I have already upgraded all of my interior speakers and added a 4 channel amp to power them.

I know its not the best of stuff that I have but its better than noting and it sounds descent for what it is. I do not compete with this system, it is for me only and it is the best that I can afford with the tight budget I'm on. I am not trying to build a sq competitive system but my ears would rather hear cleaner output than louder volume. I am trying to make what I have sound the best and as well rounded that it can.

I have pretty much given up on the idea because I have zero experience with vented enclosures and a ton with sealed enclosures. I thought I would try something new to broaden my horizons is all.

I am by no means a pro, but I'm not a rookie either. I was asking for help before I waste time and materials (which I can't afford to do) trying something I've never done.
