The specs I read on the Pioneer site say the amp is not 1 ohm stable, so keep that in mind.
It partially depends on the impedance of each voice coil on the DVC subs. If they are dual 4 ohm, and you connect the DVCs in parallel ("+"s together, "-"s together), you could run a sub on each channel of the amp(s). This would put about 200W on each sub.
The other option is to still tie the dual 4 ohm voice coils in parallel, tie 2 subs in series (one "+" to the other "-"), and bridge the two channels of the amp (aka put them in parallel). But this, also, would be about 200W on each sub.
Things get different if the subs have dual 2 ohm, 3 ohm, or 8 ohm voice coils.

Usually an 800 watt peak sub would be a 400 watt rms. Hmmmm. Anyway, just bridge the amp (1x 380) nd keep the gain up enough to stay clean. Watch the sub and turn up gain until it starts to distort, then back it down a hair. Do this with the CD players volume up 2/3 to 3/4 volume with the BASS and treble at zero (bass better at minus 4 or so if you are a bass head! Hope thishelps.

The information I found on the amp is that is a 2-channel and is bridgeable. It is stable in bridged mode to 4 ohms. You should be able to bridge a single 4 ohm sub without damage to the amp.
Hope this helps.

SOURCE: amp comes on running 2
This could be the reason. If you look at the specs for this amp you will see that the continuous power out is rated for 380W bridged. The speakers rated at 450W should be able to handle close to 315W continuous. Now if you split these numbers being you have bridged these speakers, you drive each one up to about 190W continuous. The speakers are being driven approximately by 60% of the rated capability. I personally like to keep it right where you got it, not exceeding 80% of the speakers rated capacity.
Here are the specs for the AMP:

SOURCE: i wired my dvc sub
1. Check if your power cable is of adequate Gauge 2. Try turning the volume down from the amplifier gain level 3. You could even check to see if your battery is on it's way out and just cant feed the amplifier with the power it needs. (very rare case) do the car lights dim when the volume is not really that loud? 4. There could be an error on the way the subs are connected, double check that you have absolutely configured them to run @ 4OHM. could be checked with a multimeter before connecting to the amplifier. 5. Another rare case is sometimes the fuse block expands when it heats up on loud volumes and can have contact issues so try tightening the socket that the fuse goes into. 6. It could also be a problem with one of the sub woofer or even the amplifier. more details might help me better understand the problem, but i hope this helps. dreamsystems
