How to: Subwoofer installation

I got rid of my sub. The radio's signal is too janked. Like you said, one song trying to turn it down. Next song, nothing. I replaced that with 6.5 inch speaker in the rear and a 75 x 4 ch amp. I use the front signal to power the front and rear. I need to do a new write up.

Anyone want to buy my JBL sub? I'll include the Styrofoam cut to fit around it

I've noticed this, too. Wonder what's going on? Some songs have way too much bass and other, similar songs have no bass.
 
I did this install on 22 gr86 premium but for some reason when I hook the rca connections up to my amp my door speakers shut off and no sound from subs also I use the dark green remote wire in the middle of the harness for the amp remote turn on but the amp will not shut off
If the door is / doors are open, it will activate the 12V trigger.
 
I had the doors shut but I did have to open the trunk to check the amp does the trunk trigger the 12v to
I don't think opening the trunk triggers the amp. I don't have the car anymore to check it.

I do remember that if you remove the door panels, the car thinks the doors are open, even if they are closed. This turns on the amp and can drain the battery.
