addictions or alpha 1?

Ive done my research and I have came down to two options for my tower setup. a pair of nvs addictions or 2 pairs of titan alpha 1s w/ the reference upgrade. I understand that I will probably not hear the alpha 1s when riding however the main concern for me is whether of the not the nvs is going to drown out my interior speakers and sound schrill around t he boat. hearing tunes when riding is a priority but alot of my time is spent in tie ups where I want to have the best possible sound around the boat. my interior setup is JL w6 sub w/ jl vr speakers

Go with a pro-audio solution (like NVS) and put an attenuation controller to them and you will be fine.

You can always turn down the HLCDs but you can't turn up the car speakers.
