I have a kenwood x-812d(1000 watts rms) amp which is supposed to be stable at 1ohm. i'm running 2 alpine r types with duel 4ohm voice coils, hooked up to run at 1ohm if i turn up the stereo my amp fuses pop after about 2 mins, can anyone tell me what might be the problem
try this...rewire the subs for 8 ohm each, then run them in parellel, for a 4 ohm load on the amp...see what happens, then report back here..............
Indeed... Pulling too much current because of voltage drop??? If voltage drops current must go up to maintain power
ya know, i find that alot of folks post on here and dont even reply back if they find the problem.....not singling out CDT25, just sayin that we offer help (and sometimes even a little BS humor or such) and we never hear back.........Did we help them?? Did we **** them off? did their car burn down to the ground due to one of our ideas?? WTF???
Lol I have noticed that a lot also...what the fuk is up with that?? I mean do you just read what we tell and suggest to you people and then go ask your buddy who "knows his ****" but really doesn't?? Sorry CTD but just saying...not to you but others
Not the jack this thread but just giving that "update" to viking and azn thanks for the help but I had my subs wired wrong, i needed to wire them in a series and i didnt have them in that connection.
My sub amp also just started popping the fuse Monday. I replaced the fuse and it popped this morning. Because the fuse is popping and the amp is not going into protect, I will assume it is an amp problem. I took out the amp put it on my test bench and checked the obvious. Voltage on the outputs is 42-volts and -42-volts. Power supply is working. Still an amp power supply problem. Pushed the volume up and the fuse went. MOSFETS don't intermit, they either work or don't work. They are ruled out. Semi-Conductors don't intermit. So I have ruled out all transistors and diodes. That leaves me with a bounch of capacitors and a couple of transformers. Only two of the caps in the power supply can provide a path to ground. (yes I'm looking at the schematic). And the transformer could have a shorted coil. I'll look at it some more tomorrow
Its the E-Core transformer. One of the windings must be bad. I can see it with the scope. Everything looks normal till I crank the volume. CTD25, The fuse protects the power supply. If for any reason the power supply has to work to hard or do something it is not capable of (in my case suppling power to ground), the fuse pops. I can not diagnose you amp with out seeing it, however any reputable install shop should be able to.
