I know this may sound stupid, but how would I go about getting it fully loaded. Does that just mean selecting all available options, or do I need to call and say I want it fully loaded. The main thing here is the amp I have is 1500 watts rms ( more like 1600 watts true rms). Its old but still powerful. The new 2000.1bd from roford are only 1500 watts at 2 ohms also. I paid 120 for the amp, as i traded an old surround sound with it too. It was a good deal I rly couldn't pass up. Reason I say all this is because in the future the amp might break or, I just might want more power. Since I have the kit so it will run 0 gauge wire and all that Id like to just have one sub, and not worry about having to upgrade when the time comes. Simply swap the amps. My biggest downside is that I have to buy the sub for 2 ohms as its the lowest stable ohms I can go. Meaning if I get a new amp I have to make sure its most powerful at 2 ohms, rather then 1. I would get 2 subs, but one it will cost more and two it will take up most of my trunk. I like to keep room in my trunk for when I need it. As far as the box goes, if I where to get a fully loaded bl what would be a good setup. and if i get a fully loaded btl what would be a good setup. If im not fully powering the btl would a smaller box help? Like Since its only getting 2/3 what it can easily take would I use 2/3 the max box size. But then when I upgraded would that bring a problem. Also I read somewhere that you should tune the box to around 32 htz. Does that sound about right?
