Has anyone tried to run this amp bridged into 2 ohms? I know it's not rated for it, but I was just wondering if it would be stable if only running at the rated 360 watts rms that it says it can put out at 4 ohms. Just want to give my two 12w0s a little more kick, but don't want to risk destroying my amp because of it.

You run the risk of over heating since its not meant for it. You wont get anymore power of of it either.

I wouldnt try that. Its rated at 180 watts at 2ohm stereo and bridged 360 at 4 ohms. I have one waiting to be installed in my new car. I was thinking of getting the ID chameleon 2ohm components and getting 180 watts out of it per channel but those components are kind of pricey. I read a review on that amp awhile back and it did 410 or 420 watts bridged at 4ohms where its rated at 360 bridged.

Yeah ur looking to destroy an amp when u try running under the rec(STABLE)ohms.

Well I tried it and it's workin for the time being. I have the speaker outputs fused with only 5 amp fuses and they haven't blown, so I don't think I'm running even close to the current through the amp that it can. I'm also have the amplifier fused with two 15 amp fuses instead of the original dual 20s, just for extra protection. If I understand it correctly, running an amp at half the ohmic output load basically just tries to double the power, thus doubling the current draw. I assumed fusing each output with a 5 amp fuse would limit the output to ~100 watts rms before popping the fuse (P = (5 A^2)*4 ohm), a max of 200 watts rms between the two. Therefore it shouldn't be running the amp even close to as hard as having it full out on a bridged 4 ohm, making me think it should be alright. Does this sound right, or do I just have my head up my a$$?
