Greetings to all!

I got a brand new Sub from Amazon, it is all connected and energized but still no sound coming out.
I also connected to my living room home-theater to test and no sound at all.

From the Head unit, I install a 2 Farad Capacitor to a Power Ground Distribution Block (to a 500W amp. rear speakers and a 1500W Sub).
I have one GND for the capacitor and another Power Ground Distribution Block for Amp and Sub GND. to another location.

Power = check
Ground = check
Fuse = check
Wiring = check (not faulty, tested with multimeter)

Any advice is welcome! Thanks to everyone in advance for the support!

No I mean the REM wire. It comes from your headunit to the REM spot on the amp. Its a remote turn on wire. The headunit sends it signal to turn on and off with that wire.

Easy way to get it to turn on is jump a piece of wire from the 12 volt positive to the REM post.

Thanks, Popwarhomie for the advice, I thought this wire was for sub-controller (gain/hertz etc) I saw wones at Amazon too but I'm not using any. I'll gonna test, thanks!

According to Pioneer support... their amplifiers automatically select the proper input signal mode, either RCA or speaker level. When the receiver is turned on, the amplifier automatically turns on
When connected to an OEM receiver or a receiver without RCA output and utilizing speaker level output, the amp automatically senses the input mode and powers up in sync with the receiver.

This is what I did. From Pioneer amp to control turn on the cap and sub. It's there make sense? See blue wire in the pics.

It's right guys, the issue is fixed with the REM wire. Turns out that the Pioneer Amp (at least this model) does not turn on auto, as the support says, the head unit has an 'amp' blue wire, when I connected it to my amp REMOTE CONTROL it turned on/off according to head unit state, even the capacitor display also turn on/off with the REM wire.

Thanks, everyone for the great support! 🙏 🥇
