i put this under the seat. I only have video right now, but won't upload. Best bet is to buy off amazon- everything and find a good installer. You'll save tons.
i bought a pioneer double din and kit to fit, lost the useless cup holders. You get get both for about 250 depending on unit.
I put a 4 Chanel in the front trunk and ran components in dash 4", and 51/4 coaxles in door. Pioneers and mb quart comps.
Makes sure whatever head unit you buy had 5 outputs for sub, 6 if you want one under each seat. So
