The trim ring is paintable and I use my playstation2 as my dvd player, in which i have it mouted under my seat (not bolted at all, so i can turn it on from the back) and my car has a stiff bounce to it and has never once skipped!

(please note that thes pics were taken right after install, the wires are a little neater now
