Should I run my equalizer of a line out converter that I installed or of the rear out rca's that came with the headunit. I had everything going straight to the amps using both the loc and the rca outs and the sound was perfect. I then added the equalizer and the sound started fading in and out when i would press down on the accelerator and the clutch.Whenever I turn the ac off I also notice that it starts fading. This happens not only at high volume but also at low volume. I had the input to the EQ coming from the LOC reason being because the rear outputs on my HU almost don't put out enough voltage. There is also a little bit of engine noise but I can eliminate that if I turn down the highs on the EQ. My question is this: Is it ok that I'm using the LOC and feeding that signal into the EQ(I have the LOC at maximum output BTW) or should I go ahead and use the rear output to feed the EQ and then just boost the volume on the EQ ('cause it has a bass knob and a volume knob) The rear uot rca on my HU is not a SUB out. It's the only rca out that my HU has that's why I ended up buying the LOC.

Does your EQ have a line driver incorporated into it? Sounds like maybe not... Some EQ's do have RCA and speaker level inputs to use. But most require RCA (0.5 - 6 volts input signal)
Some of the better LOC's have a gain feature that actually will boost/cut RCA output voltages. The one I am thinking about has a 9.5 volt max output from whatever speaker line input is available. (12-16 volts) It also has a ground loop isolation trasformer and 1:3 gain ratio. This may solve your problems.

It sounds like your present EQ is not getting enough power to it either. The fading audio indicates loss of power either in B+ or ground is poorly connected. Do you have the HU amps for back speakers connected to input side of LOC and not rear speakers too?
Also, when setting up the EQ, want to do more balancing of the output signal by cutting mids (500 - 2,000 Hz) to -3/6dB and a small amount of boost at lows (60 - 300 Hz) and some boost in highs (3,000 Hz and up) The more boost you use, the more chance of getting engine noise. Avoid boosting any band sliders more than +6dB.
Go back over your ground and power lines in the EQ and make sure you have good, tight RCA connections. This may solve that fading issue mentioned.

PS How many amplifiers/processors are you running now off the REM B+ line on HU? Is the HU grounded to chassis? If not, please do so as soon as possible.
