alright so I'm new to all this stuff so I'm just trying to figure out what is the max watt speakers I can put into the car without an amp or anything along those lines... I found some pioneer
ts-a6880f but honestly don't know if it will work or not.. anyone that could answer me or point me in the right direction would be greatly appreciated. I also have a pioneer DEH-X65BT deck installed already.

 

Fitting anything with a RMS over 50w without a amp is pointless.

Pioneer TS-A6880F will be a improvement over factory, but you won't reach their potential without a amp.
