4xe does not leave you with much option but to force the premium sound. Leaves a lot of room for improvements. Research shows the 9 ch Alpine amp does not allow any low pass filter or crossover adjustment options. I would start with the weakest link and replace with Alpine PDX or JL amps - with a dedicated sub channel. Replace the sub with a JL. But I don’t want to start drilling in my new 4xe yet.
Stock AUX playback is better than CarPlay or Bluetooth. With AUX (analogue) playback you can control the gain lowering the iPhone digital volume - not ideal in the audiophile world. Outside that your only adjustment option is the equalizer and fader.
What Is your equalizer and fader setting set to?
AUX: Bass +7 /Mid +5/ Treble 0
CarPlay: Bass +4/Mid -3/Treble -4
