Well i posted the same comment in subs, never saw it here
Hey Shawn, just wondering how is that amp working out for you, it's the cheapest mono amp i can find (future shop). I want to get it but i'm not sure how well it will do. What do you have it running with ? and how is it ?
For sealed enclosures, the DBO can be used to enhance the lower bass region of sealed enclosures. For bigger/fuller bass, adjust the HP FREQ between 35Hz and 45Hz; adjust the BOOST control according to your preference. For tighter-sounding bass, adjust the HP FREQ between 45Hz and 55Hz; adjust the BOOST control according to your preference. For vented enclosures, the DBO should be used as a subsonic filter to reduce overexcursion of the woofers. Set the HP FREQ control 10Hz below the tuning frequency of the enclosure (e.g., 25Hz for a box tuning of 35Hz); adjust the BOOST control to your preference. This will conserve amplifier power typically wasted on frequencies below the tuned frequency of the enclosure.
