ok, this is gonna sound dumb but, i dont want a speaker in the door (mid and high) and only have one workin...when i have my system up its kinda like a quick check for me to see if my amp is workin right (ive fried my last amp) which messed up one of my speakers, so if i look over and see my mid movin then it seems like things are workin right....dont necessarily want the bass in the door, nor need it, but its nice to have it there
