Here's the deal with this. This will be my first setup that I've ever built, for myself. I Have About $150 to spend on this setup. I want a single 15". Now my question is, I'm not concerned about having flawless audio quality, I just want something to add bass to my truck, which is fairly small (ford ranger size). So, I can get a good deal on a 15" rockford Punch, (80$) brand new, OR I can get a more offbrand name (BOSS, Lanzar) 15" for about $60 new. I will not be getting a high quality amp (Plan on spending about $50 on it). So do you think it's better to go with the rockford, or some offbrand name. Also, I have 4 kenwood 6x9's in there right now, running on a pyramid amp, which IMO works jsut fine. Let me know what you guys think. Thanks Oh, and I am going to build the box, but I will be doing a really nice job on it, not just slapping some wood together.
