Hey guys, I bought a new set of Rockford R152-s speakers, I installed them in the car and ran them off the HU for about 2 weeks, then I installed a Majestic amp MA9400SW, this amp puts out ~ 75 RMS where the speakers say they take 40, from everything I have read if I set the gains correctly I should have no problems.
I put the gains on the lowest setting and ran the speakers fine for about 1 week, now in the driver door I hear something that sounds to me (total novice) like a blown speaker, it is somewhat of a tapping noise. When researching the problem I read that it might be over-excursion, and because I am pushing double the RMS through the speakers I thought that I had found my problem, the issue I run into then is the fact that the speakers made the noise at 14 volume on my HU (pioneer AVH-P5000DVD) which goes to 40, so I figured I was not driving them to over excursion at that volume.
Frustrated and confused I pulled off my door panel and played some music to figure out where the noise was coming from exactly. I will try to describe this to the best of my ability so that the pics make more sense. It appears that the glue that holds the front part of the speaker to the red felt piece that is behind it has come unglued, and the front part is slapping against the hard glue and producing the noise that has been scaring me into thinking my new speakers were ruined because of a bad install. If I put my finger in through the back of the speaker (basket?) and put a slight amount of pressure on the front portion of the speaker from behind the noise goes away.
My question is, what kind of glue should I use to repair this, the speakers were bought through ebay so RF is not going to warranty them.
A picture is worth 1k words, so here are 4 pics of the speakers:
Front
Back
Hopefully visible glue line pic (the glue in question is right where the red meets the black)
Me pushing on the back of the speaker (this causes the noise to go away - I notice that the glue is stuck to the red fabric and not the front part of the speaker)
I am very sorry for the lack of technical terms as far as the speaker goes, I do not know what the parts I am referring to are called, I have provided as much information as I have thought of, if you need anything else I am armed with a camera!
