I've got a 2001 Mitsubishi Montero Sport with the standard non-Infinity CD player and speakers. The speaker in the right rear door has just developed an annoying distortion, I guess it's blown. According to Crutchfield, this is a 6.5-6.75" speaker. Recommendations, please on a decent pair of replacement speakers for under $100. I have seen online Kenwoods, Clarion, Blauplunkt that are coaxial and will fit, any to avoid? Also, any special tools needed to get the door panel off?
