As for details, I have an 06 SS G85 with a Jensen 2-din HU and stock everything else. Head unit has been installed for about 8 months.

The last few days when I turn the car on the head unit powers up and sounds good for about 20 secs, then I hear a static crackling sound coming from the right door speaker. It only seems to do it when you are in gear and moving and not all the time; it comes and goes. I thought it's just a blown speaker, but sometimes you will hit a bump in the road and the the crackling sound moves to the RR speaker for while. Hit another bump and it starts on the RF speaker again. I'm lost! Anyone ever have something like that happen?

Could the right channels of the head unit have an issue or possibly the stock amp? As for wiring, the head unit mofset is piggy backing the stock GM amp. I try not to play music too loud for that reason so I don't think it was an overpowering failure. Any suggestions would be nice, cause I have no clue what to do other than pull the RF speaker out and replace it to see if it's speakers or not.

 

are any wires touching from the HU install? was it installed securely?

 

I used the Metra 95-3302 dash kit and 70-2103 harness. Everything is rock solid, doesn't budge at all. It was a very tight fit, probably too tight if anything.

 

no idea man could be anything really speaker amp HU

 

i was thinking of putting some of those bose speakers in my cobalt. anyone ever had them in a vehicle? really wanna know if its worth it first.

 

what bose speakers? bose doesnt make anything aftermarket for vehicles

 

Talk about a thread hijack lol. After trying to recreate this static problem, it definitely travels from front to rear so it's not a speaker issue. My guess is the stock amp is starting to take a dump.

My head unit has RCA pre-amp outputs for all channels. I also have an old 5 channel amp and some RCAs laying around. I remember from back in my audio days that 2ohm and 4ohm subwoofers are different and you have to power them correctly. So is all the Pioneer system meant to be 2 ohm and does it matter what kind of amp you power these speakers with? If I have to tear the interior apart to test each component I mise well use the amp I have laying around to test with, as long as it won't kill the speakers.

 

ok let me ask you this... do the tweeters ever give you problems?

 

It's really hard to tell if the tweeter on that door is fizzling too. Unless I can get someone o drive me around so I can put my ear right on it I probably can't tell for sure. It comes and goes, usually lasting about 15 seconds.

Something else I noticed this morning going to work is even if the CD is paused and the volume is turned all the way down the crackling sound is still there, and it doesn't get louder or quieter with the audio volume. It's independent from the volume so that tells me it's probably not the speaker, also because it travels to the RR speaker sometimes.

 

the problem with removing the stock amp and going with the aftermarket one is that the tweeters are going to need a crossover most likely passive. Since they are 2 ohm you will probably have to build one unless you can get ahold of a 2 ohm crossover (a full crossover you can connect to both the woofer and tweeter would be better then just something for the tweeter)

i was thinking you could try using the stock amp for just the tweeters and the aftermarket for the sub rear speakers and front woofers

 

That makes sense. It would solve the issue of the crossover and I wouldn't have to mess with the wiring for those either. You might be onto something! Unless the stock amp is actually the problem, in which case I'm just screwed lol.

 

well maybe maybe not. the stock amp has 6 channels so if the 2 that run the tweeters are good and the other 4 are shot then it would work. but the chances of that are???

 

Why don't u switch the speaks in door into the other door and see if problem moves with

 

Now why would I do a common sense kinda thing like that??

I prefer the wrong way every time, that way I get the most anger and wrench tosses across the garage. lol Good thinking. Since the scratchy noise travels from the front to the rear I have a hunch it won't matter but that's a quicker test.

 

recently mine has been doing the same thing but on the drivers side and it is all speakers including the tweeter. gotta check my wiring first but havent had time yet. hope its not the amp, dont wanna have to worry about 2ohm crossover ****.

 

ya its just a pain because very few speakers are 2 ohm and the impedance affects the crossover slopes so you cant just grab a regular 4 ohm crossover and run it
