    That's not a good idea.  You will not be able to control which frequencies are utilized by each speaker unless you also run a passive crossover.  The sub requires a low pass crossover and the "speaker" a high pass crossover.  Whay not just use the amp for the single sub?

     ok thanks

    With DVC 6-ohm subs, the best you can do is wire each for 3-ohms then run the two in series for a total 6-ohm load.  Connect it to the amp in mono (bridged) mode and it will deliver approximately 400 or so watts.  Sounds like you have Audiobahn equipment, which means the ratings are a bit high so it might be closer to 350 watts.  In any case it should be fine, although the amp will not reach its full potential.

    Match the subs with the amp.  Your amp is rated for a 4-ohm load, so you have to get speakers that can create a 4-ohm load.  Or get an amp that will put out closer to your speaker's RMS ratings at the 6-ohm load you can create.  Other than replacing equipment, you get what you get.  If you like the sound, then what does it matter?  If you don't, then you'll have to go shopping (and I suggest you listen to other than Audiobahn if you do.)

    Cheers.
