Looks good man. I'm glad to hear head unit installs aren't bad on this car. I'm so tired of dealing with 90's cars that have XX and YY running through the OEM head unit. My '97 caddy wouldn't even start if you weren't careful with it.
Does that sub enclosure slide around? It is dumb, but I always have issues with enclosures sliding around. That isn't in a performance car either, to say the least.
Nice install, you'll have to post up what you do with the speakers.
How are the speaker mounts in these cars done?
