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.

sifu can elaborate a bit.. not really understand.. y 8ohms?? sorry newbies..

dual 4 ohms means u can only wired it up @ 2 ohms or 8 ohms

If you use 4ohm mean u better buy a SVC sub...

but if i still want use DVC i can use this setup rite??




another question, let say my amp can supply 2 ohm, do the sub will give different performance when i wire 4 ohm versus when i wire 2 ohm?? which better??

no
there is no significant difference
unless u are competing in a DB Drag challenge

mana ada no diff....2 ohm gives u less resistance and hence amp pumps out more power compared to 4 ohms

audible ? i dun think so

really? try pumping 100rms into a 350rms subbie and 500 rms into the same 350 rms subbie and see...

Have you ever try before?
How you feel?

i doubt you can audit a difference on 200w @ 2ohm and 200w @ 4ohm... if you can you really have a diamond ear...

be fair with your comparison...

cheers...

Diamond ear can hear the distrotion of sub....wahaha..

craziechild: not saying diff between 200@ 2 ohms and 200@ 4 ohms la...
