Mazda Infotainment Systems - Bose Wiring Present in Non-Bose models?

[muttleytm]

I have a 2013 CX5 touring with a non-Bose Mazda Infotainment system. I'm thinking about replacing it with an aftermarket head unit and a small amp. The amp calls for a dedicated fused line to the battery. That seems easy enough to do, just run a line through where the clutch linkage would go if the car was a manual transmission. However, I know the car also can have a Bose system and I imagine it would have an amp. Looking into it I see that fuse 43 in the engine fuse block is for this amp and is rated at 25A.

I haven't looked or checked to see if position 43 has any power to it. More importantly I don't know if the wring from the fuse block from that position to the inside of the car is present. I figure it might be, even if it isn't used. That way dealers could more easily upgrade to the Bose system.

For that matter I don't know where the Bose system amp is located when present so I don't even know where to look.

I thought I'd ask and see if anyone knows if the wiring is present even if the Bose isn't and where the Bose is located?

Thanks

I think the amp is located under the passenger seat. I have two, both with Bose and there's a heavy rectangular box under both passenger seats.

I'm sure some audiophile will chime in.

Thanks for the reply. As it turns out fuse 43 has no fuse in it nor does it have and contacts for a fuse. I took a look after I posted. I was thinking it might have the wiring if not the system.

Running a line through the firewall won't be hard and the fuse block on the battery has an unused port, however the fuses in it aren't removable so I'll have to attach an inline fuse holder to the wire, but there is a spot to attach it with an M6 bolt to the fuse block.

Pretty sure the wiring for Bose vs. Non-Bose will be different. There are more speakers in the Bose systems, plus the amp wiring (and yes, it's under the passenger seat) so the loom is more complicated - thus I doubt they would/could use the same ones.
