Question Best place to mount aftermarket crossover for front doors?

So I am in the middle of installing new component speakers for the front doors of my WK2 and I have never done this kind of install before. I want to mount the crossovers in the right place.

What have you guys done with your crossovers?

Re: Best place to mount aftermarket crossover for front doors?

Figured it out. In case anyone runs into this in the future, when switching to a 6.5 from the 6x9 a Scosche adapter plate moves the 6.5 off-center. I did some test fitting, and opted to mount the plate so it moves the speaker up, which made room to mount the crossover on the vertical support brace behind it. See attached image.

Ran a single screw to secure it. I just had to be careful to not interfere with the cable running vertically behind the brace. The velcro is just to eliminate noise, just in case. I will also run a zip tie through the slots to ensure the sucker doesn't move.

Re: Best place to mount aftermarket crossover for front doors?

So, I realize that I am replying to my own posts...which is odd...but hey...if it helps someone.

Anyway...I think I did all that work for nothing, because I was looking at things. There are two separate wires coming in...one for the mid speaker, and one for the tweeter.

Since I am only upgrading the speakers and not the factory head unit and amp, I shouldn't use the Polk crossover...that work is already done by the factory hardware.

And then I found this post, which I believe confirms this...

Doesn't seem to make sense to add another crossover - and I don't know how you could wire it. It don't think it would make sense to attach both the tweeter and woofer channels into the 'IN' terminals on the crossover, and then take the separate feeds from there.

Now if you completely rewire the system and have a summated single channel coming into the door, then certainly use the crossover and have it split the signal for your tweeter and woofer.
Ahhhh...live and learn...

Thanks for the info!

Do you have any vibrations or noise from the 6x9 to 6.5 adapter? I got pretty bad vibration using those adapters. Ended up ripping it all out and getting a 6x9 component set.

I dunno...haven't fully hooked it up yet. I spent all my time getting the crossover in the right place and decided I would need to finish it tomorrow.

If I knew then what I just figured out about how I should not using the Polk crossover...I would have spent the time more effectively.

I did place some Dynamat on the backside of the adapter plate. I don't know if it will help or not.
