Can they be manually extended?

yes. I would not buy these again though. They fail to do what they are supposed to.

I don't see why not. I read the operators manual and it said nothing about the limit of extension rods used.

Sure. You just need to ensure the connector and electrodes are not compromised. Adding an extention should be no problem.

I don't see any way that wouldn't be possible, the wires that run from the speakers to the system itself are bare, and just kind-of clip in, so I don't see that being a problem if you need to extend them.

Yes they can, but carefully about their "thin-and-clear-and-dry-bass" style. No plugin can extend that bass.

As far as my knowledge goes, not without custom mods made to attach them. However anything is possible with a little creativity and effort.

I don't have this option on my truck but l don't think that this is a option with these mirrors, you have get out and manually extend them yourself

I don't see why not, because you can role the thread or whatever you are using to make it longer. Instruction tell you how.

I've never had to fully extend it. I will be using it again on Thursday. If that isn't to late to provide you an answer, I will do so then.

You will have to buy a longer extension, you can also put multiple extensions on at one time.

Yes, they can be extended. I extended mine about 10 feet. I am not sure of the gauge of the wires.

The hoses were roughly a foot long, I believe. I don't know about extensions. You probably could, but I doubt it's trivial (I bought these things a some years ago, they were terrible for my small plants, and I threw them away when I moved, so I can't double check for you, sorry).

Yes you can. This is an adapter and it can easily be used with other USB adapters to create a longer extension.

Yes you can, they come with these little clips, and when you extend the cage you just clip the cage together and it makes a whole.

Not with the included locking brackets, they only extend about 8-10 inches out. You would have to replace those with something more sturdy.

No such extension available. Probably can splice it to that length, having the right type of cable.

yes they have to be connected. if the wires arent long enough they sell extensions.
