not sure what you're asking for...or why they sold you a mono amp with two huge DVC subs...
but here is one way to wire it, if that's what you're asking.


I start with hi or low pass filters set near the frequencies the drivers are rated to handle and adjust from there by ear.

are you asking for advice on amp settings? if so, i personally would just turn it all to the lowest setting and play with it from there.

I agree. Just play a song that is the genre of music you listen to the most and fine tune the settings until you get the best sound. Then you can just use your HU equalizer to further fine-tune if you want.

hey, as long as it sounds good, that's what matters. I don't think it's too small, just thought a multi-channel amp would be used for multiple dvc subs.
