well i have a small sub with my insignia home theater in my room and seeing as i go off to college in the fall it wont see much use. it says 50 watt max but it can bump now i have my new sony radio in my car with sub outs. if i hooked it up amp-less other than the one in the radio would it work or not even be worth putting in the back seat to raise the bass a bit

 

I wouldn't do it unless you have an awesome way of hiding it, lol. People will think you are a so dumb.

 

its silver it would blend in with the grey seats and id make it easy to hide i could drop the seats and throw in there if need be
