loading an amp
 

ok first off i have 1 dvc 250 rms, 4 ohm sub.
Rf amp that has min 4 ohm load for bridged mode.(250 watt rms bridged @ 4 ohm)
A pioneer gm-x552 2 channel amp.(150 watt rms bridged @ 4ohm)
Ideally, because i have only 1(and intend on only having 1) 4 ohm dvc sub, I would like to get the most power to my sub.
I could parallel the 2 coils for a 2 ohm load, but am unsure if the PIONEER amp could handle it.(Ive already checked the specs and does not say)

If only one voice coil is hooked up, to create the 4 ohm load, (and 250 rms is drawn) what difference can you expect in sound/ loudness.

Can 1 coil handle this, or is each coil only desgined to handle 125 watts.
I could always just bridge the rockford, and push 125watts to an 8 ohm load.

Im really stumped here on the best method and would appreciate some more insight.

run your amp 1ch to each vc at 4oms

Well if you must you the equipment you have then you could mono the signal into the 2 channel amp run one channel to one coil and the other to the other coil, Figure out which amp has the highest output in 2 channel mode and use that one. Other wise swap your sub out for a SVC 4 ohm driver.

If 1 coil is hooked up, and i choose to use a variable resistor on the other coil, so(that the Q can be adjusted) What rating should it be?

Nevermind...............5 amps

Do not, for any reason, run a DVC sub with only one coil hooked up.....:eek:

There are numerous electrical and mechanical reasons for this. If you intend to keep the sub you have now, you will need to run it off one of your amps with each channel wired to one coil.

Depending which RF amp you have, it might run at 2ohms mono, but we need the model # to tell.
