Hey so most of the amps I have come accross have a little white dot which tell me where the XO point is, but for some reason, the fostage 800a4 amp I got does not have this, anyone have any ideas how to adjust the crossovers.

Aren't the crossovers on either side of the RCA inputs? I think that's what you mean. Just turn the crossovers to lowest possible. Remember at what point the knob is at lowest and then turn until you get teh point to the desired croosover. I hope that's what you mean.

That's my opinion. Take it, leave it, or correct me.

Just think of it like most....is it HIGH pass, or LOW pass.......

What can your mids, or sub handle..... you know, from here UP, from here DOWN.......
