So I’m really excited about my first post on T4R forums! I know that I have some questions and that I’ve obviously come to the right place to get some answers. I have just upgraded from a 94’ 2nd gen to an 05’ 4th gen and boy am I feeling spoiled. I love it so far but there is one thing that I am missing about my 94’. I had a pretty good sound system in my 94’ but sold it with the car because I was looking forward to doing a new system in the 05’. Right now, the 05’ has the JBL Synthesis system in it which is less than I had hoped for and I think that I’m ready to do some upgrading. First on the list was obviously to get rid of the head-unit. I replaced the stock unit with the Kenwood DDX-418. To me, it is a pretty solid head-unit and I’m happy with it. What I’m not really happy with is the way that it is reacting with the JBL system. As I’ve learned after lots of research, the JBL factory amp is responsible for distributing all of the sound from the head-unit to the 10 speaker system… This is very important for the tweeters to only handle highs and the woofers to only handle lows. (I’m pretty sure??) So in order to install any aftermarket Head-unit and retain the factory JBL speaker setup, you have to use an adapter like this one…

Metra Online

Well, when I used this adapter, it worked ok for a day or two. After that, it started cutting out in a few speakers until now I am stuck with what seems to be 5 of 10 speakers working. I am getting no sound from the 2 rears, the center channel, or the 2 rear tweeters. As anyone could imagine, this has left me less than satisfied. I’m not sure if it is the metra adapter, the amp, or whatever…
Has anyone else experienced this problem? If so, what can be done to fix it?? I’m beginning to lean towards just ripping everything out and totally rewiring the speaker system. (Component system, replace sub in factory location, new amp, etc.) Does anyone agree with me that this would be the best solution?
