Will an MS275 run 1ohm mono without killing it?

Maybe, with the gains set low and with fan cooling.

Bleh. Foiled again.

2ohms mono would be much safer....

Yes it would , it has a switch in the inside which switches between high voltage and high currentl , I think the red dot indicates high current, but like the guys say , run fans to keep her cool.

Ahh and why do you even need to run a 1 ohm load ?? Sorry but I feel that 1 ohm loads are for comp cars

So why 1 ohm ???

a ms-275 running 4 ohms mono can over heat and shutdown under the right circumstances.
now if you place a MS-275 in a MS-2125 sink with fan cooling I think your 1 ohm rating could be run for a while, with only issue being over current condition to be dealt with....

I had found a DVC 2ohm sub and wanna squeeze everything I can fron a 275. Im extremely space limited and weight conscious or Id just get monster amps.

get two Ms-275's one for each 2 ohm coil it should blast even with low gains and the two MS-275's could fit in a shroud if you can find one.. just a thought...C

I have 2 ms275s.. I was not aware you could have seperate amps run seperate coils on the same sub. Would you have to set the gains with a DMM?

Well in a perfect world yes a gain match must be done to assure equal output from both amps. But at least he could get the amps to run for a while longer than running a single MS-275 at 1/2 ohm per channel load like he was talking about. I have seen others run two Xenon 600.1's into a 12 d elite with dual voice coils.

now if I was him I would only consider a class d amp like those made by PG for the load he wants to run. The amps cost less and live longer, but I am thinking in a perfect world again aren't I ??...

Im not really gonna do that I think. Im gonna keep the 2 ms275s and get rid of the 2125 and 2220. Im not into huge sound, just a good solid old school system.

Besides, my car got a knock today and Im lookin at rebuilding an engine. Need to keep this kind of on the cheap.

Buy a 600 watt Xenon amp and hook up the 4 ohm or 1 ohm load you can do and bump the life out of that woofer, and never worry about heat or load consideration EVER !!! take the easy road use a class D amp and do as you wish with plenty of power that should not get hot and spoil your day...C
