2003 260DA speaker sizes

[ppkaprince98]

I am going to be upgrading my stereo this spring like many have already and I need to know the size of the 4 stock speakers so I can order the replacements and fit the same hole. Does anyone know the 2 sizes off the top of their head, my boat is in storage so I cannot access it.

Thanks

According to the parts manual they are 6.5 inch.

My 2003 220 has the same part number and description listed. The speaker cover is way bigger than 6.5". Don't know how they did it on the 260 DA but the rear speakers fit in an opening in the vinyl and I thought small speakers wouldn't look right. I have 2 pair of JL M770 that I will hopefully find some time to put in over the winter.

Here is my opening

Here is what the speaker looks like

The '99-'04 260DAs are not tightly surrounded like that. On the port side it is under the portside lounger cushion.
Yes they are 6.5"
On the starboard side it's behind the helm seat.

They are all 4 ohms correct? Would I have an issue adding 2 8ohm speakers to the stern without an amp? Here is what I want.

A source unit is rated under the most liberal standards possible. If rated similar to a realistic external amplifier power specification then the source unit might be around 16 watts per channel max. Its just not enough to successfully drive that type of speaker especially if you expect it to project a little past the transom. Most home AC stereos are biased for 8-ohms. 12 volt stereos are biased for 4-ohms so they will have far less power into an 8-ohm load. Its another reason that it won't be enough power. You'll find these will not be competitive with the moderate volume of the existing in-boat 6.5" coaxials. You could offset the power loss into an 8-ohm load with a larger external 2-channel amplifier or use a smaller 4-channel amplifier bridged into two channels to run the 8-ohm speakers.
Then there is also the question of how you would drive four regular flushmount coaxials plus another two speakers without an external amplifier added into the equation. A source unit will not tolerate two 4-ohm speakers in parallel for a net 2-ohm load the same way that external amplifiers are comfortable with. You could safely series four speakers on two channels but this would result in the same type of power loss.
Let me know if I misread your objectives. I hate to make it sound complex because its really not. Just covering all the bases for you.
