That combo won't work.  The sub is DVC 4 ohm, not DVC 2 ohm which is implied in that ad (see http://www.cerwinvega.com/products/mobileaudio/index.html).  You need a SVC 4 ohm for a two channel amp.  The amp will take a 4 ohm load bridged.  I would suggest, however, that you look for a 12" instead of a 10".  And yes, sensitivity is what I meant.

And always double-check manufacturer's sites for specs when shopping online ads.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

stevdart - Just out of curiousity, if he hooked one channel to each voice coil, what kind of load would the amp see?

If each voice coil is 4ohms, and each were wired to a stereo amplifier separately, the amplifier will see a 4ohm load on the left and right channels seperately.

To the original poster: try finding a 12" with Dual 4Ohm voice coils and wire them in parallel to a mono amplifier.   This will produce a 2ohm load, which most subwoofer(mono) amplifiers will handle. and defintely get a class D mono amp in the 300Watt RMS range. IMHO more money should be spent on the amplifier than the woofer or enclosure combined(thats not to say buy a wal-mart subwoofer and crown amp)

Ok I think I will be going with this combination.  Let me know your thoughts especially on the sub.

It would be the amp rating of 115 watts X 2 at 4 ohms.  It would be a stereo sub, I  guess.  ;)

That is one goofy-looking speaker if I ever saw one.  But I can't say I've listened to any Kenwood subs lately.  Can't you find another Cerwin Vega?  I know from experience that they are worth the money spent.

There were a ton of good reviews of it on onlinecarstereo.com.  It has a 93db rating and will goto 400 watt rms, which is probably a little more than I need.   And your right its unique looking.

here is the reason for the googy look?

  • Overlapping ribs on cone surface for improved rigidity and dampened resonance
  • sounds good to me?
