okay so this JL 8 inch sub(http://www.jlaudio.com/8w1v2-4-car-audio-w1v2-subwoofer-drivers-92070) says it should be tuned to 38.0 hz well it has a circle port, but I wanna do a square port so below is the frequency of 38.55 going to make a big difference?? and also I calculated is as one box cause jl's site only gives you specs for on one box, the the port would be like a t shape inside the box
a shop is going to say 1.5 to 2 hours for paint time and then anywhere from 30 to 150 for paint and clear
not to mention primer or sealer cost, but im not 100 percent sure on paint cause it varies everywhere
anything's possible man, as long as your dedicated, and you know I'm sure they have color matching tools out there, well actually they do, that will help, and even professionals sometimes use tools to color match:) good luck
maybe a wax and grease removers or lacquer thinner just be careful it doesn't eat into the door panel, and also is it on the actually door panel or the plastic behind the door panel??
the only other company I would honestly buy that I have liked is diamond audio, i have a pair of their tens from 1999 dropped two 4 ohms i belileve and boy did they hit
