Ok so last wednesday i was leaving a restraunt and my music was on very low volume like 3 or 4 and while i was talking on the phone i heard a strange noise come from my sub kinda like some pops and then the sub stopped working about a minute later it came on again worked for about 30 sec. and stopped again i didn't think much of it because i thought i just blew the in-line fuse(believe that's what it's called) it blows about once every other month because it's 10 amps smaller than what i originnally had so today i weant bought another fuse replaced it and still no bass! do you guys have any idea what the problem could be? i hope i didn't blow my sub also my amp to my sub is recieving power so... any help would be amazing thanks.
i highly doubt you blew it on Volume Level 4... chwck your Grounds and power wire.. Rca's in back of Hu might be coming loose... many things can be the problem... 95% sure it aint blown tho
I hope so i know my RCA's are fine,power and ground i assume are fine since my amp has that green light saying it has power. Anything else i can check?
"and stopped again i didn't think much of it because i thought i just blew the in-line fuse(believe that's what it's called) it blows about once every other month because it's 10 amps smaller than what i originnally had"
i thought it was just blowing because it was a 70 amp fuse and i originnaly use a 80 amp but i can't get an 80 amp fuse unless i buy offline so i just used the 70....did i f$^k up my sub??
Hmmmm try.... Push ur sub in to see if it is blown if it is blown it will make a weird noise when u puch it in and be a lil hard to puch in... hopefully ti aint, but yea when ur fuse blows eva month it is not good...
I just don't understand why you would not upgrade your fuse. You could of had a clipped signal run through and pop one of your voice coils. Just push on your sub and listen for mechanical noise.
Ok,i pushed on my sub and i can hear a faint scratching or popping noise not exactly sure how to classify it but it's quite i had to listen very closely to hear it. is their a physical way to tell if it's blown like if i pull it out of the box is their something i could look at?
it sounds like your sub is blown. to fix it you will need a recone, unless its a cheap woofer and in that case you might as well scrap it. to make sure it is blown hook a dmm up to it and see what it reads. if it is close to the subs original impedance you can look elsewhere for you problem, if not you've confirmed you fucked up.
She is done for. Mak sure you never do anything half @ss when dealing with electronics. Everybody does it once, but twice just shows your an idiot. So make sure to keep this that one time
Do you have a home receiver you can hook it up to to make sure it works? Or you can hook up a battery to the posotive and negative tereminals to see if it moves.
you hook the dmm to the push terminals which connect to the coils. im 99% sure you sub is toast though. contact fi and send your sub in for a recone. dont make the same mistakes again...
sorry I'm a little confused on how to test if it's blown.. it's a dual 2 ohm so there is 2 push terminals on both sides.. would i just hook it up to 1 + and 1 -? what ohm would i look for? it was set up for 1 ohm. Just want to be sure before i contact fi and send it in.
Sounds to me like the coils warped or were forced out of alignment somehow. It doesn't always take too much power to have this happen. It can happen for a variety of reasons such as a DC short or an amp clipping at low power.
i was just going to mention what cam said. i had some woofers make a faint scratching noise if i pushed un evenly on it u have to push dead center on it.
K well i just took my sub out of my box. And the string things that connected to both negative's are burnt and broken not exactly sure how to explain this so i'll take some pics. but if that is the problem how do i fix it?
Ah ha, the infamous Fi Q broken tinsel leads. This is a persistent problem with the old Fi's before they starting using woven tinsels, this is why I told people not to buy them before.
Over excursion would do it, but in order for that to happen you have to be feeding the subs A LOT more power than they are rated for (and the coils would probably overheat first anyways)
Or not have the SSF set right on the amp. SSF should be slightly below the tuning of the box, without it the sub will play below tuning, where there is no resistance from the box.
If your SSF is right you probably didn't do anything wrong, this is just a design flaw of those subs.
