Need help with enclosure design?

Well I've almost got enough saved up for a fully loaded 18" btl. I have a 2003 extended cab s10 this will be going in. My maximum dimensions are 23.5"(h) x 18"(w) x 50"(l). Those are outer dimensions. This will be powered by a Sundown Audio Saz-3000d into 1 ohm :bigclap: . I was wondering if 6 ft^3 would be fine with that much power with 80 in^2 of port tuned to 30 hz.
