Hello, been out of the car audio scene for ten years or so. I've sold off all of my stuff over the years, except for two 12" MTX Thunder 7000s (mostly because I paid so much for them) and my two 15" MTX Black Gold subs. Looking for opinions on what to do with them. I used one 12" for maybe 20 hours playtime in a sealed box, the others are brand new never been played. In fact, the only Black Gold I've heard was the 10" I had in my wife's car back in the 90s. So I don't even know if the 15s are a great speaker, I just impulsively bought them a long time ago.
Can these things be retrofitted for home use? Or should I sell them to someone that can appreciate them? If I did sell them, what is a fair (to me, not just to the buyer) price?
