level it supplies and then you'd have to come up with a source for the power. Managing the volume and relative levels would be a trick, too. Devastation lies down that path.

Get the prescribed JVC electronics or go with a whole new sound solution.

Powered subwoofer doesnt work .stopped a couple of months ago.it reads SW on the amp display.sw is turned on -green light on-wiring is all healthy and snug.home theater hasn't suffered any abuse.always...


I sounds like you have blown the woofer. open the unit and check. first disconnect the leads on the woffer, then use an ohm meeter. If you don't have an ohm meeter use a 9v battery across the speaker terminals. If you hear a thunk when the battery touches the terminals the speaker is okay. If tyou don't it's gone. If the ohm meeter reads some number like 4 to 9 the speaker would be okay. If it reads nothing or 000 then it's gone. If you need a speaker you can order it from Pro Line Music 215-736-8055

Want to attach a extra subwoofer


If you have a "subwoofer-out" jack on the back of the receiver, you can put a y-cord on it and connect it to two powered subwoofers. Don't expect a big difference in the sound, however. You may even get less bass depending on where you position the sub-woofers.

Hello, it,s very possible that it,s circuit protector built in to the sub (if it,s a self powered sub) gets to the point of overload and shuts off as a protection so that the speaker won,t get damaged and also so the internal amp tha,t pushing the speaker sound is also protected since theese amps all have heat buildup, their are two types of subwoofers ,They are the powered ones and the ones that are powered bt the surround amp ,The ones powered by the stereo surround amp/tuner tend to throw out less power to the sub and the ones that have internal power are mostly higher powered , Another thing you might want to check is your polarity to the speakers and also the omage , Most home theater system speakers are 8 ohm,s but their are speakers and amps that can be changed to 6 ohm,s ..so you might want to check the speaker rating also . Well hopefully you can use theese different methods to at least troubleshoot and discount the thing,s that are not the issues , Good luck and hope theese sugestions might help you , Sincerely Glenn
