Extreme Marine Audio in HB

[Quality Time]

Anyone familiar with their work. Briefly spoke with them at the boat show and they do mobile work. I do not need anything exotic just want to put the current system on roids.
If not, any recommendations in Orange County (sorry, not Havasu, Riverside, LA etc.)
Thanks In advance!
