I installed outdoor speakers polk audio atrium45s about 2 years ago i ran 14g speaker wire from behind the stereo up through the wall into the attic.
Installing outdoor speakers on vinyl siding.
Connect speakers using banana plugs.
To install banana plugs you will need to strip the end of the speaker wires.
If you have aluminum or vinyl siding you ll need to drill through the siding go through the narrower part at the top to the material beneath likely wood plywood or studs to anchor the wood screws.
Connected them to the speaker b terminals on my receiver.
Siding itself is not strong enough to hold a speaker.
Banana plugs connect directly into the speaker wire clips on the back of the speaker and receiver.
To drill into siding go near the top of the siding where it s most narrow.
So drill a hole insert an anchor and then bolt the mounting bracket into place.
These provide a much more reliable connection than bare wire which is essential for outdoor speakers.
