The Exile that I installed in that Land Cruser was a big let down..The Clarion out did that sub no problem..
I have no idea about the pioneer or Earthquak..
I hear you on eD its kinda hit & miss..
The JL Slim will be very nice.. We had the JL rep take us out the other day..
I took a look at some of the new stuff it was much better than I would have thought before.. Iv never been a big JL fan but They are creeping up my list..
Another thing you could try is some RE8's or somthing like that..
I installed 2 in my Ladies car and they wang like no other.. love the lil guys.. Im doing a Custom Box for (1) RE8 we shall see..
peace Troy
