I cant get the slide controls to change any kind of frequency. Can you help?

There is a button that says EQ , if you do not engage the EQ your in bypass mode and there will be no Equalization . So press that button , but turn the volume to a lower level , because when the the EQ is engaged the volume will bump up . And also make sure your connections are correct, stereo out to EQ in . If your not sure if your hook up is correct refer to you Stereo owners manual.

How does the spectrum analyzer work

It's fake- it doesn't represent anything other than the overall level with a completely made-up representation of frequencies.

i have a sherwood receiver and yamaha speakers for outside deck,would this eq work for this?

Depends upon the inputs and outputs for your receiver. Also depends upon whether your receiver supports an equalizer loop. Also depends upon whether you pipe other sources into your receiver or not. Don't take this equalizer outdoors, of course.
