The F-150 SuperCab gives you more room for family, pets, stuff--and audio upgrades. The comfortable interior offers plenty of space for a new receiver, speakers, and even a subwoofer. You'll have plenty of great products to choose from, and the modular design takes the hassle out of installation.

Factory System

The 2004-2008 F-150 SuperCab came with several receiver options. An AM/FM/CD receiver came standard, but Ford offered three other choices:

  • an AM/FM/6-disc in-dash changer;
  • AM/FM stereo/6-disc CD changer with Audiophile Sound System with MP3 (with factory sub);
  • Rear seat DVD Entertainment System

Note: You will lose the use of the Rear seat DVD system if you replace the factory radio.

Tools Needed:

  • To install a new stereo, you'll need a 7mm socket wrench and a panel tool.
  • To replace the speakers, you'll need a panel tool, along with 5.5mm, 8mm, 10mm, 1/4", and 7/32" sockets.
  • To access the rear subwoofer location, you'll need a 10mm socket and a Torx T20 driver.
Factory Radio

Replacing the factory radio

There's plenty of room behind the dash, so you can install just about any car stereo in this truck, including single-DIN (2" tall) and double-DIN (4" tall) receivers. You'll need a mounting kit to trim out the new radio, along with a wiring harness that allows you to connect your new radio without having to cut the factory wiring. Crutchfield includes these installation parts at a very nice discount with most orders, along with our free MasterSheet™ step-by-step instructions for your F-150.

You'll have no problem fitting accessory items like satellite radio tuners, iPod® adapters, navigation modules, or even small amps back behind your new stereo. Remove a couple of trim pieces, and you'll have all the access you need for the installation. You'll lose the factory Video Entertainment feature if you replace the Ford radio.

Steering wheel audio controls

Two companies (PAC and Axxess) make adapters that allow you to connect your Ford steering wheel audio controls to a new car stereo. The F-150 uses a single wire to send commands to the factory radio, so you can install either adapter without much trouble.

Replacing the factory speakers

This truck will accept several speaker sizes: 6"x8" speakers drop right in, most 5"x7"s will also fit, and 5-1/4" speakers will fit in with mounting brackets. You'll find enough room in both locations that you can almost always buy matching speakers for front and back.

It's a good idea to get speaker harnesses for your new speakers. They'll allow you to attach the new speakers to the plugs that connect to the Ford factory speakers, and they make it easier to reinstall the factory speakers if you ever sell your truck The brackets and speaker wiring harnesses can be purchased at a deep discount with every speaker order.

Front doors 

You don't have to pry off the entire door panel; there's a pop-out panel that covers the speaker location. Since the SuperCab offered advanced audio options, you should find factory tweeter openings in the front door panels in addition to the oval 6"x8" openings. If you're handy with tools, you can fashion a plate to hold aftermarket tweeters in those openings. Since the speaker openings are high up in the front doors, you'll get great sound from a nice set of component speakers. You can also install kick panel enclosures that hold 6-1/2" speakers and tweeters in this truck if you prefer that option.

Rear doors 

You will have to remove the rear door panels to access the speakers. Again, there's plenty of room for most 6"x8" speakers, or you can also use 5-1/4" speakers in brackets.

Bass in your F-150

Adding some extra thump to your F-150 isn't hard, but the amount of effort involved depends on how your truck was equipped when it rolled out of the factory.

With factory sub

This Ford truck offered a factory sub as an option. If you have the factory enclosure under the rear seat, you can replace the 8" DVC sub with any aftermarket sub that has a mounting depth less than 3.6 inches. If you pick a high-performance sub, you'll want to replace the factory amp too.

The factory stereo only sends 5 volts to the sub amp, which can cause a turn on/off pop from the subwoofer when an aftermarket stereo is installed. To avoid this, a 12V-to-5V regulator can be installed on the remote lead. This regulator produces a large amount of heat for its size and should be bolted or screwed to a clean metal surface that will act as a heat sink.

Without factory sub

If you don't have the Ford factory sub (or if you want to replace yours), you'll find a bunch of subwoofer options available. Your best bet would be vehicle-specific enclosures from 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. There's also room under the rear seat for a compact Class D amp that will deliver some serious bass power.

Other options

With a vehicle like the F-150 SuperCab, there are lots of ways to upgrade your entertainment and security.

iPod® and video

iPod users, you'll find a great spot for an iPod connection next to the 12-volt port that's situated low in your console, and the pocket just below that port is a great place to stash your player. Also, if you're thinking about installing an overhead video screen, the JCI rail system in your headliner contains power and ground leads that you can tap into, making that job much, much easier.

Floor mats

No matter how much you pamper your truck, you're eventually going to get involved in some sort of truck-like activity that gets you and/or it dirty. When that happens, it's a good idea to have a set of WeatherTech Floor Mats in your truck. These incredibly durable mats trap moisture, contain dirt, and keep your factory carpets looking good.

Security and remote start

If you have thought about adding security or remote start to your F-150, you'll have ample room to mount the security system of your choice, and all models that we carry would be a great fit for this truck. All the connections you'll need to make are in convenient locations, and you won't have to break your back in the process. If you have heated seats and you plan to add remote start, we can help you turn these on when you start your truck remotely. When you come out to your F-150 on a cold winter day, the seats will be nice and warm.

You'll need a few extra parts to install your security system in the F-150. Four diodes will be needed for door trigger isolation on your SuperCab truck. You'll also need one E5000 relay if you plan on having the dome light supervision option — this feature turns on the dome light for 30 seconds upon disarming the system. If you are adding a system that has the remote start option, you will need a module to bypass factory transponder system. We suggest the FLCAN interface. Flashlogic has done extensive testing on the Ford platform, and they have developed a bulletproof algorithm for bypassing the Ford P.A.T.S. transponder system. We also carry the XK05 by Xpresskit that will perform the same bypass as well.
