does any1 know where i can get carpet to match my factory grey color?

if your talking the dark grey carpet in the trunk, your best bet is gonna be a carpet used to match oem colors.... like the stuff used to cover sub boxes and other stuff like that..... I've found that the one that matches the trunk of the ls is usually a dark charcol color, thats what I use on any of the enclousers I make for the ls... and I would say it matches pretty damn good..... heres a link so you can kinda see for yourself.....

Do what I did. I went to an upholstery shop. Had them match the carpet and the door panels with their swatches. Ordered the material I needed and did my trunk. Carpet for the floor and sides. Vinyl for the sub wall. :)
