for mr.babin and anyone who can explain this question about bleed through
 
bleed through problem between rear and front channel on a 4 channel amp if i hook up the rca's to the rear channels with no speakers hooked up and instead on the front channels 2 speakers hooked up but with no rca's connected is it normal to hear rear channel rca bleed through coming from the speakers on the front channels.

if i reverse the order same thing happens.

all channels operate correctly its from a soundstream reference picasso i somehow corrected the problem with low output on one channel don't know how but the only problem i noticed now is the bleed through with the front and rear channels the sound is very faint ( you have to put your ears right on the speakers to hear it).

It's called crosstalk and it's normal but not generally a problem.

thanks for saving me from ripping apart the amp again for the 100th time
 
thanks for saving me from ripping apart the amp again for the 100th time. one more question

my dc offset is 0.3mv, 0.0mv, 2.8mv, and 1.3mv does this in anyway affect the channels not being balanced or is this normal for an amp to not have equally same dc offset?

The offset is determined by the individual components. Slight differences in the various components will cause the offset to vary. It's nothing to be concerned about unless the offset is excessive (there is no excessive DC offset in your amp).

thanks i'm glad to hear the nightmare if over and will never ever take apart a working amp again. i have to keep that in my head to never fix what's not broken unless you want it to be broken.
