Hey dude... this is the second time I answer one of your posts... about multimedia stuff...
I'll try not to be mean, but... what I want to say is that your car is prolly still under warranty, some don't mess **** up, give it to a professional, they'll do it right, it might cost you money, but you'll have someone to blame if it goes wrong. Plus, 400$ equipement is not what you want to mess with, right??
The best feeling is beating a Civic Si with an Accent!
