All right so i turned my speakers on today and noticed the back and centre channels where not working as they should. The centre/sub is extremely low volume and if i stick the jack in half way, it sort of works for a few seconds and then nothing. Its definitely the connections on the sub not the speakers; problem is i cant get to see the connections as there is a plastic surround over them. The speakers i got on sale for £40 a couple years ago and ive used them daily so its not a major loss but id rather not have to spend money on new ones. As you can see, the connections are all soldered on and glued so it would be a wee job to get them off just to find out one of them might be fucked anyway.
