I think I am going to leave it all alone until the Sony comes in this week and the reroute the grounds and set up the amplifier gains at that time. I will report back once this is done.
check out the sticky at the top of audio section, it has a video and a chart to help with determining voltage.
the bt355 only flatten the eq curve coming from the stock radio, good luck with your build.
I will check it out! Thanks for the input. I will move the grounds from both amps change the deck add the DSR1 and set all the gains from there. I will report back once it’s all done.
Ok I found some time today to add a ground back to the battery. I used a 4awg to a splitter to pick up both amps. Is this also going to cause an issue?
I set the gains to 20V on the NVX VADM4 ( set to 2 channel and outputs wired bridged 4ohm) with a 1Khz test tone at 3/4 volume, bike running and bass/treble set to 0 position.
I am still having an issue with it cutting out at high volume. For what it is worth it sounds great and is crazy loud.
I also tried setting the HPF to 40hz on the NVX. Overall Amp being used Ground splitter. Secured three ways to the “loop” in the cab hole.
40 hz is a bit low for the hpf I would set it around 80hz, Did you happen to see the red light come on when it cut out? Might double check the polarity of your speaker wiring and to the amp, your voltage setting on the amp seems ok.just throwing ideas out there, wish I could be of more help.
I did not notice a light. Might have to really watch for it. I am really starting to think it’s time for a new battery. That one is going on four years old but I would have thought the stator would put out enough to keep up. I think I will record min/max voltage at that amp and see if it’s dipping low when it shuts off. Might also do a dc current draw and see if if it’s pulling more than expected current too. Also I will bump up the HPF.
On another note it sounds really good and is actually crazy loud and clear. Those pioneers really put out.
I’ll go through everything again when I have a chance again.
BigRed if you have a voltage gauge on your dash that is a decent indicator of when you are overpowering your stator. Some folks will say it "isn't accurate" but it will dang sure tell you when you overpower your charging system. I have run into that before myself.
I also found that with the current amp I have on my 6x9s it would go nuts if I have the HPF set to below 110 Hz. I experimented many times and found that it caused the rear amp to draw way more current than normal when I tried to push them with the HPF set below that. At 100 Hz I can run it up loud and actually see the voltage gauge drop from slightly above 14 to slightly below 12. If I leave it that way for long the check engine light will come on. Once I set the HPF on those 6x9s to 110 Hz I can crank it till my ears bleed with no voltage drops.
I realize in my case I have an older bike with a weaker charging system but the main culprit is the cheap inefficient amp I am driving my 6x9s with. I can run the fader to the front and crank it till it blows my helmet off with no problem.
I just thought I'd mention this because out on the road we usually cannot hear distortion so we don't alway know it is there and causing havoc.

Good luck.
Good info for sure. I do have a voltage gauge on the dash and it seems to stay at 14.4 but there is some dimming of the lights
