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.

Subwoofer rattle


Try filling the inside of the enclosure with insulation [roof insulation will work ] or a small pillow just to see if its the box or the driver rattling if its the driver you might have to secure it to the enclosure with screws or something ,

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
