Hey guys I posted a while back, I have a 2014 GMC sierra regular cab. And I currently have 2 JL AUDIO W1v3s. Now the box I was going to make was going to be sealed. A friend of mine has the same box I'm going to build. It's fiberglass back and wood from front, since there's not much room for a box inside a regular cab truck. He has 2 JLW6 12". They fit! So I was thinking maybe a ported box would be good.-I want Sundown Neo Pro 6.5 door speakers and pro audio tweeters. Now the fun part. Would the 2 jl w1 sound louder then 1 8"ported sa sundown? Do sundowns sound good in sealed boxes? Should I get 1 or 2? I want them loud, as volume wise. Stock systen doesn't crank up as I want it. Here's pictures of the box he made.
