Help please!!!

I'm having a problem and need help figuring it out, I'm new here and this is my first thread, so go easy on me //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Anyway, here is my problem:

I've had my audio system in my car for almost 4 years now. Up until recently it has worked perfectly fine. Lately though I will be driving along and out of nowhere my mids and highs will start to have a little static and start fading in and out and within about 10-15 seconds they will just completely die and I'll be left with just subs. If I turn off my head unit (which also turns off the amps) and then turn it back on, it will be ok for a couple of minutes but then start doing the same thing. If I just press pause when it starts fading out (which doesn't turn off the amps) and then press resume, the mids and highs will still be gone. So to get them working I need to turn off the system and then turn it back on after waiting awhile, but they'll still fade out after a few minutes.

So this has led me to believe that my amp is overheating possibly. But the thing is...the system worked perfect for all this time until out of nowhere recently it started doing this. My amp for my mids and highs is located behind my backseat and I'm even tried driving around with the seat folded down to give it better ventilation, but it still fades out and I have to turn the system off.

So is this my amp or my head unit? If it was the head unit then wouldn't all the sound go out, including the subs? I'm just trying to figure out if I need to buy a new amp or what I can possibly do, can anybody please help me?! //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif

Here is my set up:

2 12" diamond TDX subs

2 1200 watt diamond sub amps

1 600 watt 4 channel D5 diamond amp for my mids and highs

2 pairs of 6" diamond HEX component speakers with separate crossovers

A second battery in my trunk (forget what brand)

A super capacitor (stinger as well)

Kenwood head unit

(The second battery and super capacitor are just for the subs, they don't connect to the speaker amp at all)

By the way, in addition to all of that I also was driving around again last night and the same thing started to happen again, so I pulled over and felt my amp and it wasn't even remotely warm at all...in fact it was still pretty cool to the touch...so this just adds to the mystery...

is there ANYONE that can help me figure this out?

The way to solve this is eliminate possibilities. Try running an Ipod as your HU & see if the same thing happens. Or swap the amp. Definitely not heat-related if what you're saying is true.

Off the top of my head I'm thinking it's a connection in the RCA's or spkr wire, maybe a partial short that takes a while to heat up & then has issues. It doesn't really fit the rules of the game but sometimes happens.

Along those lines it's also possible that maybe your crossovers or speaker terminals have accumulated moisture that's creating a high-resistance short like this. I had something similiar once where the door speaker terminals where very close to the edge of the door & some thin-plastic-coated dampening material. As the dampening heated up it became more conductive & would partially short the speaker & create the same problems.

So again, eliminate possibilities, that's the name of the game.
