Thank you sir! Respect is earned and you've earned mine!If your head-unit for some reason isn't powering the DSP on and off with it's remote wire, you can have the DSP turned on and off via the ignition switch which is the red wire going into the head-unit.
This isn't recommended, because your head-unit may be powered off while your DSP is on or vice-versa through other means.
If the amplifiers are powering on and off via your head-unit, the 8-pin wire harness on the DSP is wired incorrectly.
I'm too lazy to find a pin diagram for the DSP unit, and there are 66 pages of PXA-H800 manual I don't want to dig through.
However, typically, all equipment is powered on/off by the blue wire with a white stripe called a remote wire from the head-unit.
As for your dedicated ground cable from the battery to the amps, I think the initial issue is with ground between the battery and the car.
Yes, you probably alleviated the problem with your dedicated 0 gauge cable, but you probably used 10 feet +/- 5 feet of expensive cable.
The Big 3 is significantly shorter. Remember to always use 100% Oxygen Free Copper cables.
There is a LOT of Copper plated aluminum circulating around everywhere and these are by far less conductive of electricity current.
Yes my installer guy likes the wire/cabling from KnuKonceptz and I think it's 100% oxygen free stuff.
Yep, my installer guy is familiar with remote powering on of stuff (amps, etc.) as am I so I'm almost certain he has my H800 DSP wired correctly. I'm curious about the folks here that say their H800 DSPs power on with the HU because not only doesn't mine, but the H800 documentation basically says if you don't have this AI cable thing you have to have a RUX remote controller (wired) to power the H800 up or down.
And I know exactly what you mean about controlling the power to the DSP not tied to the HU, for the exact reason you said, to keep from having the DSP inadvertently powered up. I'd have to install a dash mounted power light to let me instantly know when the DSP was powered up. Oh and the chassis ground we used did not show any significant resistance to a 4AWG jumper cable connected to the battery ground post. But I also understand that would not be a circuit carrying much current, the ohmmeter I mean.
Again thank you for your very interesting and useful words!
