I did away with LP filters some time ago. The improvements in radios,
the change to cable years ago, and the digital changeover a few years
back have made TVI only a slight possibility compared to the way it
used to be.
Take it out of the system and see if you really need it. Less
complexity, fewer jumpers and connectors will give you fewer potential
problem spots.
Some people put it at the radio output, some at the amp output, and
some use 2 filters and do both.
