I am installing 3 Sony XS-L1036 subs into one sealed box. I have a Crunch V-200SE amp to run them. I bought this amp used online and I can't seem to find any info on it. I'm not sure if it would handle a 1ohm load without burning up. I found some specs on a v-200 and a couple other v-drive series amps and they say they can handle 1ohm. Does anyone know anything about this amp? I am thinking of giving it a try and running the subs in parallel to get 1.33ohms. If this doesn't work, do I have any other options? Could I parallel 2 across 1 channel and run the other by itself off the other? Or is there a way to combine parallel/series to get a 2ohm load? I picked up the amp for dirt cheap, so it doesn't owe me anything. I will likely get something more powerful down the road, but for now this is all I have. Any info at all would be great.

Try running this amp in a bridged mono and run the subs in parallel and see if the amp can handle it. The worst thing it can do is go into protection mode. If you try to run two subs in parallel and one by itself in a single chamber enclosure you will end up damaging the subs.... don't do this. All the subs require the same amount of power if they share a comon chamber.

Sorry, I should have mentioned that each of the subs is sealed in its own space in the box, so that each runs in its required 0.7 cu/ft of space. So if I was to parallel 2 and the other by itself, would i get the same volume from all 3? Or would the one by itself be twice as loud as the other 2? And would this damage the amp at all by doing this? Can an amp handle running like this. I will try running all three in parallel bridged (1.33ohms) first, but I'm wondering about a plan B if the amp refuses to run that load. Thanks for your help!  Three 4ohm subs on one amp -- posted image.

you can try running 2 of the in series to get an 8ohm load and paralleling it to single 4ohm to make a 2.66ohm load.
