stereo replacement

[JVM225]

So I've been piecing some stereo stuff together, and think I may try to tackle this myself.

Any tips on how to run the wires? I guess with a car its a little more straightforward, with either carpet or something thin covering where the wire needs to go. I am unsure with how to get all the wire where it needs to go in a boat. Will i have to pull cabinets and such?

If your 400 is similar to my 410 then you can do most of it by snaking wires on the starboard side between the helm and the cabinet (if any) in the forward part of the salon relatively easily.
That’s where the stereo wires on my boat run with a stop along the way at the amp that is behind the settee and under the electric panel.
I replaced my head unit in that forward starboard side cabinet in 2018. The new head unit uses a different wired remote than the one that was at the helm so I had to remove the old one and run the wires for the new one. It was fairly easy to do.

I replaced mine with a Fusion RA70N. I used the existing wiring and amp, but replaced the cockpit speakers with Sony Marine. The system sounds great to my untrained ear. Bonus with the Fusion is that it has NMEA 2000 and integrates nicely with my Garmin MFD. The NMEA drop cable was the only new cable I ran. I replaced the Clarion helm remote with a fusion ARX70 wireless remote which nicely covers the old hole in the helm.

I did have to fashion a mounting bezel out of star board, but that's relatively easy to do with simple woodworking tools.

Hi All,
I thought I'd update this. I got them out using a kitchen knife. Just go straight up with something narrow and thin and then pry only to find out there weren't any speakers in there. Be gentle now...

Curious as to what you decided to go with? More Clarion or different like Fusion or JL Audio?
