Sub question

dts3

In high school I had a small side "business" making sub boxes for people. No fiberglass (I graduated before I had the time to get that advanced) but some of them were pretty creative (this is back when recessed neon lights and lexan windows was what everyone wanted). I want to add that it's more important than most people realize to match the box volume to the sub parameters. When I made them I would calculate out the ideal volume from the sub's specs, depending on whether they wanted a ported or sealed box, and I tuned the port dimensions as well. You may or may not be able to get close to ideal volume by picking your sub and enclosure separately. Also, ported enclosures are easier to get wrong. Are you looking for raw bass, or do you care about sound quality as well? For a sub inside a hatch with no separate trunk you may want to consider sound quality as well.

Just keep that in mind.
