hey guys im going to be putting in alpine type R speakers in my doors and i was wondering if i should get the dynamat door speaker kit? the speakers will be amp'd. has anyone used it befor or it is just a waste of money?

 

Yes, you need it to help with sound, rattles and vibrations.
would never consider going without it!

 

^ what he said.

 

except not just the speaker kit, thats like 2 small squares. you need to dynamat the door

 

so the entire door will have to be dynamated? i am not going to car show loud but just a nice system kinda loud

 

dynamat (there are other brands out there at better prices) is just to get rid of the rattles and buzzing in the car. Z's are horrible from the factory with all sorts of annoying noises

 

If you have any opportunity to lay down sound deadening, do it.

When I swapped out of my speakers, I made sure to have sound deadening to apply while the door panels were off.

 

Door panels come off in a matter of minutes. Try it without. If you hear rattles or just feel like trying, buy dynamat and apply later.

 

I have Focal 165 V Slim component speakers in the stock door mount (tweeters mounted in the A-Pillars). Initially I mounted the speakers and didn’t install any sound deadening in the door. Then I added sound deadening (lining the entire door).

Truthfully I didn’t notice much difference in the speakers’ performance with or without sound deadening. Adding the sound deadening did provide a slight improvement, but I think the main advantage of using sound deadening was lowering noise from outside the door (the car itself). Please be advised that I was mounting the speakers in the OEM position.

The most advantageous place to add sound deadening in a Z (my experience is with the coupe) is in the rear floor/cargo area, around the rear wheel-wells, and the structure behind the seats. And, that’s mostly to kill the awful road noise you get with a coupe (that is really a mini station wagon with the rear wheels inside the car).
