I have a SI 15 mag that I absolutely love sitting in my closet that was part of my previous setup (the one in my sig).
with my TL I have now I dont want to go that big. I am going to go with a SI BM MKIII and one 5 channel amp (JL HD 900/5) and run a 2 way active front plus sub.
What size are they? If they are 10's pm me about one i may buy one off ya. If they are 12's i would say no more than $100 for the good one and $75 for the one with tape. I could be way off though.
