My CHT-10 SHUTDOWN AFTER 1 HOUR OF OPERATING

USE ENGLISH ONLY. THANKS.
When I turn on the amplifier, the subwoofer sizzles must turn off the subwoofer and then it works cht 15 velodyne.
Velodyne Acoustics CHT-15 Subwoofers

WELL TEST IN ON 2ND PC OR TV OR HOME AVR OR HOME STEREO SYSTEM WITH LINE OUT SUB;.
IF FAILS THERE THE SUB SPEAKER AMP IS BAD, AND USING BAD LINE IN CABLES,

NO SOURCE TOLD AT ALL
BUT IF USING THE WRONG LINE OUTPUT JACK, AND NOT FOR SUB THIS TOO FAILS.
do not use full volume as that is as loud as chains saw engine, at 115DB (ear damage warning)

manual is here:

Check your receiver's speaker set up menu and make sure suboofer output is set to ON.

Follow the instructions that apply to your electronics -

Check for blown fuse?

It very well could be the spaker leads hitting the speaker cone.

You could check this by removing the amp section from the back.
Remove the screws at the very edge of the amp panel.

Yes the amp section can be peplaced.

Call Velodyne, the amps are not that expensive.

Some ideas.

Blown fuse in the amplifier section.
Dead amplifier
Dead speaker.

Amp is not that expensive, call Velodyne
