My subwoofer wont power on and it keeps blowing

hi,

time to open up your TR7010 if still in warranty period don't

Give a ring on the dealer or visit the manufacturer website.

if you intend to do it yourself , here are my suggestions:

1) have a notepad
2) remove all the speakers and note down where it is connected
3) disconnect whatever connected to the inputs and note it also
4) power up again, if still fuse blows definitely the fault is in the amplifier
5) try to note down the electronic component/ parts that is mounted on the biggest aluminum that you can see, they are the candidates
6) if you have a multimeter check for shorted components
check for voltages too after you have replaced the shorted electronic components

A good amplifier never produce more than 0.7v on its output.

hope this helps, thanks for using Fixya!
