Contribute a bit about DSP, EQ using
muncheno setting
stock speaker, dsp carrozzeria pro-3500a, sub carrozzeria ts-wx120a (YOU FREAKING NEED SUB FOR THIS SETTING TO WORK)
Master volume -15db
Front volume -2db, highpass 100hz-18db, lowpass 17.5Khz-18db

Rear volume 0db, highpass 100hz-12db, lowpass 15Khz-6db

Master volume set on -15db so i can max out my phone bluetooth volume, make sure it output the best, then adjust overall volume on HU side.
Can see i almost tuned out bass/sub from door speaker, all most of the bass will come from that wx120a underseat woofer. so you can fine tune it with included wired control to match your taste.
got recorded 3 video to test sound, but feel like result so bad, but in person will be good.
for refer i still paste the link here.
included song name in the description so you can check out the ori song for 'compare'
