Topic: sub wiring

[ckmoy007]

wanna ask is there any difference wiring a DVC sub parallel and powering each coil with each channel of an amp. example, a 2ch amp powering a DVC sub, bridged to parallel wiring vs. not bridged, each channel powering a single coil. put power factor a side. juz wanna know will the 2nd variant damage the sub in anyway, i.e. in a musical composition, left drum and right drum at diff time, the 2 channel pushing 2 diff coil at 2 diff time seperately. hope u guys understand wat i meant. :D

If you're powering say each voice coil at 2 ohms stereo vs. on parallel 4ohm bridged, I always find the amplifier drawing more at the low impedance stereo mode than on the bridged mode. The amplifier will run out of steam quickly.

Also, you will have to sum mono both Left and Right channel so that both channels get the same signal (not stereo). The tricky part is to set the amplifier gains for both voice coils to the exact same and I would foresee premature damage to the sub and sometimes the amp as well,if we're talking about very high powered subwoofer systems.

There isn't any significant benefit of running stereo on a single dvc sub, so your best bet is to buy a monoblock or run your multichannel amp on parallel bridged.

If you are running two subwoofers, then you may want to run them stereo with some improvement in ambiance but not particularly significant since the subs are close.

i see... my sub is a DVC 3 ohm. i guess i shud rewire it to parallel. thx for the tip.
