I know this isnt specifically about the cobalt but EVERYTHING on the internet is retarded and i know people hear seriously know their stuff.


I was clipping my sub. (I knew i was doing it- i was tuning my system and OoOo seriously had 10 god damn seconds of clipping!) Then the bass turned off. Wouldnt come back on.


I took the sub out of the box and tested 5 different (functioning) amps and 10 different 9v and AA batteries. I tried them on the terminals and down the tinsel leads, as they looked fine but i was doing it just in case. Sub has NO REACTION - PERIOD!
I push it in and its smooth as butter and snaps right back.
No smell (besides the faint smell it already has)


Does anyone know what could be wrong? I dont want to buy a different sub if this is fine. +Its rated for 400 watts rms and im puttin 350 rms



thankssss





PS- i grew some cojones and noticed if i push the cone in VERY far it will scratch something. im not sure if your not supposed to... but obviously there isnt much at stake right now

 

do you have a dvom? see if the ohms of the sub come out to be close to the advertised ohms on the sub, if not sub probably needs a rebuild or a new one all together. Also push the sub in and listen for any scratching. Amp seems fine, otherwise you would smell it, same with the sub. seems like a connection got lost via fuse or something. Check the fuses on the amp (all of them) and the power wire. process of elimination.

I literally went through so many subs, I still have a set left. 5 months ago I had 3 sets and 2 amps sitting around. I also had 2 different amps powering the same sub. I had lots of fun. at one time I had 4 12" subs in my car running nearly 3500rms and horrible gas mileage

 

Sounds like you blew the voice coil

 

correct me if Im wrong, but if he blew the voice coil, wouldn't the sub still react?. He says there is no response at all..

 

I added a PS and said there was scratching with DEEP pushing (big ass sorround haa) and yeah no reaction at all to any amp or battery. odd rite? i dont have a dvom ill check my audio installer he may lend it



Ill get another sub but if this one was fine id feel stupid

 

Ehh I'm pretty sure a blown coil means no sound..

Btw I can push my sub down very hard and get it to make a scratching noise but it works perfect

 

Ya I just realized that, mine scratch too... Idk.

Wait so OP your amp doesn't have power?

 

if you put a 9v battery on the terminals of the sub and or the tinsil leads and it does nothing then its a blown voice coil. If it moves in or out (depending on polarity) then the speaker is somewhat working.... if thats the case reply and we can go from there

 

^^^ listen to him, he has a dual alternator setup. pounding the block like steve meade.

 

Damn maybe it's just me but it seems like no one listens to anyone but you emp...

 

it takes ***** to put 2 alternators in your car for sounds.. lol also a big strain on your system and loss in hp.

 

I dobut he lost that much HP from the dual alt...he prob loses his power from all the added weight

And how would it possibly strain his electronics??? He basically doubled the electrical output of his car

 

idk man....dual alt. weight for sure though.

 

lol second alternator ~3hp.... added weight ~1k lb

on another note how do you like those neogens?

 

Ha ok then the VC is fried - thanks I guess I pushed her way harder than i thought all this time. It was cool to have all the speakers Clarion but after this, Rockford p3 500 watts here i come.

PS - clarion = sexy paperweight? I wish i could do something with it

 

what kind of box do you have? mind i ask

 

Its an Onix 3/4 inch (i checked) - one cubic foot (internally) - sealed MDF. Its damn sturdy i must say and it doesnt get in the way

 

their pretty good. haven't noticed anything out of the ordinary. great rubber, smooth ride (on smooth pavement ) no road noise. ok in rain.

 

nice... im thinking of trying something other then the 555's but idk i have bad luck

 

I dont want to bring up a week old dead topic but i wanted to thank all who helped and add that its all resolved now



that amp is amazing. no problem pushing that sub to its limit.
oh of course its louder but the SQ is 4x better than the clarion. Didnt think thatd be the result

 

no offence but im not surprised... those are nice amps. i dont really like the look but they are good amps regardless
