I recently have decided to invest into my car's audio equipment. I have just replaced the front doors speakers with 450W speakers by Pioneer. I have heard for my year jeep grand Cherokee i also need to replace the stock amplifier underneath the passenger door, is this true and is it hard to do? Also for a full audio effect do i need to replace the tweeters, the rear passenger speakers, and add subs?
