alrite.. heres the deal.ive got a '93 integra gsr.. looking at upgrading my speakers..currently have a 10 inch sub in the trunk, new head-unit ect. so the only thing left is speakers.. now, should i initially replace all 4(front and back) with some cheapers speakers..keep in mind, money is an issue, or just replace the fronts with something somewhat kick ass?? will i notice a huge difference with only new fronts and not backs? keep in mind i have a sub...opinions on what i should do?
