Replacing aeware remote on 2006 Outback

The buttons on my aeware remote Tsc-55 are falling apart and i now see that it isn't available to purchase anymore. I'm getting conflicting info on what can replace it easily with the same connections. Anyone do this already? Also i have a kenwood kdc x494 and lately it seems to cut out at higher (not that high) volumes. Would adding an amp fix this and if so, anyone have any recos on which one? I don't need anything crazy, i only have 6 speakers inside the boat and i just want to hear them while towing people...thanks to anyone with experience/advice.

I sent MLA one out of my previous LSV about a year ago. He was planning to do some wiring configuring I believe. You might check with him or maybe he will chime in. He might still have it.

Thx Badfoot. A remote or an amp?

I sent MLA a Aeware remote back in May of 17. Sorry for not being clear.
