Alrighty, so i finally got my front stage installed. But when i first turned everything on each speaker has just about as much, if not more, static than music output. I tried messing with the Xover setting and such, but nothing seemed to change it.

Amp: Sundown 100.4

HU: JVC KDs100

Mids: AA carbon fibers

Tweets: Seas Prestige 27TFFNC/G (H1396)

I've only tinkered with the speakers playing for ~10 minutes, for fear of damaging anything. I'm at a loss of what could make this kind of noise, to every speaker. makes me think it has to do with the amp?

All of this stuff is brand new. I did plug in one mid, might have done the other i dont remember, to my factory speaker wire from the HU to see them play, but they sounded fine. When i hooked a tweeter to the same location there was some static, i just figured that was from too low of a signal from the HU. All of these plug ins have been >1 min.

All of the RCAs, 1/2 of the speaker wire, 4 gauge power wire, and a remote bass knob wire are all run pretty close together. I've seen that that can effect sound, and i've seen that power wire is so well shielded that it's out of the question now. Is this a possibility?

My suggestion please ... turn off ALL processing and equalization in the headunit and external units before troubleshooting ...

It all is/was. Everything at 0.

crossed over active or passive ??

active

4 ch amp ??

yeah, as stated, the Sundown Audio 100.4

components permanently installed / wired ?? able to run temp wires to headunit outputs ??

headunit rca outupus ?? using front left/right ?? how are you splitting that to a 4 ch amp ??

Amp crossovers?

Have you checked/unplugged your rca's to see what channels and what it follows?

They are in there permanently, i wanted them to be. I had no intentions to take them out, but i can do it if needed.

I've got a sub output, front and rear. rear to channel 1 and 3? (mids) and front to 2 and 4(tweeters). I'm using 2 Knu Eko RCA cables for the 4 channel amp.

M5, i am using the amp crossover settings. im not sure what you mean about the RCAs though.

I turned the car on this morning and it sounded pretty decent, last night when i was messing with them the car was off. It seems to make a difference, I dont know what would make that change though..

///M5 is saying unplug channel 1 and 2 from the amp and see if certain channels are causing the problem, if the rcas may be a problem. This will help you eliminate a couple of things and then do the same thing with channnel 3 and 4 unplugged while channel 1/2 are plugged in.

ahh, i was doing that last night, i dont know if it changed much, ill try that now. It is def. only when the car is off.

Any different combo of RCAs plugged in didnt' change the static. Again, it's only when the car is off. If i turn the car on they sound fine, then if i turn the car from on to Acc. they sound fine for a couple min. then fade back to static. Any ideas?

This in the civic?

If it is only happening when you are only on accessory I'd expect a voltage concern. Gong to have to bypass it to find out. First thing though is measure your voltage in both positions and see.

When you say static is it white noise?

Yes, the civic. I have a stinger volt meter hooked up the the power and ground of my sub amp, which was reading mid to high 12s. But i can check that in more detail for you, and see if i notice any correlation.

White noise like this? http://www.youtube.com/watch?v=IL4Qif1qT1M I would say it's more of bad radio freq. static (im listening to a CD) Ill try and get a recording for you tomorrow, hope that my camera can pick the sound up and what's happening.

Have you tried pluging an iPod directly to the amp?

nope, i dont have one but idk how to plug mp3s directly to the amp. If i knew i could try, what would that prove, if it didnt have any static in the accessory position?

You just need a 3.5mm headphone jack to RCA cable. You can get one for under $5 at radio shack, and if it works that way, it's posible that your headunit might be bad

Is the noise there whether the key is in accessory on or in "driving" position on even with the engine off?

Ok, i had the car running. sounded fine at 14.4V. turned the car to acc. i believe, and as the voltage dropped the noise came. This makes total sense to me considering if the amp receives too low of a voltage then it will start to distort the sound, AKA my static sound? Listening to the noise more closely the music also lessens with the lower voltage. I've never listened/owned a system with the front stage ran off an amp. I'm just not used to this, it's all new to me. i can check the run or accessory position after i get out of class, in a couple hours.

HU should be fine, i didn't mess with that at all, just plugged a couple RCAs into it.

Update: my car only has labeled 1, 2 and start. i was talking about position 1 => accessory, if this changes anything. Im pretty sure it's just from the amp not getting enough power.
