Question about Pioneer PRS-X720 Car Audio Amplifier
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.
