I'll start with the basics. I have a jvc deck, infinity speakers and a MTX Thunder404 amp. I also had a Infinity sub hooked up to the amp until a few weeks ago when it was stolen. So now I still have my fronts and rears hooked up to 2 channels before, like I did when I had the sub hooked up. So now the problem... This past week I started getting cracking noises through the speakers, which progressively got worse (however sometimes its fine). It also crackles now even when I have the volume all the way down when turning the head unit on and off. I checked the cabling today and noticed under the back seat that it was fairly wet (where the cables run). I wouldnt think that this would cause a problem, but thought I would mention it. I also made sure all the cabling was secure, and took the ground wire out and made sure the surface of the metal was bare. Any ideas? Anything else I can check? Does this sound like a fried amp?
Thanks for any and all help. It is greatly appreciated.
I tried a few things today that a friend suggested. One was hooking up an MP3 player to the amp to make sure it wasnt the deck, and the other idea was to try one speaker at a time through the amp. At first all the speakers worked fine on one channel, and worked fine with the mp3 player. Then I tried some speakers on a different channel and there was crackling again. BUT, then i retested everything and it seemed to work fine. Now I have all my speakers hooked up how it was, with no noise. So if it isn't the deck, amp or speakers, could there be an issue with the wiring to the speakers? Maybe one of them is shorting out?
