Hey, welcome to the site. Your amp placement is kinda cool, up there on the rear deck, but I'd be worried about it getting jacked! Looks like you've got a good start on modding. How do you like your Optima?
My optima is the shit. I have no cap and i blew out my alternator driving. My optima gave me 3 starts let me drive it about 40-50 miles home. When i replaced my alt, it still had juice to fire it up!!! About my amp, my tint is illegal all the way around. You cant see inside but u can see outside =).
