2006-2012 Mitsubishi Eclipse

How to upgrade the stereo system in your Eclipse

Mitsubishi Eclipse coupe

In brief: This Crutchfield Research Garage article gives you an overview of your Mitsubishi's stock stereo system and your aftermarket upgrade options. We'll tell you all about:

Then, use our vehicle selector to find the gear that will fit your Eclipse.

Overview of the Mitsubishi Eclipse

The original Mitsubishi Eclipse was a rowdy little pocket rocket that captured the imagination of teenagers and tuners alike. The fourth (and final) generation Eclipse, on the other hand, is a more mature sort of sports car.

It's still plenty of fun, mind you — the optional V6 actually makes it the fastest Eclipse ever — but it's not the screaming, hair-on-fire thrill ride of yore. That's a good thing, since most people who remember the original car are trying desperately to hold on to the hair they (we) have left.

Of course, if you have the hair to spare, you can add some aftermarket performance parts and make your Eclipse as fast and furious as you like. The same goes for car audio. If you're looking for more power and punch from your stereo system, Crutchfield has the gear you need to make your Eclipse sound awesome.

Mitsubishi Eclipse Spyder

The factory stereo system

The Eclipse was available with two factory stereo systems. The base model was a 6-speaker AM/FM/CD/MP3 set-up, but the best option for audiophiles was optional Rockford Fosgate system. This premium stereo consisted of an AM/FM 6-disc in-dash receiver and 9 speakers (More like 7, since Mitsubishi treats the rear dual-voice coil speakers as seperates), including a subwoofer.

Though it's easily eclipsed (sorry, couldn't resist…) by just about any current aftermarket system, the Rockford Fosgate earned kudos from the automotive press when new, and it's really not bad now.

Some models are equipped with a satellite radio tuner, auxiliary audio jack, and steering wheel controls. An iPod® adapter was available as a dealer-installed option.

Removing the factory radio

Whether you have the base system or the Rockford Fosgate stereo, the radio removal process is pretty straightforward with the Eclipse. You'll start by gently prying out the edges of the receiver trim panel to release the retaining clips. We recommend that you use a panel tool for this type of work because screwdrivers can really damage plastic trim pieces.

Once everything's loose, pull out the trim panel, disconnect the wiring harnesses, and stash the panel in a safe place while you work on everything else. Remove the four Phillips screws that secure the factory radio, then pull it out and set it aside. Be sure to keep those screws handy, because you'll need them again later.

On first glance (and second, and third), it's hard to see how a new receiver could possibly work in the Eclipse. The factory receiver is so smoothly integrated into the trim panel that there's no room for even a single-DIN (2" tall) replacement, much less a double-DIN (4" tall) model.

Thankfully, there's a replacement trim panel that lets you install either size. It's available at a deep discount with your Crutchfield receiver purchase, and the finish matches up quite nicely with the dashboard. Depending on what's being installed, wiring harnesses or integration adapters are also available with your purchase, so you'll have what you need when you start the installation.

Installing your new receiver is just about as uncomplicated as removing the old one. Secure the new receiver to the mounting bracket following the instructions included with the installation kit, then connect the receiver wiring harness adapter to the receiver. Hold the receiver assembly near the dash, connect the receiver wiring adapter to the factory harness, and plug antenna lead into rear of receiver. From there's all you need to do is slide the assembly into the dash and secure everything in place with the screws you removed earlier.

Detailed stereo and speaker removal instructions

MasterSheet image
With step-by-step disassembly instructions and plenty of up-close, detailed photos, our exclusive Crutchfield MasterSheet™ takes the guesswork out of removing the factory stereo and speakers. It's free with your Crutchfield order, or you can purchase one separately for just $9.99.

Note: If your Eclipse is equipped with the Rockford Fosgate system, the dash tweeters and rear side panel speakers are powered directly by the receiver, while the door woofers and the subwoofer are powered by an amp located behind the right kick panel. If you're keeping the factory amp and want to retain fader control, the new receiver must have two pairs of RCA preamp outputs.

Tools needed: Phillips screwdriver, panel tool

Read our Car Stereo Buying Guide for shopping tips and advice.

