Question about Car Audio & Video

Important thing is to make sure that the overall impedance to any one channel is never below amp's rated spec. Transistors develop power according to the load that is present to them. The lower the load the more they put out. But if they put out too much power they will exceed their capability, toast themselves, and go to transistor heaven.

This will depend on the amplifiers capabilities.
I will give 2 different scenarios.
#1 Stereo configuration
If the amplifier supports an RMS power output close to the RMS input power of the subwoofers then run the amplifier in stereo mode. For example 150 watts RMS X 4 channels driven at 20-20khz. (If you can provide a model # for the subs and the amp your looking at I can help you further with this decision.
Wiring for this is easy and simply involves matching the connectors for 2 of the channels (Front or Rear) to each of the subwoofers.
#2 Mono Bridged mode.
If the amplifier is lower power but mono bridgable you can bridge two Pairs of channels and power each of the subwoofers this way.
Generally speaking a 2 channel bridgable amplifier will be able to at least combine the wattage of each channel into a single monural channel and in many cases its actually higher.
So you would bridge the front 2 channels into a single bridged mode for one subwoofer. and then you could bridge the read 2 channels into another bridged mono channel for your other sub woofer.
For example if you had bridgable amplifier thats 50 watts RMS X 4 you coudl very likely (Generalization based on quality of amplifier) send 150 watts RMS to each subwoofer.
Again I would need to know what amp you're refering to to provide specific wiring instructions. Many Bridging amplifiers either have a single switch that will send them to bridged mode or you would use the positive + terminal from one channel and the negative - terminal from the other channel or a combination of both.

SOURCE: four of these subs to
Click on the link to view the wiring diagram for your setup:
Four 2-ohm dual voice coil subs, 2-channel amp: 2x2-ohm loads
Four 4-ohm dual voice coil subs, 2-channel amp: 2x4-ohm loads
The 2 positives and 2 negatives on each side of each sub is the Dual Voice Coil wiring terminals. Each voice coil has its own wiring terminals.
