Hello, forum. After my first attempt to build a sub box (and half failing) I decided it's probably a good idea to do some reading (not that it's too late). My current set up is made up of 2 12" Alpine Type S's, an alpine amp that is underpowering them, and many other sins. However, I'm remedying this mess by switching to just one sub, (re)making a box (once I figure it out), and I've ordered a proper amp to power the sub.
I'll be browsing the forum and hopefully learning a lot.
