Yeah there is amp on the car already. It is an infinity amp as well. However if you are planning on switching out the stock deck in the car you could run into a little extra money needing to be involved. Since there is a factory amp you might have to buy a by pass for it. Usually the bi-pass cost some where from 50-120 dollars depending on where you go, and pretty much every car stereo shop can get and install one for you. However there is an alternative route in doing that. Sometime just turning the amp on will take place of the bi-pass however it is a case by case deal with turning the amp on compared to the bi-pass. The bi-pass however is the more reliable of the two.
