I'm surprised at 40, but maybe they improved it in the '13s with MFT.
I strongly dislike the stereo in the truck, regrettably there's a lot of stuff I'd like to do that precedes upgrading it. I'm not an audiophile, hell, I was "reasonably satisfied" with the stock Bose system in my '04 GMC Sierra. I *miss* that Bose system. And it was well and truly crap. Just kind of wish my $2,430 upgraded Sony system sounded better than my Klipsch computer speakers ($180), or my SENA Bluetooth headset I use on the motorcycle ($150)...as it stands I enjoy music more from either of those sources. I'm not even asking for the thing to play music very loud, just to play it tolerably at 50% volume.
I may eventually just try swapping speakers and the sub (given that it's low effort), though I think everyone says the real problem is the need for a proper amp.
