the list can go on and on.

i listen mainly to MP3s off my ipod and jump drive on a Pioneer AVH-P4000DVD deck

music type is more often rock, but some rap and what not.

im not worried at this time about the back fill speakers, or the a sub.

the vehicle is a 03 Hummer H2.

any help is greatly appreciated.

thank you
