Alright to start off i dont mind waiting for a little. So the question is what should i wait for . I have and ext cab s10, i believe if i do a half wall i will be able to put two of the spl 12's he has cooking in a ported box in the back. or i could go will two of his 15's in a ported box, or finally one IXL 18.4 in a very big and stuffed sealed box.. I would love a lot of output, i could deal with a little SQ but spl is my main concern, as well as lows i absolutly love my lows so what do you thank i should get. I dont know exactly how much i can fit back there but it should be around 7-9 cubes for the half wall.
