My nephew ordered 2 of these subs based on size, price and brand. He already had the amp (Hifonics BXi1610D) which has made it through 3 different system installs, over the years. HIFONICS FOR THA WIN! So we built a slot port box for these subs (around 5cf) and wired them together down to 1ohm on the amp (1600rms). Set the gain just under halfway, for the break-in period. They blew us both away! Move plenty of air and reaches down for those low notes! 5000 songs later he's still turning heads in his Durango. Gain on the amp is now just over the halfway mark and let me tell ya....DAMN! I still can't believe how well they're performing. Stay close to the manufacturer's specs and you will be more than pleased.