Steering wheel audio controls

In most cases, it's reasonably easy to retain your car'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 controls work with a compatible aftermarket receiver.

Removing the factory speakers

The Eclipse has factory speakers in the dash, doors, and rear side panels. We'll take a look at both the Coupe and the Spyder versions below.

The dash speakers are easy to remove, but replacing them takes some work (Crutchfield Research Photo)

Dash speakers

The factory 4-ohm tweeters are located in the dash, near the base of the A-pillars. They're very easy to get to, but replacing them will involve a fair amount of work.

Mounting brackets are not available, so you'll need to drill new mounting holes, which, due to the angle of approach, is not at all easy in this location. Truth be told, this is the kind of job that's best left to professional installers unless you're very, very "good with tools". You can use a set of our universal backstraps to create brackets to hold the new tweeters in place. A wiring harness isn't available either, so you'll need to use Posi-Products connectors to connect the speaker wires to the vehicle's wiring system.

Wiring instructions can be found in your Crutchfield MasterSheet, and you can also check out our instructional video about wiring, which has plenty of information about splicing, soldering, and using Posi-Products connectors.

Tools needed: Panel tool

Front speakers

Regardless of the factory system, your Eclipse is equipped with stock 6-1/2" speakers that can be replaced with 5-1/4", 6-1/2" or even 6"x9" speakers. An adapter bracket is required, and it's included free with your speaker purchase.

If you choose to install component speakers (a great idea for a car like the Eclipse), remember that you'll need to fabricate new mounting brackets if you're planning to install the new tweeters in the stock dash locations. Your woofers will include a set of mounting brackets for the doors.

Removing and replacing the door speakers in the Eclipse isn't difficult, but it does involve several steps, so it's good to work slowly and it's even better to keep track of the various Phillips screws you'll be removing as you remove the door panels and speakers. It's a lot easier to put something back together when you know how it came apart.

Tools needed: Panel tool, Phillips screwdriver, small flat blade screwdriver, socket wrench and 10mm socket

Rear side speakers

This is where the Coupe and Spyder begin to diverge a bit, though the aftermarket speaker selection remains the same no matter which stock stereo or body style you're working with. When it comes to replacing the rear dual-voice coil speakers, you'll want to look for same-size models or choose from a variety of 5-1/4" or 6-1/2" speakers. The difference is in how you get to the factory speakers. Spoiler alert: the Coupe is easier.

It takes a bit of work to reach the Coupe's rear side speakers. (Crutchfield Research Photo)


To begin, you'll use a panel tool to pry up and remove the door scuff plate. That will expose a Phillips screw, which you'll remove. Next, you'll lift the front edge of the rear seat bottom cushion to release two clips that hold it in place. Remove the cushion, then fold down the seat backs and remove the two Phillips screws located at the rear edge of each rear side panel. Pry out the side panel to release the retaining clips, then set the panel to the side in a safe place.

Now, you're in the homestretch. Remove the four Phillips screws securing the speaker, pull it out, and disconnect it. Connect the speaker wiring adapter of your new speaker to the vehicle speaker harness, then secure the speaker with the screws previously removed.

Test the speakers to make sure they're working and, if they are, button everything up by reversing the steps above. Illustrated, step-by-step instructions can be found in your Crutchfield MasterSheet.

Tools needed: Panel tool, Phillips screwdriver

Installing new rear speakers in the open-air Eclipse is a more complicated task. It takes some rather sophisticated machinery to make a power-operated top do its thing, so there's less space available for speakers and subs.

The rear panel speakers are easy to find (they're right at the base of the panel, near the seat bottom), but getting to them takes a fair amount of work. And, once you're in, some modifications may be necessary in order to install a set of aftermarket speakers in this location.

Your Crutchfield MasterSheet contains Illustrated, step-by-step instructions, but if you're not feeling confident about your car audio installation skills, you may want to leave your Eclipse Spyder in the hands of professional installers.

Tools needed: Panel tool, Phillips screwdriver, socket wrench, 12mm socket

Bass in your Mitsubishi Eclipse

The Rockford Fosgate system, which was optional on the Eclipse Coupe and standard on the Spyder, includes a factory dual voice coil subwoofer. The Coupe sub is roughly equivalent in size to a 10" sub, while the Spyder's is more of an 8" model. In either case, you'll probably need to re-drill the mounting screw holes when you install an aftermarket sub.

