Is a sealed or ported box better for Type R's? What are the pro's and con's. As you can see in my avatar pic, I have a ported box with 2 Type R 1242's, Lanzar 268 Amp, and a PowerAcousic 5.0 Farad Cap (If I remember correctly. Has been a very long time since I bought the thing!). The ported box hits, and it is pretty good, but I was wondering, because I don't want to go spend alot of money for something that has less quality. Also, how the heck do I set my gain, and what is it? LoL. I have already read the tutorial, so don't refer me there. It confused me, sad to say, because I am a calculus student. Thanks for all the advice!
