Ok, I can't take it anymore. I have reduced the intermittent horn in my 4333 cab to the bi-amp switch inside. I have cleaned it, made sure the blades contact as well as possible, but notice a problem. When I have a source playing through the horn it appears to produce less output than the other. When I touch the blades of switch (designated to the horn) or touch the surface the blades sweep across more output. The moment I remove the slot screwdriver, less output I had heard of hardwiring, but am unsure how to do so. Can I hardwire just the horns? How do I attempt this?

Thanks for your patience in my insanity!!!!
