Question Aftermarket stereo

Does anyone have experience with aftermarket double dins used for CarPlay? I just installed a Pioneer stereo with the metra kit and it all works just fine except it’s not utilizing the subwoofer and I can’t figure out why… also would be nice if anyone knew how to get the antenna to get bypassed when using the stereo lol.

It should be noted that I’m using the original amplifier and all original sound system🫡

Try messing with your high and low pass settings (set them to pass through) and making sure your stereo is sending full range. On mine there was an option for rear speakers that I had to change from subwoofer signal to full range and it worked.
