So I took out my stock head unit and replaced it with and in dash XM Alpine. I also installed a Basslink sub.
After a month I still love it but I'm noticing that I don't hear a lot of mid range. The stock head unit had mid adjustment but the Alpine doesn't.
I can hear the tweeters OK, and the sub is fantastic.
Do I need to replace the "OEM upgraded" front speakers or install an EQ or both?
I am thinking of Dynamatting the doors and trunk. Will this help the mid's or just the bass?
