Dodge Ram Quad Cab

With an oversized grille and styling that really says "Made in the U.S.A," the Dodge Ram 1500 Quad Cab  is one of the most distinctive vehicles on the road today. The 2002-05 version is a particularly cool-looking vehicle, so we talk to lots of Ram owners who want to upgrade their factory audio systems because they plan on hanging on to their trucks.

Most 2002-05 Dodge Ram 1500 Quad Cab trucks came with an Infinity system with seven speakers in the dash and doors. You have a range of options for upgrading the audio system in this truck, so it can be a little confusing. But the good news is that you also have lots of choices for replacing your receiver and speakers, and you'll find a bunch of sub enclosures made specifically for this truck.

Replacing your factory radio

The Ram's factory radios are reasonably easy to remove and replace.

4-speaker system

In 2002 and 2003, all Quad Cabs came with the Infinity system, but Dodge offered the basic 4-speaker system beginning in 2004. You'll have to remove a section of the dash in order to pull out the factory radio, but it's not a difficult job.  You'll need a mounting kit to trim out the new radio, a wiring harness that allows you to connect your new radio without having to cut the factory wiring, and an antenna adapter that connects the Dodge antenna wire to your new stereo. The kit, harness, and antennna adapter are available at a steep discount with most Crutchfield stereo orders, plus you'll get our illustrated, step-by-step Crutchfield MasterSheet™ free with your purchase.

Infinity system

The Infinity system includes a CD/cassette receiver or a CD receiver in the dash, and a complement of 7 speakers: 3-1/2" speakers in the dash (left, right), a 2-1/2" center dash speaker, two 6"x9" woofers in the front doors, and two 5-1/4" speakers in the rear doors. You'll have to remove a section of the dash to install a new stereo, as you do with the non-Infinity system.

You'll need a special adapter to connect a new stereo to the Infinity factory amp. Your new stereo must have front and rear preamp outputs to work with this special adapter, and you'll lose your fader control if your truck is equipped with the UConnect Hands-Free System. This adapter is also available at a deep discount when purchased with a receiver.

The mounting kit for this truck holds any DIN (2" tall) radio in the dash opening. You have to remove the entire receiver/climate control trim panel to access the stereo, but that's not too tough. Here's what the kit looks like installed.

Here are a few things to keep in mind when you consider a new car stereo:

  • If you have factory Sirius Satellite Radio, you'll lose this capability if you replace the factory radio.
  • If your vehicle is equipped with a factory hands-free cell phone interface, you'll lose this capability if you replace the factory radio.
  • Have factory navigation? You'll lose it when you replace your radio.
  • Video receivers with flip-out monitors aren't a good idea in this vehicle because of the way the dash is shaped.

If you like the sound of the factory system, but it's just not loud enough for you, you might consider JL Audio's Clean Sweep or some other factory sound processor. This type of processor allows you to tie an amp (and even speakers) into your factory radio, for a big boost in performance.

Tools needed: Phillips screwdriver, flat blade screwdriver, panel tool.

Steering wheel audio controls

It's relatively easy to retain your Dodge Ram's steering wheel audio controls when you install a new stereo. When you enter your vehicle information, our database will choose the adapter you need to make your factory steering wheel audio controls work with your new receiver.

Replacing your factory speakers

Depending on the model, your Dodge Ram will have factory speakers in the front doors, the dash, and the rear doors.

4-speaker system

You have 6"x9"s in the front doors, but your choices are limited by space considerations. You can also put 5-1/4" or 6-1/2" speakers in the front doors with the help of mounting brackets. You can put 6-1/2" speakers in the rear doors, but you'll have to drill new screw holes. Speaker harnesses are available for both locations. They'll allow you to attach the new speakers to the plugs that connect to the Dodge factory speakers, and they make it easier to reinstall the factory speakers if you ever sell your truck.  (Crutchfield includes these speaker wiring harnesses free with every speaker order).

Infinity 7-speaker system

You have a factory amp behind the glove box that powers the three dash speakers, the front door 6"x9" subs, and the full-range rear speakers. If you're planning on upgrading your speakers, you have some choices to make.

  • If you're keeping your factory radio, you can replace all your speakers, but keep in mind that the front door speakers are just producing bass.
  • If you're replacing the factory radio, you can connect your new stereo to the factory Infinity amp — you should get a little boost in performance but the speakers will continue to work as they do now. You can replace most of your speakers, but again, the front door speakers will only produce bass.
  • You'll get the best results if you bypass the Infinity amp. Just run speaker wire from the new stereo to the glove box, then tie into the speaker wires coming off the factory amp. Then you have the option of running full-range 6"x9" speakers in your front doors, hooking up outboard amps, and building a full-blown audio system.

Dash speakers

You'll have to pry out the panel that runs all the way across the dash to access these speakers. You can replace the right and left dash speakers, but you'll have to splice the wires coming from your new speakers into the factory speaker wires. You'll have a hard time replacing the 2-1/2" center speaker, but you might as well leave it hooked up if you're keeping the factory amp.

You can splice or solder your new speaker's wires to the factory wiring, or use a set of Posi-Products connectors. We recommend the latter option, because it's faster, easier, and the connection is much stronger.

Tools needed: right-angle Phillips screwdriver, panel tool.

Front door speakers

You have to remove the entire door panel to access the front door speakers. If you're keeping the factory amp, go for the most efficient 2-way 6"x9"s you can find. If you're replacing the whole system and installing a subwoofer, then you should consider putting a round speaker (5-1/4" or 6-1/2") in the door for better accuracy. Here's a cool idea: if you're replacing the whole system but you don't want a sub, consider putting 6-1/2" or 6"x9" subs in the doors and powering them with an amp.

