300DroppinLowz Posted June 10, 2014 Report Share Posted June 10, 2014 Yea well like an idiot i burnt my new subs voice coil already just wanna find out exactly why.. so ive been jamming bass since like i was 15 and just bearly starting (or trying to go somewhat big) im driving a 2012 Chrysler 300 limited and i have a FI audio SP4 15 dual 1 ohm on a sundown saz 5000d.. so my car has a stock 180a alternator which i actually think is pretty cool to be stock but i havent got my batteries in just yet. Was planning on get a few d3100s. I know i know everyone says its stupid to not upgrade your electrical but i just haven't got to it not saying im not planning too but damn things get expensive real quick and i just needed time. So i have my sub wired in series to 2 ohms was just tring to test out the new enclosure which is 5 cubes kerf ported tuned to 32hz. By the way i havent got the amp tuned cause no one seems to have a dd1 or o-scope in houston.. amps gain was set to half and bass boost completely off and within 5 min of jamming the voice burns out... so i asked FI and they said too much of a voltage drop but i thought voice coils only go out for TOO MUCH power.. any input???

Kranny Posted June 10, 2014 Report Share Posted June 10, 2014 why did you set the gain to half? a 5000w amp on a tiny 180 amp alt with NO extra batteries? Link to comment Share on other sites More sharing options...
300DroppinLowz Posted June 10, 2014 Author Report Share Posted June 10, 2014 I thought it would be good for a few minutes at least.. so did i clip it the F out and thats what burnt the voice coil or what? Im already gonna get it fixed just not sure if i should go with FI again or if i should go with PSI for upgrades?? Definitely wont be making the same mistake twice just wanna know exactly what happened?... Link to comment Share on other sites More sharing options...
Kranny Posted June 10, 2014 Report Share Posted June 10, 2014 even wired to 2 ohms, its more like 1.4 ohms. fi's 1 ohm coils are actually .7 a piece. 3500w full tilt on an alt that needs to be twice that size. voltage drop + gain too high = clip city.

Kranny Posted June 10, 2014 Report Share Posted June 10, 2014 get a recone from Fi and tune the gains properly with a dd1 or oscilloscope if you know how to use one. you clipped the shit out of the coil. only reason it went out so fast. either with bass boost/loud turned on, the bass set too high on the headunit, or something else.
