sound system

hey, ok i have a 97 accord ex with the stock system, the only thing i have added was a cd changer. anyway, lets say i want to upgrade it a little bit. could i get one of those old acura cl bose speakers or maybe some infinity speakers and just plug and screw them in, or does that require me to get a new amp? im not looking for tons and tons of bass or power, just a clear good sound that the cl's and maximas have with their stock systems. also if anyone has another sugestion that can get me to where i want to go... thanks. :smoka:

a new deck usually helps., but any speaker that fits the opening is plug and play, or listen in this case:)
