Remote turn on wire for multiple amplifiers

[pervitizm]

I recently added a 6th amplifier to my setup and every since I've been unable to get all my amplifiers to turn and stay on consistently. I had the amp turn on wire daisy chained off a bus bar. Since this issue has come up I've read online that I'm drawing more current than my radio can provide to all my amplifiers in my system. So I brought a 30/40a relay switch to try and amplify the turn on signal to turn on all my amplifiers and I'm still getting issues with them not all coming on.  

 

I have the relay connected into one of my 4 channel amps and then the remote lead is daisy chained from that amp to all the other amps in the system even with the relay on I'm still only getting 1 am to stay on and the remaining amp are going into protect.  My question is this, should I just have all six amps remote turn on run directly into this relay switch and stop the daisy chaining of the wires to remote turn on? Also should I run a bigger guage wire? I'm currently running a 18/16g turn on wire, should I go with like a 12/10g speaker wire vs 18/16g signal wire?

 

I have pics and video on the following Facebook Group page.

Assuming you have the relay hooked up correctly. (which just to make sure, the higher current source through your relay is coming from the batteries right? (probably PIN 30) not the HU remote wire)

do you have a multimeter? I'd check the voltage on each amp on the remote turn on to see if there's some crazy voltage drop issue on the remote wire causing this. if you checked this before installing the relay then you'll see the same result trends here.

If they are all getting a solid battery voltage on the remote in, then do you have an oscilloscope? I'd watch the voltage at different places as everything gets turned on. Depending on your setup, i could see the raw draw of 6 amps turning on at the exact same time causing some electrical issues. Maybe some amps can't build the class D switching from voltage sag and that's putting them into protect.

Just some thoughts
