Hello. Having problems with my whole wiring system. I had noise havent been able to check that its gone now. But my problem atm is im getting +5v out of the blue/white remote out of the head unit when its off and when its on. It will turn on my dsp but then the amps wont come on after that.

Well, come to find out or figure out somehow the Boss head unit broke probably by me trying to get rid of all the noise from the altenator. Anyhow looking at new head units now favoring JVC. W/Bluetooth anyone have any recommendations or favorites or cheap replacements let me know.thanks

You can always just tap the switched wire so the amps come on/off with the key. You might get a turn on pop but that should be the worst of it.
