Question about US Amps MD3D

[streetbeater07 10+ year member]

I am purchasing a md3d for 3 12's and was wandering if it will be ok to run the amp at .67 ohm. i know i can go with dual 2's and series them to 1.3, but after box rise and all it would probably end up a lot closer to 2 ohm actual. Dual 4's wired in parallel would be alot closer to 1 ohm but i dont want to risk frying the amp. What do you guys think would be best? thanks

subs are going to be re se 12's, kicker cvx 12's or something of that nature....havent really made a definite choice yet..any recommendations?

wats the elctrical look like?? should be ok if electrical is sufficient...ho alt...rear batt...dual runs is a plus!!

thanks! thats exactly what i needed to know. i have dual 1/0 to the rear, dual yellowtops in rear, and ordering a 250a alt soon. so it should be fine to run it at .67?

if the yellowtops are g31...more than enough... .67 daily should do well..carefully wit gains...gets a lil touchy at that impedance

You'll be fine when you get that alt //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

After imp rise it will be about 1-1.5ohms and its stable at 1 ohm so it should be fine.
