amp no X-Over

[GU357]

Hey guys.
The X-Over on my amp is no longer working for some reason.
any ideas?
status: when i flick the X-Over to LPF the sub works fine but it ouputs all frequencies and being a 12" woofer it doesnt do a good job putting out low (bass) and high (trebble) at the same time.
when X over is enabled the setting it had before it seems the subs output is now very minimal (hardly vibrates at all)

Do you have an adjustable lpf? may of been turned up allowing to many frequency through.

Depending on the head unit you could disable the Low Pass Filter on the amp then just use the lpf on the headunit.

HU has no LPF adjust. its very strange as everything was working up until a couple of nights ago. the X-over was set to LPF before and i had to switch it to full for it to work. i will rewire it back up tomorrow and run a few tests to see whats going on. as i've already forgotten

I have a feeling you've turned the knob on your lpf up too high, allowing higher frequencies to pass through... check your lpf to make sure it's at 80-120hz~
If it's fine, it could be foobar
