Hey Guys, I plan on installing CDT Audio CL-61A components in the front doors and either CDT 6.5 or 5.25 2 way full range speakers or middbass drivers of the same size. Now my question is this. Just like how it's possible to place 6.5" or 5.25" speakers in the front doors by fabricating a bracket is the same possible for the rear door panel. I'd really prefer the 6.5" 'cause those things sound awesome. So what do you guys recommend?
Oh yeah the truck is a 1997 Ford F-150 ext Cab. I'm asking this because as far as I know CDT doesn't make 6x8/5x7 speakers

Thanks in advance

 

doubt it. 5.25 will fit, but the mounthing depth of CDTs are jus a bit too much.

 

inque is correct. The depth of the 6.5" is too deep for the rear door and unlike the front door you don't have room to fit a spacer behind the door panel on the rear doors of the ext cab. Now what you could do would be modify the rear door panels so that you could get them to fit but it would involve cutting the rear panel and I don't know how you feel about that. Anyway, yes it is possible to get them in there but modifications would be required.

 

I second that.


I have some db650 Polk's in the rear right now and the tweeter is holding the factory grill off the surrounds....


if you find a quick mod, let me know!

 

if your good with the saw, u could always cut the grills, attach a plastic adapter over the hole, the plastic prolly being about 1in+ thick, and let your speakers out of their original mounting hole. that should give ample room. dont forget to damper your plastic and panel tho, or else, you're gonna have major resonating due to flimsyness

 

I'll be doing just that in near future. That plastic grill is 3/8" thick at the MOST. I'm considering glassing in the rest of the panel in order to avoid resonance. BTW - I do not believe Polk advertised mounting depth's and/or their tweeter heights. Upon starting this project I will physically measure said speakers and post actual depths for those that are interested. I'm pretty happy with them as a whole. As soon as I can sneak some MB's up front, their only gonna be getting 50w each for (relatively loud) fill anyhow.

 

I've got a '99 f-150 extended cab that I put 6x9's in the front and rear doors. They are mounted behind the door opening instead of in front of it. you can't even tell I have aftermarket speakers. I can still put the stock 6x8's in if I need to. All I did was use the templete that came with the speakers and used a drimeltool to cutout the top portion and lower portion. I left the sides alone with the 6x8 mounting holes.

 

How shallow mount are those speakers!!?

 

Well what you could do to modify the rear panel is to cut the panel itself out where the grille portion is. Next get you a piece of 3/4" MDF and router out some nice grills (kinda like a home speaker has). Next take your custome grille ring and stretch some grille cloth over it and staple it from behind. Next use screws to secure the next grille over the hole you cut in the trim panel (from the inside of the door panel obvisouly with short screws so you will not see how it is mounted). This will give you roughly 3/4" more depth since you will now be able to use a spacer ring and bring the driver out of the door more. If you need additional depth just use two pieces of 3/4" stacked on top of each other and use a chamfer router bit to bevel the edges and make it look more stock. The stacking will now give you an extra 1 1/2" to use an even taller spacer ring. You get the idea I am sure. You could even go as far as glassing the door panel and building an enslosure and mounting subs in the rear doors if you so desired.

 

The 6x9 speakers I have are pioneer 4-ways. They have a bottom mount depth of 3 13/16". There is about 4" of room in the doors. It is a tight fit to get them in the doors, but once there in theirs plenty of room for them. They sound a lot better than the stock size and were worth the time to put them in.

 

Thanks for all the info guys. I think I'll just cut the grill and mount a midbass driver in there. I have enough highs in the front.
