Okay I have been out of the radio game for some time. so this is why I am asking this question. I ordered the underground auto fender pods and got them in. my 6.5 fosgate speaker will not fit in the hole. measured the hole on the pod and it is just a little over 5'', i do not think this is right. along with that there was no hardware sent to mount the pods. so what size hole is neede for 6 1/2 '' speaker.
