Well, my brother bought some Rainbow SLC 265s. So, I'll be the one installing everything, because he isn't mechanically saavy per say. I have a spot for them, but the little black putty type stuff they give me isn't strong enough to holy the tweeter in. It's in his door, so when he shuts his door, it keeps popping out. What have you guys used or what would you use to mount the tweeter? If needed, I could provide some pictures. Thanks in advance.
