ok so i got a set of polk audio momos 12" for free so i put them in ive had them in for about a month now heres my problem when the subs on it makes a ratteling noise but when its off and you push it in and out it goes smooth without resistance or noise ( i have a ported box) then when its on again and you put your hand on the dust cap it stops ratteling and sounds normal again is this sub blown if so is there a way to fix it or is i not even worth it another question is if its not worth it whats your opinions on fi audio 15" either the ssd or the bl or maybe even the q whats your opinions? thanks

 

forgot to mention its only one sub thats doing this

 

is the dustcap loose or coming off at all?

 

no its still on there good

 

How much power are u running. I have seen this before when u use to much power on a ported box. sometimes u can use stuffing in the box and see if that works.other then that thats all i can tell ya with the info u gave.It is easier if i can talk to over the phone to explain.Let me know.

 

i only have a alpine 600 watt rms ampon it which isnt much and that amps gain is turned up half way and the bass boost is around 1/4 of the way if that what more do you need for info?

 

yea screw it i got a new kicker zx 1000 on tha way so now i have another amp to match my zx350 for my door speakers and hopefully a new fi audio 15" bl will be on my door step i'll keep you posted on the progress
