You could buy vented fairing lowers for $525 or so from a 20% off HD discounter, e.g. Zanotti's which will have glove boxes. Hog Tunes fairing lower speaker kit angles the speakers toward the rider and includes speakers for about $169 from Eastern Performance Cycles on Ebay. Hawg-wired's fairing lowers kit (no spekers), lists for $170, and is a flush mount.
Glove boxes for non-vented lowers are $105 each list ($85 or so discounted) plus the cost of the Hoppe vents plus cutting of your OEM lowers.
Your bike, your $$$, your decision. Personally, I'd be reluctant to cut OEM FLHTCSE lowers, and I don't care for the aftermarket vents (particularly having read very mixed reports on their effectiveness).
Don't know if HD sells color-matched vented lowers for FLHTCSE's.
Good luck with your project.
