F@#& Pioneer!!!!!!!!!!!!!!!

Well, I found the problem. The rca ground jumper wire I had had broke free from the HU when I reinstalled it. The noise is 90% gone now, but its still there. I never had it before this new Zapco amp.

Just my luck that I would get hit with the noise for the short moment the ground came off. In fact, I was running the HU w/o and grounded RCAs for a while, until about 3 months ago when I installed the ground.

Last time this happened to me, I was 1.5 years into the Premier 2 year warranty, and I bought from ebay. I dug up the paypal receipt, and Pioneer STILL fixed it for free, so at least they are good with that:crazy:

How do you like the Zapco 1000.4 compare to the JL Audio you replaced? I am thinking about purchasing the same amp (Zapco).

Well, with all other things being the same other than the amp, I noticed the I had to turn the tweeters down a notch with the Zapco. Other than that, the bridged 300/4 sounds the same as 2 channels of the 1000.4

Help me figure this out:

Today I swapped out my 300/4v2 for a Zapco 1000.4. BUT before I started I disconnected all power to the trunk by removing the Main power wire fuse. I connected the Zapco with the Symbilink transmitter. I am only using 2 of the 4 channels to run my front comps. I set the transmitter to 0db and had the amp gain all the way down. After double checking and triple checking the connections I reinstalled the fuse. Then I went to start my car, you know the moment when you are 1 key turn away from hearing your new gear. I was excited. (I never started the car at any time during install) So, I turn the key to IGN, only to be greeted with a strange constant thumping through the subs. //content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif

I then turned the car off and disconnected the Symbilink transmitter and the remote for the Zapco

Still noise!//content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif

I then turned the car off again and just reconnected the Zapco

Still noise:verymad: So I went ahead and started the car.....

ONLY TO HEAR THE DREADED PIONEER NOISE PROBLEM!!!!!!!//content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif:verymad://content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif

I then bypassed the HU by plugging the Symbilink transmitter directly into my ipod and started the car, no noise.

So what caused the rca problem this time, IDK where I went wrong!

BTW, my last Pioneer did this too, by that was my fault.

strip 16 awg speaker wire about 10" from its jacket

then run a figure 8 pattern around the RCA outputs on the back of HU

then when you get the end of the wrap ground the excess wire on a bolt on back of HU

noise will be gone

Thanks, but I already did that, the problem was the ground came off the HU when I reinstalled the HU. The noise it still there (before there was none), but is bearable for now...

Thanks though
