Thank you. That's why I posted under the pic "I would update the pics with username and date tomorrow. I'm currently out of town.

Is this thing 1 ohm stable ? As I typed that I thought to myself "stupid just Google it !"

Not rated for 1 ohm stability but many have been known to handle that load on proper electrical. I know for a fact this amp here has a much beefier power supply than a stock D2

Yea I just did some research seems like it's a touchy amp kind of scary all the things people said about them but with the ability to mod them makes it cool I don't have all that electrical yet to be certain I can feed it

You keep this above 2 ohms you'll rarely have any issues. Main killer of these is under 1 ohm loads and/or low voltage (is that good for any amp?) My advice though would be that if you need a 1 ohm amp buy a 1 ohm amp and not try to force an amp to do something it wasn't intended for just because joe schmo tried it once and it "worked"

so this is yours with upgraded rails and whatnot? so then this amp should not see a 1ohm load right? given everything in this amp is already sort of pushing their limits even before the change

This amp is not "modded" . I refuse to do the mod on any of these . Its pushes the rail voltage past what the output driver chip is supposed to handle. That's what made so many of these "unstable". Might be an acceptable risk for competition but not for daily driving. The power supply fets in this amp are upgraded from the originals . At most the original power supply fets were rated for 75-80 amps a piece and the ones in this amp are rated for 110 amps a piece so the power supply section is definitely more rugged/reliable than stock. These upgraded fets alone will not make the amp produce more power. Just helps make the amp more reliable . It "should" handle lower ohm loads better than stock and several people have used my rebuilt D2's at one ohm daily without issue but I still contend that anyone that needs one ohm stability should buy an amp meant for that.

I agree in was just curious and I wasn't sure if this was your old one or not
