Issues with 1ohm load

[Sleezyk]

So a while back I had a 1ohm stable mix amp that I wired to two alpine type a s subs. The ending load was 1 ohm but the amp acted like it was below and went into protect after a few min.

So now I have a 1200w Rockford fosgate prime amp, I have two 12" p3 subs that are dual 4 ohm voice coils... I got the positives and negatives connected to where each sub is 2ohm... Then I got them connected to the monoblock which connects the ++ and -- so that the final load is 1ohm.. I have looked over many wireing diagrams and am certain I have the wireing correct and have even verified it with a meter...

So why the hell da this amp also have issues? It goes into protect for a few seconds on big notes with volume high, and although I don't think is has went into thermal protect yet, it has gotten to 150f on one side of the amp where the mosfets are connected.

I have checked my grounds and made sure it is bare metal... I have added an extra cd power battery to make sure it gets what it needs..

So... Wtf?! Plz help

what gauge wire are you running? pics of your ground? i've seen more than my fair share of people who thought their ground was good and it was actually utter failure.

Sounds like ground or wiring is wrong

Voltage dropping too low

Put a dmm on the amp terminals and play a bass heavy song and watch your voltage plummet!!!

Wwwoooooooo low voltage protect

Where is your gain set at? 1/2 way, 3/4, etc?

What volume do you turn your head unit up to and what is the max volume?
