Re: fuses blowing
At 2 ohm, you are drawing more current (or, more to the point, the higher output causes a higher input to be needed).. This means you are driving the amp harder and it needs more juice (well, only if you are trying to get loud.. at low volumes non of this should matter).. Originally posted by Nick358 hi, i have 2 dual 4 ohm alpine type Rs, with a jbl 1200.1 powering them, i jsut recently changed my wiring from series(trash) to parallel in my box then each sub their own channel on the amp, which would make them be on 2ohms right, well anyway question at hand, my fuses have been blowing insanely since i changed the wiring. before i had a 40 AUE fuse(?) and was working fine and it blew i bought a new holder and fuses 60 agu and i ate them instantly last night, so i was thinking of getting a 100amp circuit breaker, would this do the trick or is it ognna keep on tripping, will i have to set up my system back in the old wiring i had, thanks,peace
Now, you say 'instantly'.. what does that mean? You turn on the amp and the fuse blows? or you are listening to music and once you get to a certian 'loudness' the fuse goes? Is it going about the same place regardless of the fuse (when you put in the bigger fuse, could you turn up the volume more than with the smaller fuse?)?
If you are popping fuses as soon as the amp goes on, you have a short somewhere.. If it's directly releated to volume, then you are running fuses that are too small (which means either too small of a power wire, or fuses too small for you amp).. I'm presuming it's a Class D amp? so, I'd guess around 125 amp max draw? Your power wire should be big enough for that (and the manual should actually have that in it someplace, I'd think) and the fuse should be the right size for the wire...
Hope that helps..
