Color Matching your Stealthbox®:

Some JL Audio Stealthboxes are not designed to perfectly match OEM colors. Some colors will contrast with OEM colors in order to provide a stylish setup. If you are looking for the closest color match, please select the JL Audio Stealthbox® color that is as close to your OEM color as possible and indicate your vehicle's interior color when ordering

Carpet Color Grade Identification
Perfect Actual exact factory color and texture (dye lot may differ slightly)
Excellent Precise color match, different texture
Good Very close to factory shade/tone
Fair Same basic color, different shade/tone
Poor Same basic color, substantially different shade/tone
Contrasts Not intended to match any factory color. Usually black. Good choice if no Good or better color match exists

Message from JL Audio: Our goal is to provide all Stealthbox® products in colors that match well with factory interiors. Because of availability issues with carpet colors, some Stealthbox® colors are not precise matches at this time. The match grades above give you an indication of how precise our color match is for each Stealthbox® model.
