I have the sub amp combo, deadening material, aftermarket speakers and [amp, tweeters, and lc2i. I have also spent an excessive amount of time tuning (target voltage and tweaking the hpf/lpf and all that jazz). I haven’t upgraded the stereo or added a dsp yet. My system sounds great as it is now. How much better will adding a quality aftermarket stereo make my system sound?
I have put it off for some time as I originally invested in the lc2i and with everything else i added, the system performs very, very well. I use a flat eq band and high quality audio files already. Will it be a noticeable difference in quality? edit not too worried about a dsp yet, i plan on getting one later on, when i reupgrade the component speakers and speaker amp](https://www.kynix.com/components/ADA4807-Amplifier-Datasheet-Pinout-Circuit.html)
