I have a persistent noise issue and i have tried everything that i know as well as numerous things that i have researched.
the system is pictured in this diagram below
only change is i have replaced the two RF 500.1 with a MMATS 1400.1
i have 0 gauge going to the back under the truck on pass side. i have nice gold plated terminals on the battery. 0 gauge ground (>3ohms) about 2 foot in length going into dist block and each amps ground (4) coming from dist block all ground from dist block to amp are no more than 2 ft. Power is the same configuration 0 in 4-4ga out to amps.
up front I have
samsung galaxy tab
middle of the road eq
Pioneer Premier deck
all of these are grounded together to a new ground (>3 ohms), all get power from 5 pin relay switched on by switch ign wire. The Samsung feeds teh deck via phono to pioneer rb10 adapter then 1 set of rcas from deck to eq then 3 sets of rcas from eq into crossover then each set of rcas to their respective amps.
the motor noise has been persistent and does come and go. Yesterday i put the 1400.1 on my subs and i now have a ton of white noise through my mids. i have bypassed everthing i can think of and the only thing that changes anything is when i remove the rcas from the MMATS, when i do that the noise up front is reduced almost completely. But nothing i do completely removes the noise.
any insight as to what my issue may be would be great.
