dont buy anything sony.....except maybe subs......sony is garbage.....they just look nice....I have a rockford fossgate 400S hooked up to two sony explod amp (which i'd liek to change to some DVC amps) and it pounds.....especially if you've got a hatchback (which I dont) it'll pound.... I think the best speakers bestbuy has are the fossgates too....the sony's might be alrite...btu i'd try to stay away from them...... if you do go elsewhere....I've got Memphis speakers which sound nice...but also PPI, baoston acoustics, and jl make great stuff...anywyas hope that helped.....and yo might want to get two amps...one for the speakers as well as oen for the subs.... but if not get a string deck...mins JVC and it's nice..
