Amp curiosity

[dog24fret]

I have two DD cm1's that will power 4 hifi12d4's each. My question is how safe is it for the amps to go below recommended ohm load. I thought I could get a 1ohm load but I screwed up I can only get 2ohm or .5ohm loads. So I was wanting to run them at .5ohms if they could handle it. Or if there is a way to get a 1ohm load thanks for any help.

well, if box rise is high enough, you might be able to get away with it

Ya after rise and what not you should be able to get close to 1ohm

Ok I really don't understand what you mean by box rise. How dose that affect amp load. Im not trying to sound like a smart butt just don't get it. I always thought it was the speaker load that only affected the amps. I just don't want screw the amps up. When I got everything I was figuring 4 dvc subs could be wired to a 1ohm load. This way 4 subs would 1000 each with each sub getting 250. With 2 ohm they only get 625 with each sub getting 156 watts. Thanks

Is it possible someone to explain this or link me to a site that can.Or if there is a way to get 1ohm please I want to do this right.

About your only safe option would be an impedance matching transformer similar to this:

I doubt that you could find one that could handle the power you're looking at without being very large and expensive.

For a 0.5ohm load:

I can't find any specs on the amp(s), but it ultimately depends on what kind of low impedance protection they have.

Some amps will lower output, some go into protection mode.

Some could handle it if they are properly cooled.

The ratings are there for a reason though. It usually has to do with the amount of current the circuit board traces can handle (plus the rating of the output FETs, heatsink, etc....).

Box rise occurs based on the volume of the box and such and in a sense increases the resistance your amp sees. You have DD amps which to my best knowledge are solid amps, they can probably be run .5 ohm anyway, and if you wire to .5 ohm the worst that should happen is the amp goes into protect, you see it, and put it back. Protect mode is supposed to 'protect' your amp from frying when presented with too low of an ohm load. so imo go try it, you should be ok.

Thank you sir. I have never ran an amp below recommended specks so just needed someone Else's opinion.
