Yep this is my first time posting here I am waiting for my lev 5 18” to arrive here in Ohio I have drawn up some plans for the box to put them in. they will be going into my ford van I have two HO/alts, four batteries, I have a few different amps but none that I want to keep for these subs so I will be getting new amps. I am going to wait till the first of the year for those and use my old amps until then. I am thinking about 3000.1s for each sub and then adding 2 more 5s in the springtime. My box plans are for 8 cubes each sub slot ports 38 HZs this will be my first ported box design. I will send pics when I get started and will take any advice offered with much appreciation
