Passive crossover

[grahamc]

Hi,

Quick question about passive crossovers. I am looking at buying some JBL mids and tweeters, with passive crossovers, for the front doors.

My question is:

If the mid and tweeters are in the front doors, where should the crossover be? Can it be where the rear seats are (this is where my amps are going to be)? Or should they be as close to the mids and tweeters as possible?

Thanks,
Graham

The crossovers can go anywhere you like. The only down-side to mounting them away from the speakers is that you double the amount of speaker wire you'll need to use.
If your speakers and tweeters are mounted in the doors and you want to mount the crossover in the car, remember you'll need to run another speaker cable into the door. (2 pairs in total).

Thats great! Thanks for that. I have the speak cabling already and have more than enough.

Great to know! Much appreciate it!

steady on with that thought............. :)

I've just put a set of JBL components in the front doors and getting the new speaker cable through the rubber grommet thingy between the car body and the door was a pain in the ar$e. So trying to get two cables through could be a pain.

I used the template on here to make the new speaker brackets and mounted the crossover on the rear of the speaker bracket. it's out of the way there and you only need to run the single speaker cable through.......

just my thoughts,

cheers

If you've mounted that on the inner side of the door, I'd suggest moving it before it rains too much. The inner side of a door is known as the 'wet' side. The plastic membrain is there to serarate the two sides. Don't just wrap it up in something either as that will probably get condensation in it and you'll end up with the same problem. It won't be long before it stops working.

Mounting it on the 'dry' side of the door is fine though, so you won't need to re-run any speaker cables :)

Thanks for this, I will give it look see tonight, as my door cards are off the car, carpet is up and I need to lay the wires this weekend.

How big are the crossovers? are they nice and pretty?

You could possibly build them in the base of the glovebox with say a neon and some plexiglass...

Otherwise I would try and mount them near the front to save on cable as the other guys have said...

They are usually small enough to be placed alongside the speaker drivers themselves... and this is the best place. Make sure they are secured down so you don't get vibrations and rattles..

As far as cabling, I have plenty.... so not concerned there.

The idea is that the 2 crossovers are going to be fitting nice and neatly as part of the install in the boot, underneath the AMP that is driving it.

I had this problem in a previous car, and is one of the main reasons that I want to install them with the AMP, at the back, in place of the rear seat.

Oh,
I should have said, it's all on the dry side. I made sure the membraine was not damaged and secured back in place after.

It's probably worth pointing out that the MDF will not like moisture either so be carful here.
