I would suggest not looking at a number but listening to the sub instead....once you have determined the highest volume level you can get out of your front stage, you should be using that volume control setting on your deck to set the gain on the amp channels. Feel free to crank it until you start to hear distortion in the woofer and drop it back a notch.....you may lose a db or 2 but your woofer will thank you for it by lasting longer...

The same as distortion in your front stage......while you are adjusting the level at a certain point it will stop getting louder and you may hear new noises coming out of the box. Things like abrupt clanking or popping sounds will indicate that you have reached the limit for that setup. Pushing it past that point is hard on the woofer and your amp.....

So I'm not sure how to explain it but when I start turning it up it like rattles or something, I don't know how to explain it.
Is that normal? I don't hear any popping, clapping just that sound. I assume it just the speaker moving so fast that you can hear that.
Is it safe when that happens?

couldnt get the link to work. with speakers that have tencil leads old skool. that run from the terminal up to the cone airborn.. when they are flexin away at the higher end. alot of them cant move out of the way as fast as the sub is moving so u get some noise from that. not sure if thats what your getting. most new good quality speakers have them stiched to the spider. or squished between 2 layers of the spider.
You want all different-sized drivers handling different frequencies.
On the subs amp, set the high-pass filter to around 80 hz, and the low-pass filter to around 40 hz, this will keep your subwoofer output between 40 hz & 80 hz. Above 60-80 hz is mid-bass, so play around with it to find the sweet spot. What's a fader switch? Does it say fader, or "master/slave"?

I have never heard of somebody attempting to bandpass a subwoofer before. If you set the low-pass at 40hz, the filter will start to filter out any frequency above 40hz. Then you set the high-pass at 80hz, which will start to filter out any frequency below 80hz. Correct me if I am wrong here but this is not making any sense in this old noggin of mine. Based on the above settings are you not in reality filtering out the frequencies that we want to hear from a subwoofer? The principal of bandpass settings make a lot of sense on a mid-bass driver where you need to filter out the high frequency and the really low frequency where we want the sub to take over, but why would we do that on a subwoofer?
but no since i use my amp when u set the low pass to 100hz lets say. then any higher freq wont play. when you set the high pass for the speakers at 100 then any freq lower will get cancelled out. make sense?

Anyways so it's the Crossover on the Amplifier. It's a 4CH amp.
So I have my two front speakers connected to 2CH on the amp, then my sub connected to the other two channels.
For my Sub I set it to "Low Pass Filter" and put the xover freq at 100hz. On the speakers I set them to "High Pass Filter" and put that on 100Hz. This means that the subwoofer will play all frequencies below 100HZ, and the speakers will play anything above that.
