Can I assume that the 09+ Navi headunit also uses the same Alpine amp and speakers? Or is the Navi system made by someone else.
Navi head unit definitely is made by Alpine.
Here is old Navi dvd link:
"https://
store.alpine-usa.com/Hondadvdsales/naviorder.php"
It will still take you to new weblink if you use this old link.
I believe amp is also made by Apline, & speakers are from Pioneer.
I upgraded my OEM 6-1/2" mid-drivers to 2 pairs of
this, but with tweeter/midrange module removed, & keep my OEM tweeters. Midranges open up & match OEM tweeters very well with sound stage slightly recessed as the way I like them. Midbass also are more defined.
