HiFi cockpit speakers?

[Zing]

I want to upgrade my cockpit speakers. I’ve currently got Bose 131 units, a 1 way with about a 4” cone. Inside the boat I have Sonance 624 model 6.5” 2 way speakers. They are so much better and I’d like to upgrade to something similar. Only the cones will be exposed to the environment as the units will be sealed into the bulkheads.

Has anyone any tips?

Ive just got these https://www.amazon.co.uk/dp/B001588IUK/ref=pe_27063361_487055811_TE_dp_1
as a replacement for some Clarion marine speakers.
For the money an absolute bargain
