Mounted the speakers directly onto the aluminum siding and brought the wire out through the eave through these feed through bushings from radio shack.
Installing outdoor speakers on vinyl siding.
The vinyl or aluminum siding by itself isn t strong enough to support the weight of a speaker and the bracket will sag.
Connect speakers using banana plugs.
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.
So drill a hole insert an anchor and then bolt the mounting bracket into place.
Siding itself is not strong enough to hold a speaker.
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.
Connected them to the speaker b terminals on my receiver.
To drill into siding go near the top of the siding where it s most narrow.
To install banana plugs you will need to strip the end of the speaker wires.
