Had some time and looked at my oem tower set up. As per Loudsubz the bracket is no good fro the horn. So I decided to make my own brackets.

1" inch by 42" of sheet aluminum $5
2-3/8 ss nuts .40 c
1-3/8 bolt .10 c
drill $5
x-acto knife

I first did a test bracket. Then adjusted the back end measurement so there is minimal clearance on the sides. Drilled a hole in the end, tapped aluminum with 3/8" bolt and screwed nut on. I will have the nut spot welded to the bracket tomorrow. I trimmed a notch out of the round plastic bracket with an exacto knife so it would fit flush (very easy)

I only brought one speaker home so I hope this bracket will fit in the can. I will use a dremel and a router bit to trim the round plastic mid bass brackets when I get up north on friday. The brackets took about 10 minutes to bend up in a 3 inch vise.
