I called Kenwood's tech support on this and got no where really. The amp in question is the KAC-9102D mono amp with the dual "channels" on it to connect your subs to. The question I am wondering is if you have two dual 2ohm voice coil subs to use with this amp, and you wired each in parallel so that you have 1ohm going to each of the "channels" of the amp, how does the amp handle the resistance? does it add the two loads together to get 2ohms?

Kenwood said that if you did this, it would see it as 0.5 ohms. However, I know a person who is claiming he ran two Orion p10D2's like, each wired in parallel to each of the channels and the amp did fine. This amp is not half-ohm stable, not even 1ohm stable. So, what's the deal?

Strange as it may be, I am working a TEMPORARY setup with a dual 2ohm and a dual 4ohm to this amp. If it was just one channel on the amp like most conventional mono block amps are, it would be an easy thing... I worked it out yesterday and got a nice 2.67ohm load by wiring the voice coils of each sub in series and then wiring the two subs in parallel. Unless I did the math wrong, that gave 2.67ohms which is good. With this amp though, I dont know what to expect, dont know how it's going to translate the resistance from each speaker at each channel and then put out the right power. The way the guy talked, it sounded as if the amp simply combines the resistance at each channel together.

Anyone know?

It is just a mono amp. It has only one channel. It has multiple terminals for connecting speakers just to help make things easier, but it has only one channel. Whatever you connect to one set is also connected to the second set. Kenwood is correct, your description in the first paragraph would result in a 0.5 ohm load and that will overload the amp. Wire your 2-ohm DVC speakers for 4-ohms each (voice coils in series) and then parallel them to the amp (connect one to each terminal set) for a total load of 2-ohms.

If the guys at Kenwood said that 0.5 ohm will result in an overload, then just take their word for it.
