My car was taken apart this week to install my system. I feel your pain.

Have fun putting everything back! [img]/w3timages/icons/wink.gif[/img]

where does the 3rd speaker go? doesnt the Q series come with a tweeter, and 2 other speakers. dont know what they're called. larger one, and mid sized one. thats why i didnt put them in my car, but i really wanted to.
and a question: if you dont use dynamat, will it still take 4 hours and be laborious? or is it just stick it in and go.??? thanks . awesome writeup.

That's not correct. The Q's I used (QM 218.61 Q) come with 2 pairs of drivers (two for each side, not three). Two 6.5" mid range drivers, and two tweeters. Pretty much the same configuration as the stock drivers.

You could cut the time needed at least in half. The Dynamatting is quite easy, just a bit time consuming. It is well worth the extra effort and cost. Putting the inner door panel back on is a bit tough, but if you pay attention to the tips in my post, it is not that bad. Skipping the Dynamat, you could avoid removing the inner door panel. But it's still not completely a bolt up proposition. The Q's need different mounting holes drilled for the midrange drivers. You also need to widen the hole slightly, (I used my metric hammer.) Finally, you need to wire the crossover; the stock system runs seperate wires to the midrange driver and tweeter; you need to run one of these to the crossover, then new wires to the tweeter and midrange.

One point I should add, is that I used a hot glue gun to attach the crossover to the inside of the door panels. This is not a level surface, and it took a good amount of glue sticks to bridge the gaps.

 

Was dynamatting the extreme inner portion of the door worth it? Could you just get away with dynamatting the area directly surrounding the speaker?

Since replacing my speakers, I do have some rattles coming from inside the door. Probably the speaker mount vibrating against the door. I'm hesitant to mess with the window though.

 

Nice write-up and pictures man.......kudos.
I also have some rattles come from my passenger door right in the middle where the crossover is mounted for my Infinity Perfect 6.1's I think my crossover's plastic case is vibrating against the door panel.

Good job!

Dynamatting the inside of the outer door skins does make a noticable difference in road noise. Also, the bigger and more structually weak a surface is, the more the Dynamat can help. For example Dyanmatting the roof of a car does more than the floor, given similar area. All the ribs in the floor make it less prone to unwanted vibrations. So as flexible as the door skins are, Dynamatting these definately helped. I was torn on doing the black metal inner door panel....and decided it might make mounting the interior door panel difficult. So I passed on that...but others here have Dynamatted that.

From what I have heard from others here, the most likely cause of rattling inside the door is the wiring harness banging around. The solution here is to use soft foam backed with adhesive. Peal off the backing, and wrap it sticky side out around the wires in key locations.This cushions the wires, and keeps them from rattling. While the stock harness wires already have some of this stuff in a few points, you need to add some more, and also add it to the wires you have going to the crossover.

If you read the thread carefully you will see some sugestions on dealing with the window tracks. There is no worry about getting the window out of adjustment as there is on some cars, you simply need to unbolt the tracks. Reattaching them the first time you do this is definately a b**ch, but once you know the trick it's not too bad at all.

 

As you can see from the above thread, I mounted my crossovers to the back of the interior door panel, in the lower rear corner. The MB Quart crossovers are about as large as they come, and there was plenty of room. Maybe whatever you used to tack the crossovers in place came loose. I origanilly used silicone adhesive, and the crossovers came loose and started rattling around. I had to take the doors apart again, and I then used a pretty large quantity of hot glue, and never had this problem again.

 

i want to dynamat my car like you did, but my car is a lease. Do you think Infiniti will give any problems if they find out my car is dynamatted?

 

Do you really think they will pull the door panels off when you return the car at the end of your lease??? Not a chance. They will be more concerned with scratches on the painted bumpers.

 

Very nicely done RacerX.

 

Nice write up, and I love the MB Quart Q series speakers, the best sounding car speakers that I've heard. So I was told that you can't add aftermarket speakers to the bose system, because the speakers are individually amped, is that not correct? If so what do you have to do to add aftermarket speakers?

Thanks,

John

 

Totally false. There is no problem at all changing the speakers without changing the amp. Of course, you will not be able to appreciate the true capabilities of the MB Quarts, (or other good components) if you keep the stock amp. My MB's sounded great with the Bose amp. BUT, there was a huge improvement again when I switched to my JL 300/4 to power them.

 

RacerX,

Where did you put the JL amp? Also, what other speakers do have in your car?
