Where can I purchase UMS10A (chrome mount for 10")

[Louis6507]

I have been looking all over online to get this for a BTA10250D I plan on purchasing next week. The two retailers Bazooka links to claim this is a discontinued item and no longer for sale.

Is that true?

I've tried searching around the usual online retailers, and cannot find them anywhere, except for the 8" ones. I assume the UMS10A fits all 10" Bazooka tubes. Why would it be discontinued? It doesn't really make sense, unless Bazooka is retiring all of their 10" tubes for some reason.

I am searching for this, because I have read in reviews that sometimes the straps loosen up. I usually keep nothing in my trunk. If the tube comes loose while I'm driving, I'm sure there'll be damage, at least to the wiring.
