My system:
Pioneer Premier p690ub deck
Pioneer 6200 monitor
generic DIN sized dvd player
Polk MOMO 6.5 components in doors
Alpine Type R 5.25 components in headrests
Pioneer Premier 3004 12" sub
JL Audio 300/4
JL Audio 500/1
I am using one pair of RCAs for the interior speakers and one set for the sub

Ok, I have a set of those Stinger RCA cables that has 4 channels and merges into one cable. My system's volume keeps going up and down and certain frequencies sound like they go out. Sounds like it's coming in mono at times and the vocals sound like they are under water. Also when I turn the balance all the way to the left I still hear a little in the right side and vice versa. Also when I turn off the sub using the head unit it still gets power.

I'm thinking since the RCAs all combine into one wire, maybe the signals are bleeding across through all the RCAs. Also I have the vertical amp rack so the RCA's are at a severe 90 degree angle, so maybe they are crimped? Has this happened to anyone here. I swear I'm not crazy!

 

Bought some from Knukonceptz. We'll see what happens.

 

Bump to see what ya think about it.

 

those symptoms don't sound to me like bad RCAs. It's quite possible
turning the balance all the way to one side isn't intended to silence the
other, only cut it within a specified range. Ditto the subwoofer control.
You'll have to have someone with the same headunit try it out and tell
you what they get.
Loose connections could cause some of the problems, and ones from the
crossover to the woofer and tweeter could cause some strange effects
as those individual components cut in/out.

 

Ok, cool. I checked all of the connections to the speakers and they look good. If not the RCA, it has to be in the amp or in the headunit. Since the RCA's look a little beat up on the ends I'm replacing those first.
