My left import wont work. How can i fix this?


Make sure your plug is inserted all the way and that there is no dirt or residue on it. Also you can open the volume panel by double clicking on the volume logo in the bottom right of the start menu. Make sure the balance slider is in the middle for the main volume control.
If this helps, please rank me.

How can you bypass a subwoofer amp


If it came actively powered and permanently connected but you do not want to use the supplied amplifier, then you need to disassemble the subwoofer cabinet and disconnect the amplifier from the driver.

My subwoofer IC got burned because i accidentally plug it to a 220v power supply, mine is only 110v i want to know the IC# subwoofer.


Most likely what got burnt is the bridge rectifier in the power supply section of the electronic circuit. This usually takes the shape of either a single 4-legged IC, or a group of 4 rectifying diodes connected in a bridge configuration. If you disassemble the unit to which the power cord is attached & trace the circuit starting from the terminals of the power chord, you can easily identify it. You will need to replace the 4-legged IC or the 4 rectifying diodes.
You will also need to replace the fuse, since it is usually likely that it gets burnt if the unit is attached to 220V instead of 110V.

How do I disassemble + clean Harmon Kardon SoundStick subwoofer?


Check for a Fuse. Mine is an older model and has a Fuse right next to the power cord. It probably has a slot for a flathead screwdriver.