Rear door speakers

You have to remove the entire door panel to access the rear door speakers. The 5-1/4" factory speaker is kind of an odd size. You can install a 6-1/2" speaker easily in this opening but you will have to drill new screw holes, so make sure you have the tools for that!

Tools needed: Phillips screwdriver, panel tool, T30 Torx driver.

Bass in your Ram truck

You'll find an impressive selection of enclosures made for this Dodge Ram Quad Cab by manufacturers like JL Audio, Q-Logic, or MTX, available in unloaded, loaded, and amplified versions. They'll give you powerful bass without wasting much (if any) space.

Other options

There are plenty of other ways to improve the sound and functionality of your Dodge Ram Quad Cab. Here are some of the ways Crutchfield can help.

Rear-view camera

With a vehicle this large, it's important to be aware of your surroundings. A rear-view camera is a big help when you're backing up in a crowded parking lot.

Speaker baffles

We frequently suggest speaker baffles for other vehicles, but for full-size trucks like this Dodge, we strongly recommend them. These thick doors can waste a lot of great sound, and this is an inexpensive way to rein it back in. The rubber baffles are easy to install, and they'll give you better performance while also protecting your speakers.


Installing a security system in your Dodge pickup isn't easy (security systems rarely are), but it's definitely a good idea. Our Crutchfield Advisors can help figure out what you need to get the job done, but we usually recommend taking your car and new gear to a professional installer.

    Hi, I have a 2003 Dodge 1500 with the stock stereo/head unit in it. I was wondering if it is possible to connect my ipod to it somehow through an adapter or something along those lines. Any help would be greatly appreciated!! Thank you, Shawn

    Shawn, That's totally possible, actually. I've forwarded your question to our sales team, and they'll be contacting you via email soon. For immediate help, you can contact them via phone or chat.

    Briley, If you want to enjoy your iPod in your pickup, you can use an iPod adapter with the factory radio, or replace the stock radio with an iPod-friendly aftermarket receiver. I'll forward this to our sales team, and they'll be contacting you via email soon. For immediate help, you can contact them via phone or chat.

    I've got the infinity system's in my 2002 Ram, what will be the impedance for the front door and left/right dash speakers?

  • Jon Paulette from Crutchfield

    Posted on 10/22/2015 10:57:53 AM

    Serge, This could vary from one factory system to another. The best way to tell is to examine the speakers themselves. If you'd like some help finding the best replacements, give us a call!

    I have a 2004 Dodge 1500 with the Hemi 5.7 engine. For weeks the radio was updating and stayed at 60%, then it asked for the navigation cd. It was stuck in this stage, and has a music cd in it and will not allow me to change modes or eject the music cd. It will, in a day or two run my battery done. How can I stop this update and resume normal play? I already disconnected the battery that worked only temporarily.

    Bob, Assuming that you're talking about the factory stereo, you probably need to see your local Dodge/Ram dealer. If the factory receiver is beyond help, we can help you find an aftermarket model that will fit your truck. Good luck!

    I'd like to know if Dodge had OEM steering wheels with factory radio controls in 2004. I have an '04 that only has cruise control on the steering wheel but I'd like to add radio control.

  • Jon Paulette from Crutchfield

    Posted on 11/2/2015 9:59:18 AM

    Justin. Steering wheel audio control was an option on Dodge Rams in 2004. As far as the actual swap goes, you might want to check out a Ram owners' forum to see if anyone's done it before. Good luck!

    After removing the interior front door panel in my 2002 Dodge Ram Quad Cab 1500 SLT, I carefully measured the speaker opening before trying to installing speaker baffles for new speakers. When the window is rolled down, the gear that drives the window moves towards the speaker vicinity and interferes with the space needed for a speaker baffle. I first tried a 4 1/2 inch deep baffle and then looked into a 3 1/2 inch deep baffle. Also a 4 1/2 inch baffle will contact the window when the window is rolled down. A 3 1/2 inch baffle may contact the window but will make contact with the window gear. As far as I can tell a baffle cannot be used without some "modifications". This should be an easy installation. Is there something I am not understanding about the use of baffles for my Dodge??

  • Jon Paulette from Crutchfield

    Posted on 11/17/2015 9:54:59 AM

    James, You're spot-on, actually. We modify baffles all the time. Cutting the back off will help with your depth issues, and you'll still have the rest of the baffle to protect the speaker from moisture.

    I was looking at purchasing the Alpine 6.1" Bluetooth Receiver with Android/iPhone/iPod Control, USB & Aux (INE-W944) for my 05 ram 1500, are there corresponding dash kits that would work for me because it is a double din dedk, and will I lose cruise control option. I also have the mtx thunderstorms in the photo above with a clarion amp, would I need an amp wiring kit or would the wires I have now be OK to use.

    Hi I have a 2004 dodge ram 1500 with the infinity sound system and had to replace the front door speakers because they were blown when bought the truck. I replaced them with Kicker 6x9s that have the tweeter included also. They dont have the bass that the factory speakers have. is this because of the tweeters or something else? I also have a input wire for my ipod or phone on the factory system. When I play music off my phone it is almost normal but the volume is a little bit lower, and when i play pandora it is only half the volume. Can you tell me why this might be?

  • Jon Paulette from Crutchfield

    John, The Infinity front door speakers were actually 6" x 9" subwoofers. To get total performance from a set of full-range speakers, you'll need to install a new receiver and bypass the factory amp. As for the playback issue, that's a toughie. But I'm guessing a new receiver would probably help there, too.

  • Jon Paulette from Crutchfield

    Posted on 11/23/2015 10:21:56 AM

    Ryan, A double-DIN receiver can fit, but you'll need to modify your dash to make it work. I'll forward your questions to our sales team and they'll be contacting you via email soon. For immediate help, you can contact them via phone or chat.
