Audio Troubles

[rappo26]

Lookin for some help. My passenger-side front speaker is cutting in and out. So at first I thought it was just a bad connection somewhere. But I noticed that when it cuts out, it only cuts out part of the way... just plays quieter. Almost like the gain for that speaker drops 50% or so randomly. This really has me stumped! Any ideas what's goin on here?

Also, my 12" mtx sub was acting up. There was a loud rattle when I cranked it, almost as if it was cracked, something was loose somewhere. I noticed that in the center of the cone, when I pressed on it the rattle would stop. So I ripped out the center piece out, the problem stopped. Would anyone recommend what adhesive to use to glue the center cap back in place? I'd like to use something that will take the punishment this sub puts out, and won't leak again.

If it helps... My current set up is an Alpine h/u (CDA-9856 - 18-50rms x4)hooked up to factory speaker harness which runs thru factory amp. Speakers I installed are lower-end Pioneers (30rms, 150w peak), which are hooked up to factory plugs c/o Crutchfield kit. And I have a 12" mtx sub hooked up thru a 600 peak watt kenwood amp.

All in my 97 Mounty 5.0 (w/o JBL)

Thanks for the help!

An easy way to troubleshoot whether or not its the speaker itself would be to swap out the front door speaker for the one in the rear, and see if the front speaker still cuts out or if the problem moves with the speaker. If it does, you can bet it's the speaker.

If the problem still persists in the front speaker location, it's likely a wiring issue unless the factory amp is going out on that channel or possibly the head unit. You might consider getting a spool of speaker wire and wiring up the speakers to the head unit rather than powering them though the factory amp.

You can get special adhesive online or at high-end home audio shops for the center caps, but I've seen various types used, including super glue and regular white glue, with no ill effects, though super glue might not ever let it come off again.
