hi im going to another comp on the 1st (sunday). ive been running this amp @ 2ohms with my 4 12's. the ams specs are: 1100@4ohm 1800@2ohm 2300@1ohm 3000@ MAX well n e way, i was thinking bout running all 4 12's down to .5ohms. how long do u think i would have b4 the amp went into protection or overheated? i called up PA and they said that they never tested it at .5ohms. thanks.
