I orgionally planed on getting a 20-39 PCI but I'm lookin to building a sub. Would it be possible to build on that can preform better (Louder, not distorted though, and just as if not more clean) for 1000 or less? I'm assuming it's pretty much the same process as building a pair of speakers. I have a plunge router and a circular saw. I can go a little higher as I'm gonna build my speakers myself.
