Hello I have the standard 2002 Mach Sterio and want to add an amp and a sub to it. My sterio works fine and I see no need to change it. I am thinkin of getting a DVD player but between racing and watching I cant make up my mind. My ass end gets squirrely so the extra 60 pounds over my axle really aint much concern to me. I would also like to know if the stock decks have input/output jacks for amps. I know I have three stock amps in my car now and just need to know what the hell to buy to make it work. If not I have to pay some dip shit to do it and end up spendin a G on the damned head unit I want. It is bad ass though. Please help me.
