Blown Subs? Options

[6gsillyca]

how can you tell if you blew your subs? i think i might have blown mine but i am not sure. when the bass should be hitting hard the sound the subs make is kind of a wierd rattling/blowing noise. im not sure how exactly to descsribe the sound. it almost sounds almost like when you have a slurpee and suck out all the juice, and your just left with the icy parts, the slurping sound. i know that a bad description but its all i can think of at the moment. also, when i play with the rca cables (take one out/ put it back and take other out) the rattling sound stops somewhat but subs still do not sound as good as they used to.

could my rca's just be shot?

and im not sure if this matters but it used to go through a 1.0 farad cap until the cap ground came loose. they still worked fine for about a month with the cap disconnected until today when wierd sound started comming.

system is 2 4ohm PG xenon 12", 1200.1 xenon, kenwood ddx7017 double din dvd

thanks for all the help

unplug the sub wires that go to the amp, use a double A battery in replacement. hook up the - with - and the + with +, if the sub makes a noise then its not blown. if sub isnt blown then check your amp fuses, if those are okay, make sure your amp ground is secure.

thats a bad test. a 'blown' speaker can still make noises. if the speaker itself is rattling you've probably ripped a seal or knocked the voice coil loose. take the speaker out and check the diaphram (the bendy part in the basket behind the cone but before the magnet.), if the diaphram is ripped the sub is trash. but generally if its rattling its gone already, it'll only get worse.

get your sub and shake it. If you hear something loose, then its probably the voice coil. Since your sub is still making noise, the voice coil should be fine, you probably just made something come loose. I think

Your description soudns exactly like what my stock premium subs sounds like, and they are shot..and I mean shot you can remove the cone from the coil,,but it still plays..like crap

ad other say, try removing it and examin it physicaly
