no... im using 3 17 ft stinger HPM series 1 2 channel RCAs. they are directional and they are all going towards the amps. im totally befuddled here. i dont have my bass **** hooked up yet. ive been told that it cleans up a lot of noise, so im hopin that will help.

This is what I have figured out so far.
1) The whine is in the door speakers.
2) The whine is ONLY when I have the sub amp powered up also. Does not matter if I have the RCAs hooked up on the sub amp or not. No sub amp, there is no whine in the door speakers??????? got me confused.
I have a distro block for the ground and the power. I was going to change my grounding spot until i unhooked the 500.1 and noticed that it was only in that amp so i figured it wasn't the ground spot.
Any suggestions?

The rcas are down the passenger side sill and the power is down the drivers side. they only cross where the 0/1 ga is running up to the dist block and the rca to the sub is running to the amp. but i still get the noise even when those rcas arent hooked up

I kinda thought the same thing, but im definately no expert. I may have not done enough trouble shooting and be totally off on this as well. Im going to pull the amp today and put in my brand new 500.1v2 and see what happens

OK... I think I have found the problem... I was going to take the amp out and hook up my other 500.1 to see if it was the amp. i took it off the back wall and started up my truck to see how it sounded. NO NOISE!! I attach it back to the wall and I have noise again...
Im assuming that my screws that are holding the amp to the sheet metal are causing the issue????
If that is the case, why is the same thing not happening with the 300.4? its attached the same way.... 1 inch self tappin screws... 1/4 inch masonite with carpet, sound deadening and then sheet metal
Should I redo the amp board with 1/2 inch mdf and use 1/2 inch or 3/4 inch wood screws so as not to hit the sheet metal??
When I first thought about attaching my amps on the back wall I assumed that screwing into the sheet metal would be a bad thing, but I thought that i have seen some pics of amps screwed directly to the sheet metal....
Any suggestions?? Thanks
