u/Kitchen-Signature-11

I have a single sundown 12” with a ported box and I just recently discovered that the placement of my box in my trunk can make it louder or sound better. This is what it’s at currently and I would like some recommendations

I guy like 10 minutes away from me has 2 of these in a ported enclosure that I’m interested in. I currently have 1 sundown SA-v3 12” and the spec seem pretty similar on both subs.
