Long glass packs or cherry bombs should do the trick. Also, if you want real deep put some mega phone tips on it. the longer the deaper the tone. I had a truck @ 1 time that i did all that & it had a real deep tone, almost deaper than most sub woffers. The tips were 3 1/2'' in dia & 24" long with a slant cut on one end. I don't know who makes them but advanced auto can speacial order them & they come in 3 or 4 different length
