I didn't know the 9-Speaker could sound this good...

[james cole]

Hello Guys,

So I have the 9-Speaker on a 22 Mach 1.

Did the following:
- Fully deadened the doors (they rattled with the slightest bass note)
- Removed Center Speaker
- Disabled Factory EQ using Forscan

I am an audio nut, but I am really impressed with this system now, the amount of bass that 6.5" produce is quite a lot, is it me or deleting the center channel produces more power and... bass??? What would happen if I delete the rear shelf speakers?

Power (to me) is more than enough and Imaging is quite excellent.

Only downside is the 3.5" Mid and Tweet are a bit muddy, that is a speaker issue and probably not the amp.

Have you guys changed this two speakers and what results did you get? Does the tweeter have a built in capacitor or is the signal crossed over at the amp? What ohms are these two speakers?

I am thinking that only changing this two speakers could really clean things up... really hesitant to swap the 6.5" since they produce a lot of bass.

Thanks!
JC

This is what I need to do. My passenger side door rattles something fierce with certain frequencies. For a $1000.00 add-on to my 2021 I'm a little disappointed that this is what happens from the factory.

Yes, I simply cannot enjoy music if all I hear are rattles...

Should probably be fixed for free. Doesn't happen at max boost/treble for me. On the flip side, its a small cabin and the pressure HAS to go somewhere.

So any insight if the mids and tweeters can be replaced with good results?

I would imagine it's not something Ford can fix. It probably needs Dynamat in the door or something.

I will have to try the EQ delete, I have done everything else you have done.

 

[gadgtfreek]

I'm going to do the EQ delete for sure.

Do you have any pictures of your dynamat in the doors? Where did you apply? I am getting ready to resume my dynamat project in the next month or so when weather cools a bit - doors are next - Just not totally sure how much I will do....

Rattles in the doors?? Could this be another symptom of pandemic specials?

In the 70s it was Coke bottles.

The tweeters certainly can and do produce great results, although they will need to be powered by a different amp. It’s a lot of work to pull it off though. I did tweets and the 6.5 mid bass speakers in mine and removed one rear deck speaker as port to allow bass to enter the cabin. I also unplugged the center speaker as well.

Does unplugging the center speaker have any affect on the sync/carplay/android voice prompts?

None…

So the OEM tweeter cannot be just replaced with the correct capacitor?

I planned to just replaced the mid and tweet…

I don’t know of anyone that has tried that. The mid and tweet change made a huge difference for me. In fact, my mids are running still on my factory amp and they sound great. I ran all new speaker wire for the tweets.
