Yes, the xc1410 is an awesome little guy. It can
not be bridged, but is stable at 2 ohms and works GREAT with 4 or 6 Polk DBs - used that way by many forum members here.
I have two XC1410s pushing 10 Polk DB651s. One that is pushing 6 DBs (1 pair at 4 ohms and 2 pairs at 2 ohms) maybe as loud if not louder than the other (which is pushing 2 pairs at 4 ohms).
Those amps are about as simple and efficient as these things get. There are several great write-ups here by members who are using them, I have yet to hear of one failing. I wouldn't use them for larger tower speakers, but for cockpit 6.5" - you may be surprised how well one XC would work with all 6 speakers. If not - the worst case - it will buy you some time before you figure out what you really want/need. That can be an interesting process.
I have learned that expensive does not always equal
better for my liking. For example, I have a set of tower WS ICON8s powered by WS amp - that cost about 1.5k for the whole set with clamps etc. Yet, I find myself liking my lowly DBs so much more, I have them usually cranked up and the ICONS de-tuned. But that's just what I found works for us, and I wouldn't know it if I didn't try.
I like the idea of a WS tower-soundbar, too, how
@jcyamaharider or
@Julian have theirs set up.
