whether you go bass reflex, 4th order or 6th order bandpass...any type of porting. It all depends on the application and install
it's confusing at first... I still don't have any idea how to design a box. lol do you mean what's the difference between a vented and sealed box?
The simple version, typically porting makes it louder and in most cases, people tend to like ported boxes over sealed boxes.
I built a custom box to fit under the back seat of my Sport Trac, and I didnt port it. I have a very basic stereo. I have a head unit and an amp to drive the sub. Still need to change out the factory door speakers. My box works really well and for me I probably wouldn't notice the difference if I would have built it with a port. The confusing part that I didnt understand was running in the 4th or 6th order thing. My stereo isnt anything like what most of the people here are doing. I pretty much dream about those types of stereos. I do understand most of the basics and just recently learned a lesson in tunning the amp in which I didnt. I cooked the amp that I had installed. Nice thing is that a buddy gave it to me.
4th and 6th order bandpass are just types of enclosures. what did you learn on tuning an amp and setting the gains? what's your set up? subs? amp?
My set up isnt there right now seeing that Im down an amp. But however to ensure that I dont blow stuff up (mainly subs and amps), I need to turn the low boost levels down to start on the amp, turn my head unit volume to about 3/4 volume (depending on distortion level) and turn the amp level up from there till just before the point of distortion. Small time guy like me, thats a good way to start. I Have a Alpine head unit and a 10" sony explode sub. Like I said before nothing fancy, just starting out building this over a period of time.
