Installing 4x9 Speakers In The Rear

[TheTrueMoron]

The rear door speakers of my '01 extended cab aren't exactly 4x6" but that's the size that Crutchfield says to install. I've heard that some people have managed to rig up ways to put in 6x9" speakers. Should I try to install 6x9"s or should I just go with 4x6"s? If anyone knows how to get 6x9" speakers in the rear doors, please let me know. Thanks.

I don't know about 6 x 9's...But I've known a couple of people mount 6" or 8" diameter mid-bass drivers in there. There's plenty of room, you just have to be very not-shy about trimming sheetmetal.

 

My issue with why I didn't do this in my '02 Ex cab not because I was afraid to cut the metal, but because I didn't want to modify the door panel...The grill on there is set up for a 4x6 speaker in there. If you put a bigger one back there, you'd need to cut a lot of the door panel off in order to actually get the sound out of them.

 

So I stuck some 4x6 Infinity plates in there, threw 125 watts RMS at each of them, and called it good.

 

But looking at the inside of the door, since there's no window mechanism or anything holding you back and lots of room in there...Heck, you could probably mount a 10" shallow-mount subwoofer in each door if you were feeling like Captain McFabricator that day.

I was able to get a 5.25" Mid-Bass Woofer in the rear of a 01 Silverado Extended Cab without trimming any sheet meet. I did have to close-up a small space since the opening was oval rather than round. You need a shallow mount speaker because you have approx 3" before you hit sheet metal again.

 

If your looking for more bass than your factory 4x6 speakers, while retaining that factory look - Take a peek at Audiobahn AMD50Q (5-1/4" Midbass Drivers) Frequency Response: 35Hz - 5kHz, 30 oz. Strontium Magnet, Sensitivity: 92dB, and Mounting Depth: 2 1/2". I would recommend using an amp that had low pass filter make these drivers pound.

I too put a 5.25" instead of the 4x6. You do have to trim some sheetmetal, but the diameter of the 5.25 just centers with the door panels' perforated grille so that panel didn't have to be modified. The side openings left by the 4x6 opening on either side of the 5.25 cutout, I covered over with Dynamat. I layed an 8x10 sheet over the opening and just cut the "footprint" of the 5.25 mounting.
