To have it better explained, your saying that your too afraid to take our advice when your getting so ri[pped off.
That box is too small for the subs even sealed! sadness
We can hook you up with a smaller, much more realistic looking and fitting custom ported box for 175 plus shipping which wouldnt be over 100. Then you have 425 left over for subs. Want sq? sure many ppl know of 2 12s that will KILL the 15lzs in the prefab box.
or you can spend less on a little smaller box (less shipping too) and about 200 on 2 12s that will be just as loud/ sound better than that 15l7 sealed setup.
is this ext cab?
