QuestionQUESTION: My amp has been running fine for months. suddenly blew 5 fuses in one day. here is what changed: i run _4_ subs wired parallel.
one of the subs blew (normal for me) I continued with the other 3 subs for 2 weeks until i could replace the one. i put it in and it worked fine
for a day. then without warning fuses started blowing. none of my wiring has changed and all connections are exactly as they were before
replacing the sub. could i have damaged the amp during the 2weeks i was missing a sub? this is my equipment:
4 sony xplode svc 1200w subs
1 powerbass asa 1000.D 2000x1ch
really thick speaker wire
0 gauge power/ground wires
I have two other amps and subs on a separate circuit that are still running and not blowing any fuses. i am thinking that with the 4 subs i was
running at a certain ohm load but when the sub blew it changed the load to whatever 3 subs will be. During this time i did notice that with 4
subs it sounded quite incredible so if one blows it should only be about 25% less boom with the other 3 still hitting but that is not the case,
it actually sounded rather pathetic as if there was only 1 sub doing all the work. I cant figure out why i lost about 75% of my bass with only 1
sub gone. The amp powers up and 4 subs produce bass but as soon as i crank it up the fuse blows imediately, totaly skipping the overload stage
where the little red light supposed to come on.
Did i do some damage by having the load uneven somehow or is it just time for a new amp, i have had it for about 2 yrs. it has generaly been
pushing the same speakers the same way since i got it specificaly for that purpose.
By the way i have already checked all the connections and the whole nine yards with grounds and wires and there are 3 batteries and two
alternators driving my beast so it's not a lack of power here.
Any info would help since i now have 1 brand new sub and 3 used which means at any time another should be ready to blow which will put me right
back here again.
Thank you.
ANSWER: 4 dvc woofers will be wire at 2 ohms or 1 ohm
is the amplifier 1 ohm stable ?
---------- FOLLOW-UP ----------
QUESTION: Yes, 1 ohm stable. Also 4 svc not dvc.
If fets go will it take my sub with it? I was talking to a guy at a shop and half of what he was saying must have been Chinese because he lost me.
Answer4 single voice coils will give you almost the same options
wire only one speaker to the amplifier and test it for 5 minutes
if ok
wire 2 speakers to the amplifier 2 ohms and test it for 5 minutes,
and after that try the other 2 woofers
let me know what happends
pull all the speakers out of the box and test them one by one they
need to read from 3 ohms to 9 ohms
also pusch the center on every speaker and see if there is any noise from the coil
good luck
