Well, if you have a regular trunk install or a hatch install that is below the rear seat line, then you could do street class. MECA uses a pressure class formula based on a combination of cone surface area and amp fusing to determine if you would be in street 1, 2, 3, 4, or 5. You have 78.5" of cone surface area with one 10" sub, so, you could run 40 amps of fusing in Street 1, 90 amps in street 2, 190 amps in street 3, 390 amps of fusing in street 4, or no fusing in street 5. Your fuse holder will need to be within 18" of your sub amp.
If you have anymore questions, just let me know.
