i agree why put all that money into a sound system when you could put that into a NEW car....i wouldnt put more than 100 bucks into a sound system (and yes it can be done) than waste money. Why put more money into it? You arent in your car ALL the time so it's almost useless to put a lot of money into it. I'd rather dump 3000 dollars into my house or a better car, or SOMETHING other than a dumb radio
