I made the mistake of reading that "going to 6.5" is an easy swap". That's the biggest crock of **** ever. I've done stereo builds in my last 4 cars, and this was by far the biggest pain to mount 6.5" in the door pods. I removed the pods entirely and just sealed off the hole. But due to the contours and bends it was not an easy process.

Most any 5.25" should fit in the door though.

 

Lots of options out there. I've used JL Audio C3 and C5 in 5 1/4 " in the door with good success. Focal, Hertz, Hybrid Audio are also considerations albeit pricey.

 

One more question.... Got all the speaker connections sorted out thanks to all your help. Now for the really stupid ones :-).

There three wires that don't yet have a home. A thin red/black; a thick red/black; and an orange one. On the head unit I have only Battery and Ignition access spots???

There is a Blue/White that I assume connects to the blue/white Power Cont.?

There is a Blue/Purple that has a tag "relay" hanging there too.

Any and all help is GREATLY appreciated!!

 

Got it all connected and it works. Still have to play a little with it but it 'seems' that following the schematics and running a common ground from the HU with all four channels (negative) leads to the single front left negtive lead to the amp somehow is blocking out the balance control between the speakers. I get all four channels playing but moving the fader left/right doesn't seem to be effective. Had thought about running each set of speakers wires in matching +/- sets going into the amp, but, the schematics show binding them in common.

 

I used Infinity Kappa 52.9. They fit quite easily. They are 5 1/4 though not 6".

 

You're not finished if the fade doesn't work... What head unit and amp are you using?
