i have a pioneer 5200t amp 760watt amp and a pioneer champion series 4 ohm dvc sub rated at 400 rms. the amp puts out 380 watts at 4 ohms bridged, how do i wire the sub to stay at 4 ohms to take the power?

 

Here you go. Hope this helps.

Your amp shows that it can run at 8 ohms bridged.

 

i have it at 8 ohms right now and it doesnt seem all that loud, but its in a sealed box. i want to keep it at 4 ohms for the full 380 watts.wouldnt it be only 190 watts at ohms?

 

This may seem like a silly question but, are you using the Left Pos. and Right Neg. amp terminals for bridging?

Do you have the speaker wired like the link shows?

Amp Pos. to 1 sub Pos.
Amp Neg. to 1 sub Neg.
The leftover Sub Pos. & Neg. Jumper together.

 

You didn't specify the model # of the subs. Is this the correct sub?

This sub is offered in 2 4ohm coils or 2 2ohm coils. If you have one sub with 2 4ohm coils then you can't wire it for a 4ohm mono/bridged load. You can only get 2 or 8 ohm load out of one DVC sub.
If you have 2 2ohm voice coils then you can have 1ohm or 4 ohm with a single sub.
I you have the 4ohm per coil version then all isn't lost. You can still get a 4ohm load if you have 2 subs with 2 4ohm coils. Just wire the 2 coils on each sub in paralell then wire for 2ohm then wire the 2 subs in series for a total of 4 ohms.
