Patrick, you should check out www.hsetrident.com for some sweet tower speakers. I have this enclosure on my Supra and it's very nice (Loud and Clear). You can also get the speaker enclosure to match your gelcoat.
I would say NVS speakers(or make your own) I haven't heard HSEtrident speakers so I can't comment. Make sure to run them with a big clean amp. My personal favorites are Xtant 604X and Diamond D9 100x4, there are other good ones as well. Lights, I have not ran across any good ones that were not homemade. I would suggest 6-8 offroad HID lights. There was an aftermarket company that made a swivel adaptor for racks not sure if they are still in business. I worked with MonsterTower and developed my own. There is a little theme in my post, make your own. I have found you it is hard to get the quality and custom fit applications from many aftermarket companies for many products.
