Hi, I've got a Sony CMT-GP5 which I've just bought an Accusound powered subwoofer for. Unfortunately the sub is producing very, very quiet sounds - Even with the Sony and Sub turned to full volume, the sound is very low. The sub/cables all work, as I've tested it on a surround sound system. It seems as thought the output from the sub jack just isn't giving enough umpf. Any help with this issue would be very much appreciated. Thanks for your time!
From the description the subwoofer is the problem, since the item is new return it to the place of purchase, this is a manufacture issue.

It sounds to me like you both are having a problem with a capacitor going bad. some capacitors act as a noise filter and it sounds like you both have a bad one. If you are any good with a volt-ohm meter that reads capacitors you should check them to make sure they are at their proper values which will be posted on the capacitor. then replace it. if you dont know how to use a v-o meter then take it to a shop and have them replace it

Check your speakers maybe one are about to burn out

Check your connection settings.... plug all your connections in a proper manner as given in the manual...

Secondly sounds like the power supply filter capacitor has gone bad. Write down the value off the label and purchase one at your local electronics parts place. It will only be two solder leads to unsolder and solder back. But first check the other place for that symptom, an open ground near the input jack going into the amplifier, or broken input wire/plug.

You need to connect the speaker output from your desktop to the PC IN jack which is Front Panel Bottom Left. Full details are on Page 2 of the above Manual "Using optional audio components"
Please leave feedback

The sub has worked on two different systems now, I'm pretty convinced it has something to do witht the sub pre-out jack, but wouldn't have a clue how to remedy the situation.
It is very rare for the pre-output to be a problem, requires sony tech.
since this is a specialty repair with a schematic.