They're both rated at 2 ohms and powered by an amp located up front, behind the right-hand kick panel. The coupe's sub is located in the trunk and the ragtop's is located in the center of the rear seat (see photo above) — mostly because there's precious little room in the trunk once the top is stowed.

Honestly, there's precious little room in either trunk, but you knew this wasn't a Montero when you bought it. If your coupe is not equipped with a factory sub, you're looking at a 25" W x 13" H x 22" D space for a sub box – which means you're probably really looking at our selection of powered subwoofers. For the record, the ragtop is even tighter, at a duffle bag-friendly 45" W x 10" H x 13" D

Other options for your Mitsubishi Eclipse

There are plenty of other ways to improve your Eclipse. Here are some of the ways Crutchfield can help.

Speaker baffles

For small, sporty cars like the Eclipse, a set of waterproof foam baffles can help reduce noise and maximize door speaker performance. The soft baffles compress easily within the doors, forming a seal that reduces panel vibration and improves sound.


If you're really serious about sound, installing Dynamat in your Eclipse will help keep noise and rattles to a minimum and allow you to enjoy your new stereo to the fullest.


Installing a security system in your Eclipse isn't easy (security systems rarely are), but it's less complicated than it could be. 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.

    I have installed an atoto s8 pro plus head unit in my 08 eclipse gs with a Rockford fosgate system. I am using the axxess mito-01 as an interface. It appears that the amp is not turning on to drive its requisite speakers. The head unit has an amp turn on wire and an acc wire, and the android software has a setting to ensure that the amp turn on wire gets power from the head unit. It also has 5 rcas, 2 sets of two for the door speakers and one for the sub woofer. I feel like there's something I am missing with the wiring from the head unit to the harness and on to the car's factory harness. Any thoughts?

    I have a 2008 Eclipse SE with the Rockford Fosgate system. If I buy a head unit with 2 RCS preamp outputs, do I still need to buy the $100 wiring harness to hook into the factory RG system? Or do the 2 Pre-Amp outputs take care of this connection?

    I just bought an 07 spyder and realized the guy who had it before me removed the sub! I got a replacement, but there's a female harness with 4 connectors (stock from the car that seems to be what the stock sub hooked up to). I can't find any harness or wiring that'll clip the new sub into the stock harness. Can someone help me with this or do I just cut the harness and splice the wires together?

    Chivon, Hopefully, someone will offer some advice here, but you should also check out some owners' forums. If you decide you want an aftermarket sub, our advisors are available via phone or chat.

    I have an '08 Spyder GT that I'm no longer getting sound from any of the speakers. I've checked the fuses but all are good. The next thought I have is that the amp may have died, but based on the description above (that half the speakers are wired into the receiver and half into the amp) now I'm not so sure. When it stopped working, I was idling and the stereo was on but turned down to conversation level. I heard a semi-loud pop and then silence. No static, no crackling, nothing. The display on the radio was still on and functional. 1. Any ideas what else this could be? 2. If it is the amp, do you know where I could find the specs for the amp and how to replace it. I know where it's located, but I'm a stereo neophyte.

    Heather, Not a bad guess, so it's worth looking into. The factory amp is located behind the right-side kick panel. If the amp is the culprit, you can look for a factory-style replacement, but you should also consider an aftermarket amp (and maybe some speakers). Give us a call and talk to one of our advisors. We can help you find what you need to bring your system back to life.

    John Thanks for the info concerning the Ohms on the rear speakers. Here is my other question: can I put a set of 3ohm components in the place of the 4ohm speakers without an issue?

    Tim, No prob, and thanks for the question! With this one, we're getting into some system design stuff, though, so the best thing to do is to have an actual conversation with a real live human.

    Every single tutorial I run across for my 2007 Eclipse GT with premium fosgate system fails to mention the Ohms for the rear side panel 6.5 speakers. Can you please tell me so I can match the same ohm as the factory? The front door speakers are 2 ohm, but what are the rear?

    Tim, The Rockford Fosgate system's rear side panel speakers are 4-ohm models. Hope that helps!
