So I've got an 02 Xlt, I've been looking into a full upgrade on my Audio system, new speakers, HU, a sub, and was actually thinking of installing 2 new speakers. The 2 new speakers would go into the cargo door. Has anyone here dont this? And how difficult is this? I've done alot of sound system installs but nothing like that. So if anyone has some input or advice please let me know. Thanx. Jimmylinx
