anyone interested in replacing door speakers but....
 

Any comments on the Polk DB 6501s as a component set? I have seen on here a few others use them with what seems like good results?

Until I save a little more money I am thinking about just upgrading the components myself....

However, thinking about it a little more it sounds as though I will need to switch all the wiring as I will be running crossovers with whatever component setup I run. I assume this will require a new harness etc....I was thinking about as someone said.....buying everything I want/need and having a local shop install it....I have done that to a certain degree before with my civic with good success.

I am looking for a nice double din touch head unit.....no navigation...

Here is one I was thinking about....
Pioneer AVHX4600BT 7-Inch USB Bluetooth Hi-Volt Pandora DVD Player https://www.amazon.com/dp/B00GN5K63M..._yiMwwbYBTYTBF

Any thoughts?

A harness to connect the new head unit to the OEM harness is a good idea. They are cheap and makes installation easier. They also give a diagram for you to follow so you know which wire is the "remote" wire. As for new speaker wire, buy a roll of 12g or even 14 g wire. They will all be coming from. The amp and routed to the door speaker. The romex opens with a simple flip of the locking mechanism. You have to close the door a little to get the locking mechanism to open all the way. Use a sharp utility knife to cut the pin board for space to run the wire through.

Okay. I bought both speakers and spacers. I was planning to do this myself thinking its plug and play. Took door panels out and I think it is going to be more involved. First, the spacer is a bit tight, maybe I need to make the inner diameter a little bigger so it will fit snugly in the speaker. I also think I need to do more modification so I can secure the new speaker in the OEM mount.

Anyone has pictures of their install of this speakers? Any help or guide would really be appreciated.

Pulled the trigger on these!

Questions:

Do I need any extra clips for the speaker terminals or can I use whatever the factory provided?

Dynamat: good idea/bad idea, and if so, how much/what kind for just the doors?

Do I need anything like foam parts, stuff like this:

Are there any stupid fragile nissan factory clips that I'll need special tools for to avoid breaking?

Are these the updated version? or better?

Not an updated version, just a different model entirely. I can't say better or not, I have no experience with them.

Just pulled the trigger on these!

and those Memphis audio 2.75" for the dash.

We'll see how good/bad this is with the STOCK headunit! This is the first time I've actually attempted not doing a separate amp just because I'm curious what cheap speakers with a lot of sound deadening can do first.

If you think this car has road noise, go drive an 02-07 wrx with an exhaust = tin can on wheels!

No idea, but they are not the same; These are a genuine co-axial, whereas the OP are simply midrange woofers. Could be better/worse if you have tweets in the doors AND the dash at the same time, I've heard arguments that messes up the soundstage, but I could be wrong and I've been out of this game for a long time!

After trying out the lanzars, I will say: if you don't have an amp, don't bother. Actually sounded worse than stock sadly. They look cool though! I may just have a bad head unit as it's always crackled in the right channel from new...

I'll go for a full set of Hertz and a nice JL audio 3 channel at this point... after I can tackle this seemingly impossible road noise issue. I'm still lost on how people on here just "live with" the road noise... maybe I'm getting old, but I just have higher expectations at this point. Just playing music louder isn't an option anymore.

Why even bother with a sound system when you actually need to move on and replace your car to let someone else enjoy the Z. Buy a Lexus or a battery operated car.

:iagree:

I love the car they can bury me in it! I just want a bit less road noise during those 2+ hour long trips where I often hit some bad sections of pavement. I'd rather hear the exhaust / music than the road noise drone!!

That's why you should have upgraded the head unit first. When I replaced my stock head unit with the Pioneer, it made the stock speakers sound a hell of a lot better. It would also make those new speakers of yours sound a lot better.
