Hey guys, i'm trying to set the crossover on my Alpine MRV 1005 running an Ultimate Sound Cupric 12 inch sub.

The sub has frequency response 23Hz - 400Hz
Fs 23.2Hz (whatever that is)
Sensitivity 89dB

What do you think would be a good level to set the crossover at? I know a bit about wiring them up but have no idea about frequencies.

The amp has a parametric equalizer, I'm trying to work out what it does and how I should use it, from the looks of things it makes a certain frequency louder, depending on what you choose. Anyone have an Idea of what this should be set at?
I have a copy of the section in the amps manual:

Also, if the amp is running 2 channel to a DVC sub should the switch be at mono or 1+2 ?

 

Up

 

Start with 80hz and work your way down.

I can't help with the parametric, but play with it until it sounds good.

 

Looks like you should use 1+2.

Low pass at 80 is a good starting point for most systems.

 

Thanks guys
I'll have a fiddle with it.
