It reminds me of this 350lb older guy I saw in his car at Walmart the other day. I alsmost filmed it but he was taking a hit off his cigarette and would exhale then alternate with a pull from oxygen tank and repeat. My wife yelled at me cuz I was just standing there staring like for real?!?wtf?!? I just couldn't look away though. And I've tried for like 40 pages to tell op to slow down and relax and get a box design. And not tryin to be d bag but obviously a wall is too much so I'd just do oneor two of the 18s in nice box subs up port back. And with the 8k (which I'd be more concerned getting proper wire myself if sig is accurate) can run a smaller box and set gains and still be loud. Walls just aren't for everyone. I personally like myback window too much.
