L6 has discontinued the Amplifi line as of 2020, from what I've heard.
I've had every floorboard that they have ever made with the exception of the HELIX(the only model that L6 supports anymore).
The Amplifi 150 kicks lollipop with it's BOSE technology, but took forever to update and would occasionally drop the BT signal(very annoying), but if I would have known that I was going to buy a $300 paperweight, I NEVER would have bought the Amplifi TT model.
I've since jumped ship to greener pastures that actually support their product such as BOSS and Kemper
