Nu_South_Audio Posted July 20, 2007 Report Share Posted July 20, 2007 (edited) i got two 15" fi audio bl's fully loaded on a massive audio p3000.1 which is 3000 watts rms @ 2ohms, the problem is my subs are dual 1 ohm (more like dual .75), should i run them @ .75 or 1.5? the manual for the amp says 2 ohm mono or 1 ohm x 2 can anyone help me? i know the fi's can take it but will the amp? i have a kinetik 1400 in the back and stock under the hood with two runs of 0 guage and a stock alt.

Dale Posted July 20, 2007 Report Share Posted July 20, 2007 put one sub per channel (1ohm X 2). running that amp @ .75 ohms might be pushing it Quote Link to comment Share on other sites More sharing options...
Dale Posted July 20, 2007 Report Share Posted July 20, 2007 or bridge the amp, but put the subs in series. that way you get around 2 ohms and get your full 3kw Quote Link to comment Share on other sites More sharing options...
Nu_South_Audio Posted July 21, 2007 Author Report Share Posted July 21, 2007 well the sub are dual .75 ohm so i would have to wire each sub in series, then parallel to get .75 ohm or series to get 3 ohm, right now there at 1.5 in each channel. on the term lab it hit a 146.0 @ 46hz or bridge the amp, but put the subs in series. that way you get around 2 ohms and get your full 3kw Quote Link to comment Share on other sites More sharing options...
BigOso Posted July 23, 2007 Report Share Posted July 23, 2007 youll be safe running that amp at 1.5 because I highly doubt your reactive load is going to be under 2ohms.

roscoe1129 Posted July 24, 2007 Report Share Posted July 24, 2007 with the impedence rise of the subs when they get warm and becouse of the rise from the box you will be fine at .75 Quote Some people need a sympathetic pat... on the head...with my hammer Scientia est Vox "In Nomine Patris et Filii et Spiritus Sancti" DONT BE AFRAID TO USE THE SEARCH BUTTON!!!
