[QUOTE="Fernando Lopez, post: 357, member: 193"] Hi, some help here please!!!! I recently upgraded to a crown macro tech 9000i amp to power my 2 (4 Ohms) Danley TH-118s My previous amp experience was with the EV CP4000s which I figured out. But I am having a hard time with my new amp. I have 2 questions 1) Should I power one sub from each channel or should I bridge the sub to power the subs? 2) If bridge is the answer how do I do it? Anyway this is the back panel: [img]http://www.crownaudio.com/pressart/MAi_dualPort.jpg[/img] [b]and here are the amps specs:[/b] Power Output Guaranteed minimum power in watts at 20 Hz-20 kHz with 0.35% THD 4-ohm Dual (per ch.).................................3,500W 8-ohm Dual (per ch.).................................1,500W 4-ohm Bridge.............................................5,600W 8-ohm Bridge.............................................7,000W 2-ohm Dual (per ch.) / 20 mS BURST.......4,700W 2-ohm Dual (per ch.) / 20 Hz - 20 kHz......2,800W 2-ohm Dual (per ch.) / 1 kHz.....................2,800W [b]Here are the subs specs:[/b] Operating Frequency Range ........................ 40 Hz -250 Hz - 3 dB .................................................................... 28 Hz 300 Hz -10dB Sensitivity @ 1M ............................................................ 108 dBSPL .............................................................. 112 dBSPL @ 100 Hz max ........ (Referenced to 2.83V @1M ½ space, measured as 28.3V @ 10M) Maximum Output ................................. 137 dBSPL/143 dBSPL Peak ............................................. 143 dBSPL/149 dBSPL Peak @ 134 Hz Input Power Ratings ................. 1800 W continuous, 3600 W program Nominal Impedance .................................................................. 4 ohms Minimum Impedance ................................................. 3 ohms @ 67 Hz Recommended Processing ................ 25 Hz HP @ 24 dB/Butterworth Drivers ......................................................... LF 1 x 18'' Long excursion Input Connections ................................................................. 2-NL4MP Enclosure Material ............ 13ply, 18mm Baltic Birch, polyurea coate Thanks for your replies!!!!!
