How do you set a Technics stereo graphic equalizer SH-8025 for full bass?

The last 2 sliders on your left control most of your bass. You slide those all the way, and you should be able to shake your walls, providing you have speakers with great bass response. I have the 8025 hooked to a vintage Onkyo tx-4500 receiver through some cerwin vegas (12 inch woofers, 70s model) and I blow my basement away! Hope this helps. D Lansing, MI.
