Average I would say is about 80 ah for those deep cycle AGM's. I don't think I've ever seen one claim 1000 ah. Not saying they're not out there, I just haven't seen one. I think the most I've seen 120 ah. I think, with that alternator, a good 80 ah will do just fine, but 100 ah well do you better. If you can swing the extra cost. Like I said, you can't have too much electrical. 

I'm not going to tell you yes or no, because I've never personally tried using only 1 voice coil on a sub, so I can't definitely say it's safe or not, but this is my mode of thinking....

A voice coil uses the movement of the cone and the air around it to stay cool. This function is made possible by the way a subwoofer is designed. The cone, the dust cap, the pole vent, the spacing of specific parts, and suspension. By taking a part of the subwoofer out of commission, and expecting it to work in the same way it's designed, I feel like that's a recipe for failure. The motor force is the same no matter what. That motor force is designed to work in line with what the voice coils can handle together. 

My main concern with it isn't if the sub will work. It will. I'm concerned that that single coil will generate too much heat for it to be able to effectively cool itself because it now doesn't have the other coil to help it move the cone. 

Like I said, I don't know if it will or won't damage the sub. But in my mind, if it could possibly damage it, it's not even worth trying. 

I would say, if you have an amp that's 1 ohm stable, but not the electrical to power it, I would rather wire to 1 ohm, and dial the gain way back to use both coils. If you only have a 2 ohm stable amp, me personally, I'd rather run the 2 subs at 4 ohm, and still use both coils.

You're right. as I find more discussions about using one vc it said the same things you just mentioned and will not go that route. as for wiring the subs to 4ohm.. a 2 ohm stable amp can be paired with it? im not sure if that's what you're implying?.

A 1 ohm stable amplifier can play at 1 ohm and higher. (2 ohm, 3 ohm, 4 ohm, and so on).

A 2 ohm stable amp can be used at 2 ohm and higher. You just don't want to use it under 2 ohm. 

Does that answer the question? Or did I misunderstand it?
