I am looking at getting a set of these and I wanted to know from anyone that has them weather or not they had a port in them or if they were completely sealed. Also what size of speaker fits inside of them, and what is your overall opinion of them I am not looking to get them because they are JDM, but because I am looking for a little bit more bass in the car. Any other suggestion I am open to as well. Thanks

 

I have them in my crx. Made a huge difference from stock !!
They fit only 5 1/4 speakers in them. They have a small port in them as well.. Well worth getting them/They make some great midbass !!!

We had a few sets laying around and put one into a CRX with some 6.5" separates in there. Made the CRX sound much cleaner. BTW, it helps when you have the brackets, shown above, or it's a little tricky getting them to seat correctly w/out them.
