Question about Kenwood SW36HT Subwoofer

Speaker blown? How do I open it up to see? And how do I fix it?

Sounds like something might be blown, there is a very intense vibration and rumbling/crackling noise when bass is on. How do I take the covering from off of the subwoofer (without cutting it off) to see the speaker? Or is it some other problem im unaware of?

Try without having the input plugged on the speaker ... to determine if the noise is coming from cable or receiver

Need driver for Logitech Z-340 speaker system.

Sounds like the Subwoofer is blown. Unless you are handy with this stuff, you're outta luck unless you can find someone with the expertise to replace the blown speaker inside. This is not an easy job. If you are up for it you can follow the previously described method for opening it & removing the blown speaker. A suitable replacement can be found at Note that it will need to be mounted differently than the original which is mounted on the rear of the panel.

The replacement must be mounted on the front. It will need some sort of gasket (foam tape or something) between it & the panel. No soldering is required as push on connectors are used. Connect it up after installation and reassemble the unit.

Be aware that there is a possibility that the sub's amp is blown, in which case replacing the speaker is of no use. It would be good if you had some sort of speaker to connect to the terminals once you get the unit open and check that the amp is putting out before ordering a replacement speaker. Good luck!

When i put my ear to the front of the sub, it makes a sound more like a rattling / grumbling than a clear bass sound. Is this normal sub function or is there something wrong?

It sounds like you subwoofer may have a blown speaker.
If it is new, take it back and replace it.

If it's not under a warranty, take the case off and examine the speaker. If you see a tear in the fabric part of the speaker cone, or along the edge... it is a "blown" speaker.

These can be fixed, but you will more than likely have to take it somewhere to get it done. If there is a company near you that does professional car installations, they will more than likely be able to fix it... or should at least know someone who can.

When i turn the sub up it sounds like it's clipping or it is hitting something but if i hold the plastic ports on the back it seems to stop?

Your ports are vibrating. You need to seal them and this should fix this problem. I would use some dynomat around the outside edges of the port to prevent air leakage and to stop the vibration. You may use a bit of silicone on the outside edge of the port too for further protection from vibration and leaks. Good luck.

My blaupunkt rear right speaker just stopped giving out any sound started with a tearing sound at high volumes with bass intensive songs. then next day no sound at all. left speaker works fine. Help...

As shown in the picture double check the vibration flexible wire connecting to the center, you cannot see it on your naked eyes, use tester to prove the connection, use soldering iron to reattached the broken circuit, be responsible for the connection, put in mind that it is vibrating too heavy...

Opened the phone, 4 screw. 2 at the base of the battery hatch, 2 under the speaker cover. Check the contacts between the speaker and the phone's motherboard. Adjusted the contacts and the phone now works

Sounds like your speaker is blown . Is it a stereo? If so you can try switching the balance to the other speaker to see if its only in the one speaker. You can also switch it to mono to see if tat makes a difference. Let me know what you discover and I can help you further.
