What kind of ohm load will (2) Dual 6ohm Voice Coil Subs present to a Mono amp if wired for low impedance by connecting the voice coils of each driver in parallel (+ to +, - to -) and the drivers themselves in parallel (+ to +, - to - )?

also what kind of load will (2) 3ohm 6.5" Midbass Drivers present to a 2-channel amp?

The subs will give you a 1.5 ohm load but as far as the 6.5 are you bridging them to one channel or using 2 channels?

Well each channel would have a 3 ohm load. If you add the load of both of the channels combined you would have a total of 1.5 ohms between the 2 channels

If you have (2) 4 ohm loads and wire them together then you end up with a 2 ohm load. So you no longer have a 4 ohm load if you wire your 2 subs together. Your amp then sees that 2 ohm load and since its bridged cuts the ohms in half and you end up with a 1 ohm load. So if your amp is not stable @ 1 ohm you will have problems. From the ratings you give the lowest independence you can have with the subs wired together would be 4 ohms. Then the amp cuts that in half for a total of a 2 ohm load on the amp. The best you can do with a SVC 4 ohm sub is wire it in series for a total of 8 ohm load when wired together.
