[QUOTE="bdjacks, post: 3579613, member: 581743"] OK, thanks, let me get a bit more specific with other scenarios to make sure I understand myself. I have a Cadence 500HC amp, specs as follows 4 Ohm RMS Power: 2 x 100 Watts @ 13.8 Volts 2 Ohm RMS Power: 2 x 200 Watts @ 13.8 Volts 1 Ohm RMS Power: 2 x 300 Watts @ 13.8 Volts 2 Ohm Mono RMS Power: 1 x 600 Watts Frequency Response: 20Hz - 30kHz Damping Factor: >200 @ 100Hz S/N Ratio: >100 db Minimum THD: I have 2 Infinity 1052w wired at 2 ohms mono, specs- Impedance Dual 4 ohms Peak Power Handling 1000 watts RMS Power Handling 250 watts Sealed Box Volume .75 cu. ft. Sensitivity 91 dB Frequency Response 25 - 400 Hz And I have a single twelve, cadence beast dr, rated at 600 wrms dual two ohm voice coils that I have wired at 4 ohms in a 1.5 cu ft. ported box. So when I leave the amp in the car and I swap boxes around what do I do with the gain? Two questions, multiple choice answers One is the tens at 2 ohms. at two ohms mono, the amp will put out 600 watts, 100 more than the subs are rated for, so do I, A. set the gain per the instructions on the sticky at 34.6 volts, then I am techinicaly overpowering the subs. VS., B. I set the gain for the max that the subs are rated for 500 twrms then it should be set at only 31.6 volts Two is the twelve wired mono and at 4 ohms it should pull around 400 watts out of the amp bridged, so the square root of 400*4 = 40 volts (A) (OR actually the DMM measures the impedance at 4.4 or .5, that would change the volts to 42.4 (B)) OR do I run the 600*2 34.6 figure according to th sticky ©? There is a big difference here. I hope that someone really knows the answers. With my minimal experience, I trust math much more than I trust my ears. Thanks again! [/QUOTE]
