Tricky Sub/Amp Wiring Question

So I currently have a 4-channel amp I'm not really using. I'm trying to find the answer to this question online but I can't really find it.
Does anyone know if I could bridge the amp down to 2 channels, (100 watts rms at 2 ohms or something I think) and then take each of those channels to ONE voice coil on a dual voice coil sub? This would effectively give me 100 watts to each voice coil on the sub, so 200 watts rms total. Any ideas?

if it's designed to be bridged. most are but i imagine there are some amps that are not.
it should be labeled on the terminals of the amp.

Its 4 channel so it can be bridged, but it can't be bridged down to 1 channle, i don't think any 4 channels can.
Either way, I could bridge it down to 2 channels and then run 1 channel to each voice coal on a dual voice channel sub. Might try it eventually.

not necessarily. the concept of bridging on an amp means that one channel will handle half of the curve, so say you cut the wave down the middle, one channel will take the parts above the line, and the other part will take the parts below the line. if the amp will not support this feature... which would most likely be listed online or in the owners manual it will not work. so if you tried to bridge it by just running wires from one channel to the other that would be very bad and you would blow the amp. so long story short, either post the model number here so someone could check, or look yourself to find out if it is possible. also, i would assume that the amp is a 4 ohm amp, and by bridging it it would not change the resistance to 2 ohm. finally, if it did change it to 2 ohms the amp would be running a completely different wattage than 200. usually for power amps, when the ohms drop the amp pushes much higher wattage. for instance i just bought a home stereo amp which is essentially the same thing as a car amp and it pushes 120watts at 8 ohms and for 4 ohms it pushes 250. so you really should look into researching your specific amp before you try something that could either blow the amp or the speakers.

Ya I know how it works, I've messed with stereo shit for years now. Almost any quality amp you buy that is multi-channel is brideable. I was more curious as to if anyone had heard of bridging a 4 channel down to 2 and using each channel to push a channel on each voice coil of a DVC sub. It's possible I guess, but not recommended.

i have a two channel bridged running a dual voice coil. it's in a series though, so it just goes + amp/vc1/vc2/- amp

Ya, still 2 channel not what I'm lookin for. Either way, I'm just going to amp all 4 speakers at 2 ohms and modify my door panels in my WRX so I can fit in 6.5". Should be a pretty sick setup, eventually I'll probably get a class D amp and throw in a 10" sub in the back or somethin, should sound pretty sick.
