Im visiting home for a while and my 1988 suburban is just sitting in the driveway. so i decided to to some audio shuffling. im gunna swap my after market head unit out of it and put it in my dodge. i also have a new set of MTX 3 1/2 inch speakers that i never got around to installing into the dash. and a set of 6x9 pioneers that were supposed to go into the back of the burb. My truck is a 2004 RC st. is there a slot for the MTX speaker in the dash? and is there anywhere where i can mount the 6x9 or are they just a lost cause? when i bought my truck from the used car dealership it came with 2x12 subs, tweeters in the headliner in the back corners and a 1400watt amp and a CAP.

 

Well depending on the model(i think) you should have speaker cut outs on your dash, if you do then the 3 1/2's will work, you will just need to run wires. As for the 6x9's thats the stock size that come in our doors....So you should be fine.

 

after i took the speakers out i found out that they are not 6x9 instead they are 4x10.... i haven't cracked into door panel yet. will they fit or am i screwed? also do you know where i can dig up a wiring diagram im gunna have to splice all the wires from the new head unit.

 

Well, a decent set of 6x9s isn't terribly expensive. You can get adapters to make the 4x10s fit, but that money will serve better spent on new speakers.

 

Oh i see you had speakers you bought for the burb which are a 4x10. The speakers in the door of your ram are a 6x9. You can find a decent set of 6x9's for under $100 bucks.

 

i would pick up some 3 way 6x9's off amazon for ebay (around $60 for a good set). they fit in the doors no problem, but I had to use the existing speakers mounting bracket to make it fit the hole and be deep enough. The brackets didnt fit my pioneer's so i cut off the tabs and ****'s and they worked great.

in the dash you should have empty 3 1/2 holes as mentioned above, unless you had premium sound, then there would be speakers there (and i think one in the middle)

in my std cab there are 5 1/4 in the rear, i wish i bought 6 1/2 components and made them fit but i bought 5 1/4 components and had to use a special bracket to get them to fit good. 6 1/2 might require enlarging the opening though.

 

You can fit a 6 1/2 without any modification, the biggest thing about our doors is they arent that deep, so you need to be aware of that and pick the speaker accordingly.

 

I got 6x9 in my rear doors...not mod free, but they are there.

 

He wasnt asking if he could put the supposed-"6x9's in the back of the Ram. That was for the 'burb.
No, 4x10's won't fit in the front doors as they are too long. most aftermarket 6x9's are a tight squeeze in the front doors and most need a spacer. My Polk audio's I used to have came with 3/8" spacers which were hardly enough to make them fit.

As for the dash, the 3.5's that go in there are a slim 3.5". You will likely need to cut some plastic to make them fit...not 100% sure as I don't have 3.5's in the dash. speakers bouncing off the windshield just sound terrible and ruin the sound stage. Most like the sound, but only because they are oblivious to what a stereo should sound like. I mean it is a truck after all, but I'm an audio freak..haha
Rear doors are 5.25" for older years and 6.5" for 06+ years.
You can visit the Audio Section for what sounds best kinda thing.
