Newbies here, need all sifu help. now i got a amp as spec below(1) can i use it to powered this woofer(2)
(1) amp - adam digital
Maximum power:4 ohms, 300W x 2
RMS power: 4 ohms, 150W x 2
Bridged power: 600W x 1
Total harmonic distortion: 0.03%
Channel separation: 65dB
S/N ratio: > 95dB
Low pass: 40Hz-160Hz
Crossover slope: 12dB
Bass boost: 0-12dB
Frequency response: 10Hz-38kHz
Damping factor: > 200
Input impedance: 20k ohm
Sensitivity input: 230mV - 5V
(2) sub woofer - 12w3d4
Nominal Power Handling 250 Watt RMS
Powered Non-Powered
Sensitivity 87.2 dB
Impedance 4 ohm (Dual Coil)
thanks for viewing and your comment..
In short, no you cannot run them at 2 ohms. Your amp cannot support that load. However, if you wire the voice coil in series at 8 ohms you'll be able to run the sub. However, you amplifier's output will be half at 300w @ 8ohms instead of 600w @ 4ohms.(1) amp - adam digital
