I got some 4ohm kicker cvts for my doors should I run them off a small amp? I have them hooked to my h/u rigjt now and they dont sound bad what should I do
external amplification is almost always better. You will be able to bring out the actual potential of the speaker and cut down on distortion, enhancing the sound and prolonging the life of the speaker
Not uncommon with those types of head units. A decent external amp will help achieve better clarity at higher volumes. But if you are happy, you don't NEED an external amp.
