Ill add my opinion when I get my 18" Q in for my friend. It will be 4 cubes tuned to 30 in a ext. cab S-10 on probably about 1500 watts. I got 2400 on tap.
haha i know i was originally gunna go with 8 cubes tuned to 28 facing up where those back seats are but my dad still wants to use it as a work car so he wouldnt let me
ok now theres a knocking sound when i play songs like bass i love you. Its pretty loud and distinct when it reaches high excursion. It could be hitting the seat or bottoming out but im not sure
