ive got mixed results about my new build. i was told to go 7 cubes tuned to 36hz.
im kinda confused because im being told that would be to big for a single 18" hdc3. i have a sundown saz-2000d on it and i know they are underated. i compete in spl but the comps i go to are not burps. its metered on music on 3 different runs and 3 different places in your vehicle. ANY help or input is welcomed... thanks

6.5 cubes @ 34 hz for daily, for comps you may want to tune higher. What are your goals?

getting loud means building several enclosures at various tuning to test what works for your application. I can tell you daily those 18s like space and 6-6.5 would be ideal with 96-104in2 of port area....however with SPL it will change per your application. It may like larger or smaller enclosures and the same for port area.

For easy tuning, you might want to try 2 6" aeos. Start a full length, then trim down an inch or so, then play, and so on, till you have it where you like it.

A guy on audioque's site was using two aeros and a HDC318, he had some records. This was before they changed their site. Guy drove a trailblazer, I think he was on here and some other forums.

He had sub up in the middle, then 2 aeros, one in each lower corner.

6's are a lot easier to find unless you can find someone to make a custom 8

Find yourself a custom 10" flared port, 8" at minimum. Or you could do a pair of 6" aeros that can be found online.

Or just do a big slot port for a lot less cash and the ability to easily make it as long as you need. Are you already able to reach the mechanical limits of your sub while burping it? If not, I'd go with a larger box.
