Just replaced the front door speakers and added some Dynamat. Got everything from Crutchfield including the tool to pry off the panels. Suggestion, put some tape on the back of the pry tool to avoid any scratches.
Tweeters: Hertz C 26 OE
6.5": Memphis Audio MJP6
Tweeters were easy to install. The plastic cover pops off pretty easily. Added the bass blockers inline.
To replace the 6.5s first there are 2 screws on the door panel you need to remove. One is recessed under the armrest and the other is on the side under a small panel you pry open. Start at the bottom of the door where there is a recess to start prying off the panel. There are 3 electrical connections that you need to disconnect after the panel is loose.
The 6.5" is a little tricky. The original speakers have 3 screws, not 4, and are spaced wider than a 6.5" speaker. I created 3 plastic clamps using the adapter rings that were included in the install kit. Ran foam around the back edge of the speaker and clamped it down.
I didn't want to mess with adding an amp. The sound quality is excellent how. Crisp, clean, nice firm bass, and no distortion. The tweeter made a huge improvement in sound quality. I installed the 6.5s a few days later and was amazed at how much it also cleaned up the sound quality. The original speakers are very, very poor quality.
I used a sound level meter on my iPhone to compare the new front speakers to the still original back speakers. The average output is about 9-10db louder at the same volume level. The key spec I looked for was the speaker sensitivity as the higher the number the higher the sound level with the same input.
The Hertz tweeter sensitivity is - 1W at 1 meter = 92
The Memphis 6.5" sensitivity is - 1W at 1 meter = 100
Next, I'm going to replace the rears with 6.5" 2 ways. Not sure which ones yet.
