First off, let me say I am a straight up newbie when it comes to this stuff. I am more into offroading. I have 95 Bronco I have been working with. I had an old set of 10" JL audios I had in a nissian pickup I had. I sold it but kept the subs,mids and tweeters. Now have decided I wanted to put them in the Bronco. I got these subs sometime in 95. Being military and moving they have been packed up. Anyway, I have done alot of reading on the net on building enclosesures. I have the parts of my box cut out and the holes for the subs cut. I am thinking of porting th box. I have seen on here where guys are asking about the frequincy the ports need to be. Can someone help me with this? Also, I saw some about a loading wall that goes just above the sub box. Can someone explain what it is and if I can use a loading wall with ports? I just want to make my bronco sound good while driveing down the road. I dont turn the radio on while wheeling, makes it hard to hear when you break something.
