Does anyone know what the amps and watts are for a 2003 Dodge 2500 factory radio with CD player is? My son bought the truck used and it didn't have the information in the manual. He wants to replace factory speaker and keep original Radio/CD palyer. Thanks for you help.

 

stock with the infinity sound system is 50w rms - 100w peak; with out the infinity sound system, 12w rms - 25w peak - both systems run @ 4 ohms.

 

Thanks for the info. Looks like he's going to need a amp.
