ok.. so my car is tuned pretty low, 29 htz or so .. i peak some where around 38, the problem is .. while im at my computer, picking music that will sound good in my car is a crap shoot.. i have a powered 10'' sub now.. but its not tuned anywhere near as low as i need, so i have a shit load of 8's laying around... an old MTX 8 terminator single 4 .. 8 inch no name pretty stout single 4 and i have a pair of kicker comp 8's single 4s so i was thinking can i build a ported box or a horn or something to go under my desk .. tuned low so i can pick music that will sound great in my car. hope everything made sense
