Altering Bimini to fit under my tower

[fstaslp]

I want to change the front Bimini poles so that I can raise and lower the Bimini without having to unscrew the front poles.

Right now the front crossbar will not fit under the speakers.

I am looking for either a pole in a pole system or maybe some sort of hing that I can install on the pole so that I can lower or break them when raising the bimini.

Any ideas?
