Im looking for an amplifier that goes along with the stock pioneer system in my lexus. What kind should i get? How much do they cost?(A brand new one)

 

Are you refering to a amplifier for the speakers or the sub?

Did you want an aftermarket one or just an original replacment (I have one of these that I removed from my car).

Standard sub wont really benifit from more power either will the speakers.

 

ummm idk too much about audio setup. an original replacement would be fine for me.
