location of car radio and speakers

someone among the group has installed a car radio and speakers.

can you tell me how did you pass the wires

where the speakers are placed indoors and outdoors

thank you

good navigation

Although I have heard others say that the speaker cables are present even if this option is not taken, I couldn't find any and ran my own.

On the 458 I placed saloon speakers at the forward end of the settee, above the settee.  The cockpit speakers are behind the wheels facing forward.  I have never understood the standard Hanse location where they face towards the back of the boat, away from the cockpit area.

The Fusion much more expensive than a car radio but I do like the N2K integration.

I removed the sliding stool for the dining table which allowed me to remove the floorboards.  The settees have a recess at the base and I was able to drill a hole in the floorboard in a position that is not very visible.  This gets the cable from the starboard settee base into the bilge area.  There is a stringer (approximately where the aforementioned stool is located) which has a limber hole on one side and I had to drill a matching hole on the opposite side in order to pass the cables from starboard to port.  Once across this stringer I took the cables forward again and was able to get them through the floorboards (I think I may have drilled another hidden hole here) adjacent to the forecabin/saloon bulkhead.  

[Edit: managed to find some pictures showing speaker locations.]

Both sets of speakers are Fusion, although the saloon speakers do not need to be waterproof.

The saloon speakers are MS-EL602   They came with the RA70N as a package.

The cockpit speakers are MS-FR6021 which are their full marine product.

Both are 6" diameter.

As I commented earlier, Fusion are expensive.  You can probably find less expensive speakers but the ones in the cockpit must be marine grade.
